That flash read image error does not look good; it essentially means communication with flash is kaput. Can you expand a bit on what board this is and how you use it? (Schematics would be welcome.)

Also, you may want to check if your module uses XMC flash and has status bit corruption, it's a known issue.

Thanks for reply,
We are using readymade board on which esp32 is mounted, worst part is we are not having schematic for this, so not able to share it here.
all in all, we are getting this error as soon as we give power to board, this is observed after half an year since the board was fitted on field and now continuously getting this error logs, does this error means flash address corrupt, or flash itself is corrupt

Can't really say. Can you use esptool.py to read out the full flash, see if that succeeds?
