Hi @mwachs5,
Thank you for your reply.
Yes, the parameters are correct. I have selected the same SPIFlash paramaters.
I have done Built-in-self test on board before flashing and the board seems to be working fine.
The problem might not be with .mcs file because i have checked sha1sum of the files as suggested by @mhamrick , the values are matching. Also I have tried flashing different .mcs files and I’m getting same error.
Need some help to solve this problem.
