1f00 1024 mtdblock0 (driver?)
1f01 13312 mtdblock1 (driver?)

Hi samiksha

please run ddr test

https://community.freescale.com/docs/DOC-105652 

and rebuild image with new calibration coefficients found from test.

Probably new images were for other board (like nxp reference board)

or had incorrect kernel boot parameters. One can check it in documentation

Best regards
igor
