Description

Method and device for starting electronic device

Technical field

The present invention relates to the field of electronic device technologies, and in particular, to a method and device for starting an electronic device.

Background technique

In order to improve performance, modern electronic equipment must also take into account reasonable cost, often using a multi-level storage system. Depending on the role of the memory in the electronic device system, it can be divided into a main memory and a spare memory, also referred to as main memory and auxiliary memory. When some devices of an electronic device need to load programs or data from memory, such as when the processor is booted, the bootloader needs to be loaded from the memory; for example, an FPGA (Field-Programmable Gate Array) is configured for active loading. When you need to load logic code from memory. In order to prevent the program or data in the memory from being abnormal, lost or damaged, and the device such as the processor or FPGA cannot be loaded normally, the main memory is switched to the spare memory, and the program or data is loaded from the spare memory.

In the related art, there are various schemes for switching between the primary memory and the backup memory. For example, two FLASH boot CPUs (Central Processing Units) are used. When the main FLASH fails to start the CPU, the CPLD will select the backup FLASH and output a reset signal to the CPU to enable the CPU to boot from the backup FLASH. The solution is to use the programmable logic chip to realize the function of starting the CPU system, but the programmable logic chip has high cost and needs to run logic code, which increases development cost and maintenance cost. It is also possible to replace the existing logic chip with a timer to realize the startup switching of the CPU between the main memory and the backup memory. However, this technique is too complicated, and it is difficult to ensure the relationship between the CPU reset timing and the main standby memory switching timing. The CPU has been restarted, but the primary spare memory has not been switched, and the startup cost is high and the reliability is poor.

The above content is only used to assist in understanding the technical solutions of the present invention, and does not constitute an admission that the above is prior art.

Referring to FIG. 1, the hardware involved in the booting device of the electronic device includes a booting system 100, a booting device 700, a first memory 800, and a second memory 900. The booting system 100 includes a control module 200 and a switching module 300. When certain devices of the electronic device need to read programs or data from the current memory, that is, when the boot device 700 of the electronic device is booted, such as when the processor of the electronic device is booted, it is required to be from the first memory 800 or the second memory 900. The boot program is read; when the electronic device is actively read in the FPGA configuration, the logic code needs to be read from its first memory 800 or the second memory 900. The data bus of the boot device 700 of the electronic device, the address bus, and control signals other than the CS signal (Chip Select) are connected to the first memory 800 and the second memory 900. The CS signal output by the boot device 700 is connected to the switching module 300 of the booting system 100 of the electronic device, and then transmitted to the first memory 800 or the second memory 900 of the electronic device via the switching module 300, if the electronic device is from its first memory 800 When activated, the CS signal output by the boot device 700 of the electronic device is transmitted to its first memory 800, and the CS0 signal is valid; if the electronic device is booted from its second memory 900, the CS signal output from the boot device 700 of the electronic device is transmitted. To its second memory 900, the CS1 signal is asserted.

The control module 200 of the activation system 100 of the electronic device transmits its RESET signal (reset signal) to the activation device 700 of the electronic device for resetting the activation device 700 of the electronic device. The CTL signal output by the startup device 700 is sent to the control module 200 of the startup system 100 of the electronic device, and the S1 signal (switching signal) output by the control module 200 is connected to the switching module 300 of the startup system 100 of the electronic device, and the switching module 300 receives the The S1 signal generated by the control module 200 of the booting system 100 of the electronic device is used to control switching between the first memory 800 and the second memory 900 of the electronic device. Whether the electronic device is switched to its first memory 800 or to its second memory 900 can be controlled by changing the level of the S1 signal level. For example, when the S1 signal is high, the CS0 signal is valid, the electronic device switches to its first memory 800, when the S1 signal is low, the CS1 signal is valid, and the electronic device switches to its second memory 900; When the S1 signal is high, the CS1 signal is active, the electronic device switches to its second memory 900, and when the S1 signal is low, the CS0 signal is active and the electronic device switches to its first memory 800. In this embodiment, it may be selected that when the S1 signal is high, the CS0 signal is valid, the electronic device switches to its first memory 800, when the S1 signal is low, the CS1 signal is valid, and the electronic device switches to its second memory. 900.

Preferably, reference is made to Figure 2, which is a schematic illustration of an embodiment of the activation system of Figure 1. The control module 200 of the startup system 100 of the electronic device includes a watchdog module 400 and a trigger module 500, and the like, and the switching module 300 includes a switch module 600 and the like.

The watchdog module 400 of the control module 200 of the booting system 100 of the electronic device is composed of a watchdog circuit, which is a special reset monitoring circuit. The role of the watchdog circuit is to force a hardware reset of the CPU to bring the entire system back into controllable state once the CPU has failed.

The trigger module 500 of the control module 200 of the booting system 100 of the electronic device is constituted by a flip-flop circuit. A flip-flop is a memory cell circuit that operates when a clock signal is asserted. It handles the interaction between the input and output signals and the clock frequency. According to the different characteristics of the logic function, the trigger is divided into RS trigger, JK trigger, T flip-flop, D Several types of triggers. Triggers of the same logic function can be implemented with different circuit structures, that is, the same circuit structure form can form triggers of different logic functions.

Preferably, the trigger of the above trigger module 500 selects a D flip-flop, and the D flip-flop is composed of 6 NAND gates. The watchdog circuit of watchdog module 400 selects SP706R/S/T, its reset pulse width is 200ms (rated value), independent watchdog timer is 1.6s timeout (rated value), debounce TTL/CMOS manual Reset input (/MR pin). The SP706R/S/T pin function table is shown below.

The RESET signal output from the /RST terminal of the watchdog module 400 described above is transmitted to the boot device 700 of the electronic device. The WDI terminal of the watchdog module 400 receives the CTL signal output from the boot device 700 of the electronic device, the /WDO terminal of the watchdog module 400 is connected to its /MR terminal, and its /WDO terminal is connected to the CLK terminal of the flip-flop module 500. . The /Q terminal of the flip-flop module 500 is connected to its D terminal, and its Q terminal is connected to the SWITCH terminal of the switching module 600 of the switching module 300 of the startup system 100 of the electronic device. The IN terminal of the switch module 600 receives the CS signal output by the boot device 700, the OUT0 terminal of the switch module 600 is connected to the first memory 800 of the electronic device for transmitting the CS0 signal, and the OUT1 terminal of the switch module 600 is connected to the second device of the electronic device. The memory 900 is configured to transmit a CS1 signal. The initial state of the signal output from the /RST terminal of the watchdog module 400 and the signal output from the /WDO terminal is a high level, and the initial state of the signal outputted from the Q terminal of the flip-flop module 500 is also a high level.

The watchdog module 400 has no level change in the signal outputted by the WDI terminal within 1.6s, that is, when it does not change from a high level to a low level or from a low level to a high level, the /WDO terminal outputs The signal changes from high level to low level; when the signal output from its WDI terminal changes level, that is, from high level to low level or from low level to high level, its /WDO output The signal stays high. Since the /WDO end of the watchdog module 400 is connected to its /MR side, when it /MR When it is low, it will trigger its /RST output low level and will go high after 200ms. The function of the activation device 700 of the reset electronic device is implemented. Moreover, when the signal outputted by the /RST terminal of the watchdog module 400 is low, the signal outputted from the /WDO terminal is restored from the low level to the high level, and the output of the /WDO terminal of the watchdog module 400 is realized. The process of changing the signal from high to low and then to high.

The /WDO terminal of the watchdog module 400 is connected to the CLK terminal of the flip-flop module 500. If the signal output from the CLK terminal of the flip-flop module 500 changes from a low level to a high level, the Q terminal of the flip-flop module 500 outputs its The D terminal signal, whose /Q terminal outputs the inversion signal of its D terminal. Since the /Q terminal of the flip-flop module 500 is connected to its D terminal, the signal outputted by the Q terminal every time is the inverted signal of the signal outputted last time, that is, the signal outputted by the Q terminal of the flip-flop module 500 is realized. High and low level flip.

The signal S1 outputted by the Q terminal of the flip-flop module 500 is sent to the SWITCH terminal of the switch module 600. When the signal of the SWITCH output of the switch module 600 is high, the signal output by the IN terminal of the switch module 600 is sent to its OUT0 terminal; When the signal of the SWITCH output of the switch module 600 is low level, the signal outputted by the IN terminal of the switch module 600 is sent to the OUT1 end thereof, so when the signal outputted by the SWITCH terminal of the switch module 600 is turned high and low, the CS signal is realized. Switching between the first memory 800 and the second memory 900 of the electronic device is achieved by switching between the CS0 signal, the CS signal and the CS1 signal. The switching between the first memory 800 and the second memory 900 of the electronic device may be from its first memory 800 to its second memory 900, or from its second memory 900 to its first memory 800.

Preferably, referring to FIG. 3, FIG. 3 is a timing diagram of the startup system of FIG.

When the signal output from the /WDO terminal of the watchdog module 400 changes from a high level to a low level, and after t0 (about 1 us) time, the signal output from the /RST terminal of the watchdog module 400 becomes a low level. The signal output from the /RST terminal goes high after a period of t1 (200ms). /WDO returns to high level when /RST goes low. After /WDO changes from low level to high level, the signal output from the SWITCH terminal of the switch module 600 changes from a high level to a low level. After the signal output from the /RST terminal of the watchdog module 400 goes high, the boot device 700 of the electronic device is restarted, that is, the electronic device reads the program or data from the current memory. However, before the boot device 700 of the electronic device is restarted, the first memory 800 of the electronic device and the second memory 900 have completed switching.

Based on the above hardware architecture, an embodiment of a method for starting an electronic device of the present invention is proposed.

The memory corresponding to the startup failure of the startup device of the electronic device is determined to be the first memory, that is, the memory corresponding to the startup device reading program or the data failure of the electronic device is determined to be the first memory.

The above S1 signal is used for the electronic device to switch from the first memory in which it is currently located to the second memory, that is, to switch from the main memory to the backup memory. When the RESET signal begins to take effect, the S1 signal begins to switch from the first memory to the second memory. After the S1 signal is successfully switched from the first memory to the second memory, the RESET signal is deactivated and the electronic device is reset from the second memory. Start its startup device.

Preferably, it may be selected that when the S1 signal is high, the CS0 signal is active, the electronic device switches to its first memory, and when the S1 signal is low, the CS1 signal is active and the electronic device switches to its second memory.

In this embodiment, by switching from the first memory to the second memory according to the switching signal; after successfully switching from the first memory to the second memory, the reset signal is disabled, and the boot device is restarted by the second memory. In this way, material cost, R&D and maintenance costs can be saved by eliminating the need for expensive programmable logic chips.
