Hi all,

Hi Santosh

one can check that power was removed all components on the board in the event of a

processor reset, as it is done in i.MX8M EVK design (with nWDOG U704 (UM805RE))

https://www.nxp.com/support/developer-resources/evaluation-and-development-boards/sabre-development-... 

Otherwise one can try to debug and analyse which component remains in non-reset state, probably

dumping processor modules registers in good and non-working case.

Best regards
igor

Hi igor,

 

         I think it is not an issue with watchdog module and after stopped all services again its not restarting in linux4.14 only.If you take linux4.19 its working properly.

Hi Santosh

could you try to reproduce issue on nxp reference board with

nxp official linux from source.codeaurora.org/external/imx/linux-imx repository

linux-imx - i.MX Linux kernel
