Hi Jemish
for that issue one can try latest silicon revision MIMX8MQ6DVAJZAB, try to
add pause between power off and power on event, to verify that all power supplies
were fully discharged.
Best regards

Hi Igor,
Thanks for you reply!
This product is already in market so we can not try new revision.
Regarding your suggestion to add pause between power off and power on can you point out some file /function in code so that I can add and verify.
Thanks,
Jemish
Hi Igor,
Do you have any suggestion for this issue?
Is there any status register (DSI or ELCDIF controller) which will reflect out of sync video in register bits.
It will help us to understand cause for this out of sync.
Thanks,
Jemish
Hi Jemish
I believe there is no software solution. For register settings one can try
to print DSI or ELCDIF controller registers in both good and bad cases.

Hi Igor,
I dumped eLCDIF and DSI registers in good case and bad case but didn't found anything useful. Unfortunately there is not error message for such behavior that could lead to root cause. In our product we added uboot logo support with help from NXP. After that we started seeing this issue. Before that we didn't observe such issue. Can you give some suggestion based on that?
Thanks,
Jemish
