[AM335x warm reset issue] After the warm reset(watchdog reset or WARMRSTn input), the board will halt at RTC

Hi all,

   I met an issue after the warm reset by the watch dog or the WARMRSTn input. 

   After the warm reset, the board will halt in the RTC initialization of the kernel. The SDK version is sdk 6.0.

   Do you have any comments on how to debug it?

Thanks!

Yaoming

    Hi,

    Can you post a dmesg log? Also the console messagese when you execute a watchdog reset.

    Best Regards,
    Yordan
