Abstract
The invention discloses an optimization method for firmware updating based on a high-pass baseband chip, in order to solve the problems of low efficiency and poor stability of the high-pass original firmware updating method. The method comprises the following steps of: stage 1, receiving a firmware file from a PC (Personal Computer) end through a high-speed USB (Universal Serial Bus) and storing in an RAM (Random Access Memory); and stage 2, downloading the firmware file in the RAM into a flash so as to fulfill the aim of high-speed firmware updating. By newly establishing a new download process and canceling the concept of packet in a download program, the speed of updating firmware can be greatly increased. Meanwhile, by changing a data transmission mode and an error mechanism, the stability of firmware updating and correctness for transmitted data are improved.
Description
Technical field
The present invention relates to the optimization of the firmware update of baseband chip, can improve firmware burning speed more than 5 times.Related in particular in process of production, improved based on the efficient of the Software Production burning of the 3G mobile of high pass baseband chip and 3G wireless Internet card.
Background technology
The high pass baseband chip is mainly used in the 3G wireless Internet card, in the telecom terminal products such as 3G mobile, especially high-end intelligent machine.The required firmware of normal operation of baseband chip comprises the program that makes the baseband chip normal operation, to the reception configuration of network signal, basic note, phone, data, services, and the interface that offers application program of mobile phone.
Based on the 3G mobile of high pass baseband chip, the end product of 3G wireless Internet card need be with the firmware burning of baseband chip in flash when plant produced.The process of downloading burning need be by the control that downloads, and the efficient that therefore downloads directly influences the efficient of plant produced and the quality of product.Also need downloading when unique user carries out firmware update simultaneously by baseband chip.Qualcomm provides by the QPST software of PC end control and required the downloading of specific baseband chip operation, as the instrument of firmware update.
The original firmware update flow process of high pass is divided two parts: at first being QPST moves baseband chip among the RAM that required downloading burn into baseband chip (general 1～2 second); To be QPST split into the packet of maximum 1K with firmware file for next, sends downloading of baseband chip to through USB; Downloading of baseband chip advanced flash with the packet that splits burning successively, if make a mistake then stop immediately, if transmission is normal, after the bag result of QPST as received basis microarray strip, will continue the fractionation firmware until end of transmission.(data of 10M need 100 seconds)
The maximum time resource consumption of the method is to be that round-robin has carried out the transmission of 1K packet; And on the market based on the firmware of the 3G mobile of high pass baseband chip at least more than 50M even more; Therefore adopt the method speed of this firmware update slow; Be merely about 100k/s, in case and make mistakes then cause system in case of system halt, stability of data transmission is not high.
Summary of the invention
Deficiency to prior art; The object of the present invention is to provide optimization method based on the firmware update of high pass baseband chip; Can improve speed of download more than 5 times, be very easy to research and development and DIY user's use, reduce production time and the cost of factory in the firmware update link.
Based on the optimization method of the firmware update of high pass baseband chip, described content of the present invention has comprised the Control Software of PC end, is used for replacing the QPST instrument, and the required two parts that download of baseband chip operation.
The optimization method of firmware update comprises three parts:
1, the Control Software of described PC end is moved required newly downloaded program with baseband chip and is burnt in the storer of baseband chip general 1～2 second of time.
2, the Control Software of described PC end sends firmware file to the newly downloaded program of baseband chip through USB; Newly downloaded program only leaves packet among the internal memory RAM in.The data of 10M need about 1 second.
3, the Control Software of described PC end is sent " transmission OK " and is ordered to baseband chip, baseband chip download with the firmware data of depositing among the internal memory RAM through CRC check after, be burned onto flash by downloading of baseband chip.The 10M data need 12 seconds.
The invention has the beneficial effects as follows: improve the speed of firmware update, the cost that saves time is greatly increased work efficiency; Replacing error handling processing mechanism with the validity of CRC raising data transmission, improves the stability of chip.
Description of drawings
Fig. 1 is original method software flow synoptic diagram;
Fig. 2 is the software flow synoptic diagram of optimization method of the present invention.
Embodiment
How further specify the present invention below in conjunction with accompanying drawing realizes:
Like accompanying drawing 1, shown in 2: the Control Software of PC end at first reads firmware file, whole file is calculated the CRC check sign indicating number of 2 bytes.
The baseband chip operation downloads and switches to new firmware update pattern, applies for a big internal memory; The decoding of the bag of cancellation PC end forward data.Represent that just next bag no longer is a HDLC protocol data bag.The file size of the firmware of noting that transmits and crc check code, and the start address of depositing in flash, and return an ACK; After the Control Software of PC end obtains ACK then, directly whole firmware image is sent to baseband chip, baseband chip receives firmware data, deposits in the internal memory.
After baseband chip received 0x21 order, 2 byte crc check codes according to the storage of first order carried out the crc verification to the firmware among the RAM, and verification OK then advances flash with the whole firmware burning among the RAM.If verification not through return the Control Software of fail to PC end, PC end Control Software is responsible for transmitting firmware again to RAM.
