Description

TECHNICAL FIELD

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] The embedded hardware system is configured with a power supply pin, a startup pin, a reset pin and other pins affecting the startup timing. The normal startup condition of the embedded hardware system is that the power supply pin, the startup pin, the reset pin and other pins affecting the startup timing of the embedded hardware system need to meet the pre-set startup timing control requirements.

[0004] Due to the differences between individual internal hardware components of the embedded hardware system, if a fixed set of firmware parameters is used to control the startup timing, some embedded hardware systems may fail to start. To solve this problem, the current common method is to set the startup timing to a long enough startup time through firmware parameters before the hardware system is shipped, so as to satisfy that all hardware systems can start. This results in a long startup time and low startup efficiency of the embedded hardware system, and the embedded hardware system cannot be reliably started in the shortest time. In addition, the internal hardware components of the embedded hardware system are also affected by environmental factors (such as high temperature and low temperature) to some extent, resulting in different performances. Even if the same set of firmware parameters is used to control the startup timing of the same embedded hardware system, startup failure may occur under different environments. SUMMARY

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the application belongs.

[0027] Figure 1 is a flowchart of the fast start-up method of the embedded hardware system of the embodiment of the application.

[0028] In combination withFigure 1 The fast startup method of the embedded hardware system in the embodiment can include: S101, preset a minimum reference startup timing according to a basic startup time reference.

[0029] Specifically, for different embedded hardware systems, manufacturers will have a basic startup time reference. According to the basic startup time reference, a minimum reference startup timing can be preset.

[0030] It should be noted that the preset group of minimum reference startup timings is generally an ideal limit startup timing.

[0031] Figure 2 The startup related pin diagram of the embedded hardware system is given. In the actual startup process, the startup controller such as the MCU (Microcontroller Unit) in the Figure 2 communicates with the processor in the embedded hardware system.

[0032] The startup related pins of the embedded hardware system include but are not limited to: power supply pins, reset pins (RESET), output enable pins (EXT_EN), power-on pins (PWRKEY), internal power supply output pins (VCC_PMUIO), startup normal output pins, UART or other communication interface pins, and other pins.

[0033] The MCU controls the related startup pins of the embedded hardware system through corresponding general-purpose input / output ports (GPIO, General-purpose input / output). For example, the power supply pin of the processor is controlled through GPIO3; the reset pin (RESET) of the processor is controlled through GPIO4; the output enable state of the output enable pin (EXT_EN) is detected through GPIO5; the power-on pin (PWRKEY) is controlled through GPIO6; the output voltage of the internal power supply output pin (VCC_PMUIO) of the embedded hardware system is detected through GPIO7; other important pins GPIO2 of the embedded hardware system are controlled or detected through GPIO8; the startup information of the processor is detected through the communication interface 1; and whether the startup is normal is detected through the startup normal output pin.

[0034] As shown in Figure 3 , a startup timing reference diagram is given. In Figure 3 , the startup time of the power-on pin (PWRKEY) is 0.5-6s; the output enable pin (EXT_EN) enables the power supply pin to output a set voltage value for 40-50ms; the reset pin (RESET) enables the embedded hardware system to start normally for 2-5ms.

[0035] For example, if the control time of the power-on pin (PWRKEY) is 500 ms by default, the control time of the output enable pin (EXT_EN) is 100 ms, the control time of the internal power output pin (VCC_PMUIO) is 40 ms, and the control time of the reset pin (RESET) is 100+40+2=142 ms; if the device can be normally started using the default start time parameter, it is the minimum start time, and the corresponding timing is the minimum start timing.

[0036] S102, when the power supply quality of the embedded hardware system meets the set requirement, controlling the start of the start-related pins of the embedded hardware system based on the minimum reference start timing.

[0037] The judgment condition that the power supply quality of the embedded hardware system meets the set requirement is that: The ratio of the difference between the actual voltage value and the theoretical voltage value to the theoretical voltage value is less than the set proportion threshold.

[0038] For example, the set threshold can be 5%, or it can be set according to the actual situation.

[0039] The above judgment condition can be used to judge whether the power supply quality of the embedded hardware system meets the set requirement. Only when the power supply quality of the embedded hardware system meets the set requirement, can it provide a prerequisite for reliable start of the embedded hardware system; if the power supply quality of the embedded hardware system does not meet the set requirement, the power supply of the embedded hardware system is unstable and the embedded hardware system cannot be successfully started.

[0040] S103, judging whether the embedded hardware system is successfully started, if yes, the minimum reference start timing is the minimum start timing; otherwise, adjusting the control time of the start-related pins of the embedded hardware system according to the optimal start timing of the start-related pins until the embedded hardware system is successfully started, and the minimum start timing is determined.

[0041] Specifically, in the case of failure to control the embedded hardware system according to the minimum reference start timing, the control time of the power-on pin is first adjusted, then the control time of the output enable pin is adjusted, and finally the control time of the reset pin is adjusted.

[0042] In this way, the control time of the corresponding pin in the start timing can be gradually adjusted to the minimum according to the start reference timing of the embedded hardware system to meet the conditions of the next stage start, so that the whole start time is minimized, the minimum start timing of the embedded hardware system is found, and the embedded hardware system is reliably started in the shortest time, the start efficiency is improved, and the optimal start timing of the embedded hardware system is adapted to the differences of internal hardware components.

[0043] In some embodiments, in the case of failure of controlling the embedded hardware system according to the minimum reference start-up timing, the control time of the power-on pin is adjusted according to a first preset time increment (which can be set according to actual conditions) until the output enable pin outputs a high level, and the adjustment of the control time of the power-on pin is ended. In this way, the minimum control time of the power-on pin can be found in the control stage of the power-on pin.

[0044] For example, if the embedded hardware system fails according to the minimum reference start-up timing, the control time of the power-on pin (PWRKEY) needs to be adjusted first, which can be increased by 1 ms, i.e., the control time of the power-on pin (PWRKEY) is 501 ms in the first attempt. The MCU detects whether the output enable pin (EXT_EN) outputs a high level through GPIO5, and if no high level is output, it is considered that the start-up fails, and the control time of the power-on pin (PWRKEY) is adjusted again, which is increased by 1 ms, i.e., the control time of the power-on pin (PWRKEY) is 502 ms in the second attempt. The MCU detects whether the output enable pin (EXT_EN) outputs a high level through GPIO5, and the above operation is repeated until the MCU detects that the output enable pin (EXT_EN) outputs a high level through GPIO5, and the time of the power-on pin (PWRKEY) is recorded as T1.

[0045] In the case of failure of controlling the embedded hardware system according to the minimum reference start-up timing, when the output enable pin outputs a high level, the control time of the output enable pin is adjusted according to a second preset time increment (which can be set according to actual conditions) until the supply pin outputs a set voltage value, and the adjustment of the control time of the output enable pin is ended. In this way, the minimum control time of the output enable pin can be found in the control stage of the output enable pin.

[0046] For example, if it is detected that the output enable pin (EXT_EN) is high, the MCU waits for a processor running time T2 of 40 ms, and at the same time, the internal power supply of the processor is detected through the voltage acquisition circuit 2, for example, the output is 1.8 V, which is detected through GPIO7. If the detection is not within the range of [1.8V-1.8V*5%, 1.8V +1.8V*5%], the start-up fails, the MCU adjusts the time T2 again, which can be increased by 1 ms, i.e., the time T2 in the second attempt is 41 ms, and at the same time, the internal power supply of the processor is detected through the voltage acquisition circuit 2, and the voltage output 1.8 V is detected through GPIO7. The above operation is repeated until the MCU detects that the processor outputs 1.8 V through GPIO7, and the time T2 is recorded.

[0047] In the case of failure of controlling the embedded hardware system according to the minimum reference start-up timing, when the power supply pin outputs a set voltage value, the control time of the reset pin is adjusted according to a third preset time increment (which can be set according to actual conditions) until the communication interface or the start-up feedback pin detects that the embedded hardware system is normally started, and the adjustment of the control time of the reset pin is ended. In this way, the minimum control time of the corresponding power supply pin can be found in the control stage of the power supply pin, the minimum start-up time of the entire embedded hardware system is ultimately found, and the minimum start-up timing corresponding to the found minimum start-up time is found.

[0048] For example, if the MCU detects that the processor output is 1.8V through the GPIO7, the MCU controls the reset pin (RESET) to be low for 2ms, and at the same time, the MCU detects whether the processor is normally started through the communication interface or the start-up feedback pin. If the start-up is abnormal, the time T3 of the reset pin (RESET) being low is adjusted, which can be increased by 1ms, that is, the time of the second attempt of starting up T2 is 3ms, and at the same time, the MCU detects whether the processor is normally started through the communication interface or the start-up feedback pin. The above operation is repeated until the MCU detects that the processor is normally started through the communication interface or the start-up feedback pin, and the time T3 is recorded.

[0049] Among them, the cumulative addition of the above T1, T2 and T3 is the minimum start-up time T=T1+T2+T3; the above time unit can be ms, or ns, us, s, etc.

[0050] Due to the differences in capacitance, resistance and chips on each embedded hardware system, the start-up time is inconsistent. By automatically controlling the start-up timing through the MCU, the most suitable start-up time and the shortest reliable start-up time can be found.

[0051] In the case of failure of controlling the embedded hardware system according to the minimum reference start-up timing, when the power supply pin outputs a set voltage value, the control time of the reset pin is adjusted according to a third preset time increment (which can be set according to actual conditions) until the communication interface or the start-up feedback pin detects that the embedded hardware system is normally started, and the adjustment of the control time of the reset pin is ended. In this way, the minimum control time of the corresponding power supply pin can be found in the control stage of the power supply pin, the minimum start-up time of the entire embedded hardware system is ultimately found, and the minimum start-up timing corresponding to the found minimum start-up time is found.
