I am working on i.MX6 Solo board with Yocto OS . The Linux version is 3.14.38 . We made the board to switch on and off continuously several times within some few seconds gap . After 20-25 times of testing the board reboots after the linux login prompt appears or just before that. After reboot the board is stable and no issue further. The watchdog is enabled but I tried after removing it too. The POR signal is going low and the board is resetting. We are stuck up with this issue and do not know how to go forward.
Kindly provide some suggestions to debug and solve this issue.
Thanks & Regards,
