AM5718: AM5718: low singnal on PORZ can't restart the linux in am5718 plat--2

HI,

I designed the circuit using AM5718 and expect to reset the system using the reset button，the system is linux4.9 which is from the givened SDK: ti-processor-sdk-linux-am57xx-evm-04.03.00.05-Linux-x86-Install.bin；

After the system was running normally, I gave the PORZ pin a low level of approximately 300ms, but the system crashed and did not restart u boot and start Linux.

and When I press the reset button, there is no printout, the board crashes, and I need to power off and restart to work again。

I am currently booting from an SD card.

The SYSCONFIG signal will be used as a GPMC part pin after startup.

My board does not have JTAG function.

Isn't it possible to directly reset the reset pin by introducing a low level for a period of time, lasting for 300ms long enough?

I would like to ask where the problem lies? How to solve this problem? Kindly help me out on this issue.

Thanks and Best Regards
