Hi All,

VFS: Cannot open root device "ram" or unknown-block(1,0)
Please append a correct "root=" boot option; here are the available partitions:
1f00 1024 mtdblock0 (driver?)
1f01 13312 mtdblock1 (driver?)
1f02 2048 mtdblock2 (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
