Description

Online upgrade configuration method and device for DSP

Technical Field

The invention relates to the technical field of online upgrade of Digital Signal Processors (DSPs), in particular to an online upgrade configuration method and device of DSPs.

Background

DSP (digital signal processor) has been widely used in various fields such as communications, computers, control, consumer electronics, etc. With the wide application, the maintainability of the product and the continuous change of the product requirement are considered, and the DSP program needs to be updated frequently. The DSP generally adopts Norflash as a storage medium of a program, and the traditional DSP program updating method adopts a special DSP simulator, wherein one end of the simulator is connected with a JTAG interface (JointTestActionGroup) of a DSP chip, the other end of the simulator is connected with a computer USB port which is provided with CCS software and a DSP simulator driver, the computer USB port is connected with the DSP chip to be upgraded by operating the CCS software in the computer, an executable program to be upgraded is loaded into a memory area in the DSP, the Norflash writing program is operated, and the executable program is written into a Norflash appointed space address.

It follows that the conventional DSP upgrade method has the following disadvantages:

1) The upgrade process needs to power off the equipment and restart the power-on operation, namely the DSP simulator can be connected under the power-off condition, the power-on operation is performed after the connection of the DSP simulator is successful, and the burning program is completed through the operation of CCS software.

2) The operation process is long-the time for installing, debugging and dismantling the software and hardware environment of the upgrade program is far longer than the actual program writing time;

3) The software and hardware upgrading environment is complex, the operation flow is complex, namely, a computer provided with CCS software and a DSP simulator driver and a DSP special simulator are used as an aid for upgrading, so that the CCS software environment is huge and complex, and a non-professional DSP developer is not easy to operate;

4) Depending on the JTAG interface state, the upgrade must transmit command and data through the JTAG interface, the plug operation can lead to abrasion of JTAG related interfaces, so that instability of the JTAG interface can occur, thereby not only affecting the success rate of the upgrade program, but also affecting the service life and running stability of the product.

In addition to the above-mentioned conventional program upgrading method, there is another upgrading method in the prior art: judging whether the DSP is in an upgrade mode or not when the DSP program is started by the improved Boot Loader program, and loading the upgrade program if the DSP is in the upgrade mode; if in the normal start mode, the DSP program is started normally. The method for judging the upgrade mode is divided into two types, one is state judgment obtained through software, and the other is state judgment through a hardware switch.

However, both methods have the defect that the Boot Loader program needs to be powered up again in the upgrading process, and the upgrading process can be started only by the fact that the Boot Loader program is powered up again and started and operated, so that the online upgrading function is not really realized, and the software is not upgraded while the DSP program is normally operated. In the first method, the acquisition of the software state needs to wait for a certain time, and when the DSP program is started normally, the starting time is increased, so that unnecessary starting waiting time is generated. The implementation of the second method depends on a hardware switch, and hardware condition support is needed, so that not all boards have the hardware condition, and the popularization is difficult.

Fig. 2 is a schematic diagram of an application scenario in which the online upgrade configuration method of the DSP according to the embodiment of the present invention is applied to a processor connected to the DSP through a network port, as shown in fig. 2, the network port of the DSP is not led out and cannot be directly connected to a computer, but hardware having a high-speed interface (PCIe, rapidio, etc.) and a network port, for example, a processor, may be connected through the high-speed interface to serve as a relay. The data to be upgraded is passed through the high-speed interface to the processor and then through the network port to the DSP and vice versa. Judging whether the file to be upgraded is selected successfully or not in the processor, if so, sending a file transmission handshake message to be upgraded to the DSP, executing a handshake process, and if not, finishing upgrading to generate alarm information; sequentially sending a plurality of data message packets of a file to be upgraded to the DSP according to a preset transmission mechanism, and acquiring a whole packet data verification result fed back by the DSP; when the verification result is incorrect, finishing upgrading and generating alarm information; and when the verification result is correct, ending the transmission of the file to be upgraded, and finishing the online upgrade configuration of the DSP.

The online upgrade configuration method of the DSP according to the embodiment of the present invention is described below with reference to fig. 3 to 7.

As shown in fig. 3, an online upgrade configuration method of a DSP is provided, and the method is applied to the processor connected to the DSP through a network port in fig. 2, as shown in fig. 3, and includes, but is not limited to, the following STEPs (STEP, S for short):

s101: judging whether the file to be upgraded is selected successfully, if so, sending a file transmission handshake message to be upgraded to the DSP, executing a handshake process, and if not, ending the upgrading to generate alarm information.

S102: sequentially sending a plurality of data message packets of a file to be upgraded to the DSP according to a preset transmission mechanism, and acquiring a whole packet data verification result fed back by the DSP;

when the verification result is incorrect, finishing upgrading and generating alarm information; and when the verification result is correct, judging whether a DSP feedback data writing success result is received within a preset time number, if so, generating a transmission completion message and sending the transmission completion message to the DSP, otherwise, finishing upgrading and generating alarm information.

Specifically, in the upgrading process, whether the file to be upgraded is successfully selected or not is judged by judging the selection of the file to be upgraded. The judgment can be made by checking whether the file exists, whether the file authority meets the requirement or not, and the like. If the file selection is successful, entering the next step; if the file selection fails, the upgrading is finished, and alarm information is generated.

If the file selection is successful, sending a file transmission handshake message to be upgraded to the DSP, and executing a handshake process. The handshake messages are used to establish the transmission channel and ensure the readiness of both parties. In the handshake process, the two parties can exchange and verify information, and the correctness and the integrity of transmission are ensured.

After the handshake is successful, the file to be upgraded is segmented into a plurality of data message packets according to a preset transmission mechanism, and the data message packets are sequentially sent to the DSP. After the DSP receives the data messages, the whole packet data verification is carried out to verify the integrity of all the received data messages.

After the processor receives the verification result, executing judgment whether the DSP feedback data is received within the preset time number, and if the processor receives the DSP feedback data within the preset time number, generating a successful writing result. And the processor judges after receiving the whole packet data verification result fed back by the DSP. If the check result is incorrect, it indicates that there may be error or lost data in the transmission process. In this case, the upgrade is ended and an alarm message is generated for timely processing.

Further, after the whole packet data verification is completed, the data writing result judgment is executed, and if the verification result of the whole packet data verification is correct, the file to be upgraded is successfully transmitted to the DSP. And ending the file transmission to be upgraded and completing the online upgrade configuration of the DSP. It will be appreciated that the DSP will perform a write operation of the file to be upgraded after the integrity check of the entire packet of data is completed.

step 201: sending a file transmission handshake message to the DSP based on a network port protocol corresponding to the network port, and starting timing;

step 202: judging whether the DSP response message is received within a preset counting time, if so, sequentially sending data message packets to the DSP according to a preset transmission mechanism, and if not, ending upgrading.

Specifically, after the files to be upgraded required by the current upgrade are determined, a file transmission handshake message is sent to the DSP, a waiting timer is started, handshake failure is displayed when the waiting time is exceeded, and the current online upgrade is ended.

Based on the foregoing embodiments, as an optional embodiment, in the method for configuring online upgrade of a DSP according to the present invention, the step of sequentially sending data packets to the DSP according to a preset transmission mechanism includes:

step 301: transmitting a data message packet to the DSP based on a network port protocol corresponding to the network port and starting timing;

step 302: judging whether the timing reaches the preset counting time, if not, repeating the step, and if so, executing step 304;

step 303: based on the network port protocol corresponding to the network port type, sending a plurality of data message packets in the file packet to be upgraded to the DSP packet by packet according to a preset time interval, judging whether a response message fed back by the DSP is received within the preset time, if yes, executing step 304, otherwise, executing step 306;

step 304: judging whether a first response message corresponding to the first data message packet fed back by the DSP is correct, if so, executing a step 305, otherwise, executing a step 306;

step 305: transmitting a second data packet;

step 306: and retransmitting the first data packet.

Specifically, after the handshake is successful, the processor continuously sends the data message to be upgraded to the DSP, and once the processor sends one packet of data message, the waiting timer is started, and after receiving the receiving message ACK returned by the DSP, the processor sends the next packet.

After receiving the complete file to be upgraded, carrying out data verification of the whole package of the file, and sending a verification result to the processor. The verification aims to mainly prevent errors of the DSP upgrade data in the transmission process. If the verification result is correct, the processor interface prompts that the data transmission is successful, and the next upgrading stage is entered. If the verification result is incorrect, the processor prompts that the data transmission fails, and the online upgrading is finished, and corresponding alarm information is generated. At this time, the software and hardware environment needs to be checked again, so that online upgrade is carried out again after reliable and correct transmission is ensured.

The format of the data packet is 6 field data, and 6 fields respectively represent a total packet number field, a packet sequence number field, a total packet length field, a first CRC check code, a message field to be upgraded and a second CRC check code.

Specifically, the first CRC check code is a check result obtained by performing CRC check on the total packet number field, the packet sequence number field, and the total packet length field. And the second CRC check code is a check result obtained by performing CRC check on the message field to be upgraded.

The invention also provides a device for configuring online upgrade of the DSP, which comprises: the communication establishing module is used for judging whether the file to be upgraded is selected successfully, if so, sending a file transmission handshake message to be upgraded to the DSP, executing a handshake process, and if not, finishing upgrading to generate alarm information;

the data transmission module is used for sequentially sending a plurality of data message packets of the file to be upgraded to the DSP according to a preset transmission mechanism and acquiring a whole packet data verification result fed back by the DSP;

the online upgrade configuration module is used for judging the operation to be executed according to the verification result, and ending the upgrade when the verification result is incorrect, so as to generate alarm information; and when the verification result is correct, ending the transmission of the file to be upgraded, and finishing the online upgrade configuration of the DSP.

Based on the foregoing embodiments, as an optional embodiment, the DSP online upgrade configuration apparatus includes a DSP online upgrade configuration system, where the DSP online upgrade configuration system includes a communication establishment module, a data transmission module, and an online upgrade configuration module

Before data transmission starts, the DSP online upgrade configuration system sends a handshake message to the DSP, starts a waiting timer, displays handshake failure if the waiting time is exceeded and does not receive a response message, and finishes the online upgrade. Fig. 4 is a schematic diagram of a handshake message format according to an embodiment of the present invention, where, as shown in fig. 4, message types are divided into: upgrade data handshake and transmission message, upgrade data handshake and transmission response message, online upgrade instruction message and online upgrade instruction response message. As shown in fig. 4, CRC check is performed on the message type field and the message body field and the message tail is filled.

After the handshake is successful, the DSP online upgrade configuration system continuously transmits a data message to be upgraded to the DSP. Figure 5 is a diagram of a data transmission message format according to an embodiment of the present invention,

as shown in FIG. 5, before the message cutting is performed on the file to be upgraded, CRC of the whole file to be upgraded is attached to the end of the file to be used as verification. Fig. 7 is a schematic diagram of a data format to be upgraded according to an embodiment of the present invention, as shown in fig. 7. The file to be upgraded is equally divided into a plurality of data messages (except the last packet of data messages, the length of which is variable) according to the block size of Norflash, and the data messages are sent one by one. And performing CRC (cyclic redundancy check) on the total packet number field, the packet sequence number field and the total packet length field, filling the first CRC of the message, performing CRC on the message field to be upgraded, and filling the second CRC of the message.

And starting a waiting timer when the DSP online upgrading configuration system transmits one packet of data message, and transmitting the next packet after receiving a receiving message ACK returned by the DSP. And if the received message NAK message returned by the DSP is received or the response message of the DSP is not received, the packet data is retransmitted for 3 times at most, if the received message ACK from the DSP is not received for 3 times, the data transmission is failed, the online upgrade is ended, at the moment, the software and hardware environment is required to be checked again, and the online upgrade can be restarted after the reliable and correct transmission is ensured. Fig. 6 is a schematic diagram of a transmission process of a plurality of data packets of a data packet to be upgraded according to an embodiment of the present invention, as shown in fig. 6. The specific implementation function is mainly implemented by adopting the following four functional functions:

a)CtrlDataSend

the function sends a handshake flow related message.

b)FileDataSend

The function sends a data message to be upgraded.

c)DataRecv

The function receives the message from the DSP, and after the receiving is finished, the function is transferred to analysis processing according to the type of the message.

d)StatusDataParse

The function parses the status message from the DSP and operates according to the flow.

In an example, the present invention further provides a method for configuring online upgrade of a DSP, which is described below by taking application of the method to the DSP in fig. 2 as an example, where the method includes:

step 1: receiving a file transmission handshake message to be upgraded, and feeding back a response message;

step 2: acquiring a plurality of data message packets of a file to be upgraded, and feeding back a response message corresponding to each data message packet by packet;

step 3: performing whole packet data verification on a plurality of data packets to obtain a verification result, and judging an operation to be executed based on the verification result; when the verification result is correct, executing data writing operation based on the data packet; and when the verification result is incorrect, feeding back an upgrade failure result.

The DSP receives a message to be upgraded sent from a processor carrying a file to be upgraded, as shown in fig. 5, according to the interface format of the network port, performs CRC verification first, extracts the message segment to be upgraded if the CRC is correct, and puts the message segment to be upgraded into a buffer area, where the storage start address is the end of the storage address of the data to be upgraded, as shown in fig. 7.

When the DSP receives the last packet of data message, it then starts to perform CRC check on the entire file, as shown in fig. 7. And if the CRC of the whole file is correct, transferring to a file read-write step to be upgraded.

Specifically, DPS reads and writes NorFlash through the EMIF bus, writes the file to be upgraded in the designated address, and performs read-back verification. If the read-back verification is successful, the upgrade is sent to the processor, otherwise, the online upgrade is sent to fail.

Based on the above embodiments, as an alternative embodiment, since the space in the DSP chip is small, the cache file of the file to be upgraded is stored at the DDR outside the DSP chip and at a continuous address, as shown in fig. 7. The receiving and piecing together of the complete file to be upgraded is shown in fig. 7. The data message field to be updated of the second packet is stored immediately following the last address of the message field to be updated of the first packet, as shown in fig. 5, by combining the number field of the packet and the total number field of the packet in the packet and the number of the packets received currently, whether the packet is the last packet is comprehensively judged, and the last packet is received, namely the whole file to be updated is completely received. The specific implementation function is mainly implemented by adopting the following three functional functions:

a)FileDataRecv

the function receives the message from the processor, and after the receiving is finished, the function shifts to analysis processing.

b)FileDataParse

The function parses the message from the processor and operates according to the flow

c)FileDataSave

The function sequentially stores and hashes the extracted data message fields to be upgraded according to the addresses.

The verification of the file to be upgraded is performed by calculating CRC 32. The checking module is mainly used for preventing error checking of the file data to be upgraded in the transmission and storage processes. The data verification of the file to be upgraded is carried out by adopting a mode of calculating CRC32, and the method comprises the following two steps:

in the case of explicitly updating the file CRC32 check polynomial and CRC deposit location, calculation interval, after the DSP receives data from the processor, the DSP checks the CRC according to the message format, as shown in fig. 4 and 5.

After the DSP finishes receiving all the data packets in the buffer, CRC check is performed on the entire file to be upgraded, as shown in fig. 7.

Only when all the above CRC checks are correct, the next step of reading and writing NorFlash can be entered.

The NorFlash read-write flow is divided into the following three steps:

a) Removing the Norflash write protection to finish the operation of erasing the Norflash designated area;

b) Entering an updating flow, and finishing writing each block one by one;

c) And checking the data in each block, and performing CRC (cyclic redundancy check). And (3) if all CRC checks correctly, the online upgrade is successful, otherwise, the step a) is returned until the read data CRC checks correctly.

The implementation function mainly comprises the following three functions:

a)Erase Flash(unsigned Flash Base, unsigned sector Addr);

the function erases a certain sector of Nor Flash, every 1024 x 1024 bytes of sector size, and 128 sectors are all available. Wherein Flash Base is a Flash Base address, and sector Addr is a sector number.

b)Write Flash(unsigned Flash Base, unsigned offset, unsigned short *data);

This function writes to the specified Nor Flash address (base address+offset). Wherein Flash Base is a Flash Base address, offset is an offset, and data is a data address to be written into Flash.

c)Read Flash(unsigned Flash Base, unsigned offset, unsigned short *data)；

This function performs a read operation on the specified Nor Flash address (base address+offset). Wherein Flash Base is a Flash Base address, offset is an offset, and data is a read data address.

When the file is written, the size of the Flash space is recorded, namely, the interval needing to participate in calculation is determined, the position of the CRC32 is determined, and according to the address record, the data is read back and CRC check is carried out. This calculated CRC is compared with the CRC value contained in the file.

In summary, the online upgrade configuration method of the DSP provided by the present invention is applied to a processor connected to the DSP through a network port, and the file package to be upgraded is imported in real time through an external processor, so that no special hardware design is required in the whole online upgrade process, no modification of the Boot Loader of the DSP is required, only the network port of the DSP chip is required, and meanwhile, the occurrence of data anomalies in the whole upgrade process can be detected through CRC check, if the data anomalies immediately terminate the upgrade process, and the process can return to the initial state, without affecting the subsequent normal operation of the DSP application.
