Do you use LS1043ARDB demo board?

 Which version LSDK do you use? Do you use LSDK 20.12?

We do not use CPLD in our board。The reset circuit we refer to FRWY-LS1046A-PA-DF。

LSDK version is 1909。

You can refer our circuit blow。

I did reproduce this problem on LS1043ARDB with LSDK 1909 images.

This problem should be caused by the improper hardware design on your custom board.

Please ask the hardware team to review your hardware design from https://community.nxp.com/t5/Layerscape/LS1043A-can-not-reboot-watchdog-can-not-stop/m-p/1297698#M82...
