/etc/fw_env.conf file on TorizonCore has the following:
# emmc-boot0 is symlink to the mmcblkXboot0 # Block device name Device offset Env. size /dev/emmc-boot0 -0x2200 0x2000
however this device / symlink does not exist and hence fw_printenv also fails. If I replace this with the actual device
/dev/mmcblk0boot0 then fw_printenv works. This is in the TorizonCore distro and also my local image built from dunfell-5.x.y.
In the Reference Image (Apalis-iMX8_Reference-Minimal-Image-Tezi_5.0.0+build.3.zip) from the artifact server, this is working as the file has
