Hi, When I did, mender complained about it : include/config_mender.h:41:3: error: #error CONFIG_SYS_REDUNDAND_ENVIRONMENT is required for Mender to work. Make sure that: 1) All the instructions at https: 41 | # error CONFIG_SYS_REDUNDAND_ENVIRONMENT is required for Mender to work. Make sure that: 1) All the instructions at https://docs.mender.io/system-updates-yocto-project/board-integration/bootloader-support/u-boot have been followed. 2) All required layers are included in bblayers.conf, including any board specific layers such as meta-mender-<board>. Check also https://docs.mender.io/troubleshoot/yocto-project-build for Known Issues when upgrading.
I guess I could disable the check, but even so I'm not sure it would work as uboot.env does not get written ?
