Hi Santosh

one can try to reprogram image (as it can be corrupted for example due to sudden power off)

with GitHub - NXPmicro/mfgtools: Freescale/NXP I.MX Chip image deploy tools. 

Also may be recommended to retest memory with i.MX 8M Family DDR Tool Release 

please be aware of fix-derating-conflict-issue-L4.14.98_GA2.0.0.patch,

https://community.nxp.com/thread/525707 

its  software workaround has been integrated into the BSP

GA release imx_4.14.98_2.0.0 and latest  Register Programming Aid (RPA).

Best regards
igor

Hi igor,

I had tried re-flashing the board but still the same issue i am getting. I have tested all our application with 4.14.78 version, any other workaround ?

Since its difficult to go for L4.14.98 version

Note: I have tested with new board the image works fine

Hi Santosh

one can consider mechanical or ESD damage and try to resolder or change chip.

Best regards
