Enable Rootfs_AB for multi-spec capsule update

[seeky15]

I have generated my multispec capsule payload like this:
sudo ./l4t_generate_soc_bup.sh t194x
${ToT_BSP}/generate_capsule/l4t_generate_soc_capsule.sh -i ${ToT_BSP}/bootloader/payloads_t19x/bl_only_payload -o ${ROOT_DIR}/bup/bootloader.capsule $SOC

I have added the required lines for out board into the jetson_board_spec.cfg

After updating the bootloader with the capsule update, the rootfs a/b is not enabled anymore:
nvbootctrl dump-slots-info -t rootfs
RootFS A/B is not enabled.

What do I need to set during bup generation, so that it stays enabled?

[seeky15]

Simply need to run sudo ROOTFS_AB=1 ./l4t_generate_soc_bup.sh t194xinstead.

Unfortunately not documented.

hello seeky15,

FYI, we’ve documentation update to add ROOTFS_AB=1 options for generating multi-spec BUP.
please expect next public release will include that.
