Technical Field

The embodiment of the application relates to the technical field of electronics, in particular to a system starting method and device.

Background

With the development of mobile communication, a system (e.g., an embedded system) composed of at least one device is generally powered by a battery. In order to extend the operating time of the system with limited battery capacity, it is desirable to save power consumption of the system.

It is common to divide the system into a constant electrical area and a very electrical area. When the system is in a non-working state, the power supply control end of the system can control devices in a very electric area to be powered down. When the system is required to enter a working state, the power control end controls devices in the very electric area to be electrified so as to finish the starting of the system.

In the starting process of the system, devices in a very electric area need to be initialized after being electrified until the starting is completed and the devices can normally work. But this initialization process takes a long time, affecting the start-up rate of the system.

As shown in fig. 5, the method may include the following process:

201. the initialization parameters required for the first device to start are stored in the memory space.

The initialization parameters are parameters determined after the system is powered on and started for the first time. If the first device is the control end of the second device, the initialization parameter may be a parameter determined by the first device and the second device through multiple interaction negotiations after the system is powered on and started for the first time.

202. The first device is controlled to enter a non-working state, wherein the non-working state comprises a power-down state or a standby state.

Therefore, the embodiment of the application omits the process of calculating the first device or negotiating with other devices to obtain the initialization parameters in the system starting process, reduces the time consumption of system starting, prolongs the working time of the system and simultaneously realizes the quick starting of the system. For example, for a camera, shooting can be started as soon as possible, and omission of an emergency is avoided.

Referring to fig. 6, fig. 6 is a flowchart of another system start-up method according to an embodiment of the present application, and fig. 6 illustrates a start-up process of a first device and a second device capable of performing data interaction. The method may be applied to a system, such as the system 10 described in any of the foregoing figures 1-4. As shown in fig. 6, the method may include the following process:

301. the initialization parameters required for the first device to start are acquired from the second device controlled by the first device.

The first device and the second device can perform data interaction, and the first device can receive initialization parameters sent by the second device through the data line so as to acquire the initialization parameters.

The initialization parameter is a parameter determined by the first device and the second device through multiple interaction negotiations when the system is started for the first time, and may include at least one of the following information: the phase information of the second device, the clock information of the second device, the operating mode of the second device, the hash value of the security image, the operating voltage of the second device.

The initialization parameters are also different for different first and second devices. For example, when the first device is an EMMC host and the second device is an EMMC particle, the initialization parameter may include at least one of the following information of the EMMC particle: phase information, clock information, operating mode, operating voltage, etc. When the first device is SDIO host and the second device 102 is SDIO Client, the initialization parameter may include at least one of the following information of SDIO Client: phase information, clock information, operating mode, operating voltage, etc. When the first device is a DDR host and the second device 102 is a DDR granule, the initialization parameters may include DDR Training (Training) results, which may include, for example: phase information of DDR particles. When the first device is an SVB and the second device 102 is a chip set by the SVB, the initialization parameter may include an operating voltage of the chip set by the SVB.

302. The acquired initialization parameters are saved in the memory space.

The memory space may include SRAM, registers, etc., as long as it has a memory function, and the embodiment of the present application does not limit the form of the memory space.

The memory space can be located in a constant power area in the system, and the memory space is still in an operating state when the system is in a non-operating state so as to avoid the loss of initialization parameters. For example, as shown in the foregoing fig. 1 to 4, the storage space may be located in the power controller 105 of fig. 1 or the PMC of fig. 2 to 4.

The first device and the storage space can perform data interaction through the data line, and the first device can send the acquired initialization parameters to the storage space to save the initialization parameters. As shown in fig. 1, the first device 101 is connected to the power controller 105 through a data line, the first device 101 transmits initialization parameters to the power controller 105 through the data line, and the power controller 105 stores the initialization parameters in a memory space.

303. The first device is controlled to enter a non-working state, wherein the non-working state comprises a power-down state or a standby state.

This process may be performed by the power controller 105 of fig. 1 or the PMC of fig. 2 or the MCUs of fig. 3 and 4, and may send a hardware signal to the DC-DC corresponding to the first device to control the DC-DC corresponding to the first device to be turned off, thereby controlling the first device to enter the inactive state. Taking the PMC to control the first device to enter the power-down state as an example, the PMC sends a shutdown signal to the DC-DC (e.g., DC-DC2 of fig. 1 to 4) corresponding to the first device when receiving an instruction for instructing the system to enter the non-operating state. For example, the PMC may send a low signal (i.e., a 0 signal) to the DC-DC corresponding to the first device to control the DC-DC corresponding to the first device to turn off.

304. The second device is controlled to enter a standby state from a pre-standby state.

After the second device enters the standby state, the second device is in a low power consumption working mode, and the process of controlling the second device to enter the standby state is described below by taking EMMC particles and SDIO clients as examples.

In one example, the second device is an EMMC particle having two modes: a load (Boot) mode and a transfer (transfer) mode, different modes corresponding to different states. When the EMMC particles are electrified and started for the first time, the EMMC is required to be initialized to a Boot mode, and the EMMC particles enter a state corresponding to the Boot mode and perform a corresponding initialization flow. And initializing the EMMC particles into a transfer mode, and entering a state corresponding to the transfer mode by the EMMC particles and performing a corresponding initialization flow until the starting is completed, so that the EMMC particles are in the transfer mode before standby. transfer mode corresponds to three states: sleep state (sleep state), waiting state (standby) and transfer state (transfer state), the transfer state in transfer mode before the EMMC particle stands by, and the control of EMMC particle entering standby state is to control the EMMC particle to be converted from transfer state in transfer mode to sleep state in transfer mode.

This process may be performed by EMMC host and power controller 105 in fig. 1 (or PMC of fig. 2 or MCU of fig. 3 and 4). Taking EMMC host and PMC control as an example, first, the PMC may control the DC-DC to be turned off to a DC-DC transmission hardware signal for providing VCC among DC-DCs corresponding to EMMC particles, and the DC-DC for providing VCCQ is still in an on state. This process may refer to the foregoing description of the process 303, and the embodiments of the present application are not described herein. Thereafter the EMMC host sends cmd7 to the EMMC particles to switch the EMMC particles from the transfer state in transfer mode to the standby state in transfer mode. The EMMC host then sends cmd5 to the EMMC particles to cause the EMMC particles to be converted from the standby state in transfer mode to the sleep state in transfer mode, thereby controlling the EMMC particles to enter standby state.

In another example, the second device is an SDIO Client, and the process of controlling the SDIO Client to enter the standby state may be performed by a chip set by the SDIO Client, which may control the SDIO Client to enter the standby state through a low power consumption control protocol.

It should be noted that, the other devices in the very electric area in the control system are also required to enter the non-working state, and the other devices in the very electric area are controlled to enter the standby state.

305. And when the wake-up source is received, acquiring initialization parameters stored in the storage space.

As shown in fig. 1-4, the wake-up module 104 may send a wake-up signal to the power controller 105 (or PMC or MCU) upon receipt of the wake-up source. The power controller 105 (or PMC or MCU) controls the first device to enter an operating state, i.e., controls the first device to enter a powered-up state, based on the received wake-up signal. The first device then retrieves the initialization parameters from the memory space.

The power controller 105 (or PMC or MCU) may send a hardware signal to the DC-DC corresponding to the first device to control the DC-DC corresponding to the first device to be turned on, thereby controlling the first device to enter the working state. Taking the PMC to control the first device to enter the power-on state as an example, the PMC sends an on signal to the DC-DC (e.g., DC-DC2 of fig. 1 to 4) corresponding to the first device based on the received wake-up signal. For example, the PMC may send a high signal (i.e., a 1 signal) to the DC-DC corresponding to the first device to control the DC-DC corresponding to the first device to turn on.

It should be noted that, the power controller 105 (or PMC or MCU) also needs to control other devices in the system located in the very electric area to enter the working state based on the received wake-up signal, and the control process may refer to the foregoing description, and the embodiments of the present application are not described herein.

306. And controlling the first device to execute an initialization flow according to the initialization parameters.

The first device is restored to a pre-standby state according to the initialization parameters, and interaction with the second device is not needed in the process.

307. And controlling the second device to restore the state before standby.

The second device is not powered down, so that the second device is still in a standby state after being awakened. The recovery process of the second device of different types is different, and the second device will be described below as an EMMC particle.

As can be seen from the foregoing process 304, the EMMC granule standby state is sleep state in transfer mode, and the pre-standby state is transfer state in transfer mode. And controlling the EMMC particles to restore to a standby state, namely controlling the sleep state of the EMMC particles in the transfer mode to be converted into the transfer state in the transfer mode.

In accordance with the foregoing procedure 304, taking EMMC host and PMC control as an example, first, the PMC may first send a hardware signal to the DC-DC for providing VCC among the DC-DCs corresponding to the EMMC particles to control the DC-DC to be turned on, and the DC-DC for providing VCCQ is still in an on state. Thereafter the EMMC host sends cmd5 to the EMMC particles to switch the EMMC particles from sleep state in transfer mode to standby state in transfer mode. The EMMC host then sends cmd7 to the EMMC particles to cause the EMMC particles to be converted from the standby state in transfer mode to the transfer state in transfer mode, thereby controlling the EMMC particles to resume the pre-standby state.

After both the first device and the second device are restored to the pre-standby state, other initialization processes of the system may be performed. For example, the first device may read the mirror image from the second device, run the mirror image, and so on.

When the system is powered on and started for the first time, the initialization parameters do not exist in the storage space, the first device needs to perform interactive negotiation with the second device to obtain the initialization parameters, and then the initialization process is executed.

The complete start-up procedure of the system will be described below taking EMMC host and EMMC particles as examples. Referring to fig. 7, fig. 7 is a system start-up flowchart provided in an embodiment of the present application, and fig. 7 shows three stages of the start-up flowchart. In the first stage, after the system is powered on or wakes up, it needs to determine whether the EMMC particles are in sleep state in transfer mode (i.e. determine whether the EMMC particles are in standby state). When the EMMC particles are not in sleep state in transfer mode, it means that the system is currently powered on for the first time, and a complete initialization procedure needs to be executed. The system initializes the EMMC particle to Boot mode, the EMMC host reads a generic bootloader (Universal Boot Loader, UBoot) image from the EMMC particle, and runs the UBoot image. When the EMMC particles are in sleep state in transfer mode, the EMMC host is restored by performing the processes 203 and 204 of fig. 5 or the processes 305 and 306 of fig. 6 described above. Thereafter, the foregoing process 307 of fig. 6 is performed to power up the VCC power supply of the EMMC particle, and then the EMMC host sequentially transmits cmd5 and cmd7 to the EMMC particle to restore the EMMC particle to the transfer state in the transfer mode, thereby controlling the EMMC particle to restore the standby state. As described in the foregoing process 307, the EMMC particles are at the transfer state in the transfer mode at this time, so that the EMMC particles do not need to be initialized to the Boot mode or the transfer mode. The EMMC host then reads the generic bootloader (Universal Boot Loader, UBoot) image from the EMMC particle and runs the UBoot image.

In the second stage, it is necessary to first determine whether the EMMC particles are in the transfer state in transfer mode. When the EMMC particles are not in the transfer state in the transfer mode, this indicates that the system is currently powered on for the first time, and a complete initialization procedure needs to be performed. The system initializes the EMMC particles to transfer mode, EMMC host reads a Kernel (Kernel) image from the EMMC particles, and runs the Kernel image. When the EMMC particle is in the transfer state in transfer mode, the EMMC host directly reads the Kernel image from the EMMC particle and runs the Kernel image.

In the third stage, it is necessary to first determine whether the EMMC particles are in the transfer state in transfer mode. When the EMMC particles are not in the transfer state in the transfer mode, this indicates that the system is currently powered on for the first time, and a complete initialization procedure needs to be performed. The system re-initializes the EMMC particles to transfer mode, EMMC host reads the file system from the EMMC particles, and runs an Application (APP). When the EMMC particle is in the transfer state in transfer mode, the EMMC host directly reads the file system from the EMMC particle and runs the APP.

In the process of running APP, if the system needs to enter a non-working state, the foregoing processes 201 and 202 shown in fig. 5 or processes 301 to 304 shown in fig. 6 may be executed, and the initialization parameters of the EMMC particles are saved. And powering down the VCC power supply of the EMMC particles, and then sequentially sending cmd7 and cmd5 to the EMMC particles by the EMMC host to control the transition of the EMMC particles from a transfer state in a transfer mode to a sleep state in the transfer mode, thereby controlling the EMMC particles to enter a standby state.

In the related art, when the system is in a non-working state, the power control end of the system controls the EMMC host and the EMMC particles to be powered down. When the system is required to enter a working state, the power control end controls the EMMC host and the EMMC particles to be electrified. The initialization parameters are obtained through interactive negotiation between the EMMC host and the EMMC particles, the system directly initializes the EMMC particles to a transfer mode in the first stage, and the EMMC particles do not need to be re-initialized in the second stage and the third stage. The process of the EMMC host and EMMC particle interaction negotiation and the process of initializing EMMC particles to transfer mode are time consuming. And the time consumption of one initialization of different EMMC types may be greatly different, resulting in unstable start-up duration of the system. Furthermore, initializing EMMC particles directly to transfer mode may not be compatible with the system, which is not supported by some systems.

In the embodiment of the application, when the system is in a non-working state, the initialization parameters required by starting the EMMC host are stored first, then the power-down or standby of the EMMC host is controlled, and the standby of the EMMC particles is controlled. Therefore, when the system is required to enter a working state, the stored initialization parameters can be directly acquired, so that the initialization parameters can be obtained by the EMMC host and the EMMC particles without interaction negotiation. And EMMC particles can be directly restored from standby state to pre-standby state without initialization. Therefore, the embodiment of the application omits the interactive negotiation flow of the EMMC host and the EMMC particles and the three initialization flow of the EMMC particles in the system starting process, and reduces the time consumption of system starting. And the system starting time is not influenced by EMMC particles, so that the stability of the system starting time is ensured. In addition, the compatibility problem with the system is not needed to be considered, and the applicability is wider.

In summary, in the method for starting the system provided by the embodiment of the present application, after the initialization parameters required for starting the first device are obtained from the second device controlled by the first device, the obtained initialization parameters are stored in the storage space, so as to control the first device to enter the non-working state, and control the second device to enter the standby state from the state before standby. When a wake-up source is received, the second device is controlled to restore the state before standby, the initialization parameters stored in the storage space are acquired, the first device is controlled to execute an initialization flow according to the initialization parameters, and when the system is started, the first device and the second device can acquire the initialization parameters without interaction negotiation because the stored initialization parameters can be directly acquired. And the second device can directly recover the pre-standby state from the standby state without initialization. Therefore, the embodiment of the application omits the interactive negotiation flow of the first device and the second device and the initialization flow of the second device in the system starting process, reduces the time consumption of system starting, prolongs the working time of the system and simultaneously realizes the quick starting of the system. For example, for a camera, shooting can be started as soon as possible, and omission of an emergency is avoided. And the system starting time is not influenced by the second device, and the system starting time difference is smaller for different second devices, so that the stability of the system starting time is ensured. In addition, the compatibility problem with the system is not needed to be considered, and the applicability is wider.
