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 error screenshot.

this is ubootenv.
filename is as follows

rootfs

Hello yangjae lee,
Please refer to the following memory map for T2080RDB NOR flash, rootfs is allocated as 29696KB, however the default rootfs ramdisk image provided in the pre-built image ISO is about 31M, please rebuild rootfs image to reduce the size or build fsl-image-minimal image with "bitbake fsl-image-minimal".
Have a great day,
TIC
