Problem in Root File System Mount

Hi 

We are trying to do a secure booting in T2080RDB-PC.

 

 

We saved the image and csf header in NOR Altbank(vbank 4) and confirmed that validate part(esbc_validate) print 'Successful'

However, root file system is not mounted. Can you find answer to this question?

 

We attach our consol , ubootenv, and the filename which we used for the secure booting demo.

 

In addition, we trying to change ubootenv, but confirmed that secure u-boot dose not support saveenv.

 

Thank You.

this is ubootenv.

 

filename is as follows

 

U-boot
u-boot-secure-boot-2016.09+fslgit-r0.bin

 

rootfs
fsl-image-core-t2080rdb-64b-20180717052401.rootfs.ext2.gz.u-boot
