Rauc and Yocto on Jetson Nano - Unable to find primary boot slot - yocto

Question

This is a continuation of my other post.
I've managed to create an image with u-boot and rauce.
I've made a simple rauc system.conf:
[system]
compatible=Jetson Nano
bootloader=uboot
#
[slot.rootfs.0]
device=/dev/mmcblk0p1
type=ext4
bootname=system0
#
[slot.rootfs.1]
device=/dev/mmcblk0p13
type=ext4
bootname=system1
[UPDATED]:
Pretty much copy pasted the contrib uboot.sh script.
Then I've added a bb file from here into my bsp layer.
And added rauc to my IMAGE_INSTALL.
When i boot up the nano with my image, rauc isn't working as it should. When i check the status on the service with systemctl status rauc-mark-service-good.service it returns:
● rauc-mark-good.service - Rauc Good-marking Service

Oct 01 07:51:22 jetson-nano rauc[4092]: rauc mark: marked slot rootfs.0 as good
And rauc status returns:
(rauc:4195): rauc-WARNING **: 07:51:46.126: Failed getting primary slot: Failed getting primary slot: Unable to find primary boot slot
Compatible: Jetson Nano
Variant:
Booted from: rootfs.0 (/dev/mmcblk0p1)
Activated: (null) ((null))
slot states:
rootfs.0: class=rootfs, device=/dev/mmcblk0p1, type=ext4, bootname=system0
state=booted, description=, parent=(none), mountpoint=/
boot status=bad
rootfs.1: class=rootfs, device=/dev/mmcblk0p13, type=ext4, bootname=system1
state=inactive, description=, parent=(none), mountpoint=(none)
boot status=bad
So there is no /slot.raucs file and it failed to find primary boot slot.
After that, systemctl status rauc-mark-good returns that the rootfs.0 slot has been marked as good in the end, but systemctl status rauc shows that the boot status is bad.
What am I missing here?

Answer 1

I edited the uboot script to the following:
test -n "${BOOT_ORDER}" || setenv BOOT_ORDER "system0 system1"
test -n "${BOOT_system0_LEFT}" || setenv BOOT_system0_LEFT 3
test -n "${BOOT_system1_LEFT}" || setenv BOOT_system1_LEFT 3
setenv bootargs
for BOOT_SLOT in "${BOOT_ORDER}"; do
if test "x${bootargs}" != "x"; then
# skip remaining slots
elif test "x${BOOT_SLOT}" = "xsystem0"; then
if test ${BOOT_system0_LEFT} -gt 0; then
setexpr BOOT_system0_LEFT ${BOOT_system0_LEFT} - 1
echo "Found valid slot system0, ${BOOT_system0_LEFT} attempts remaining"
setenv distro_bootpart "1"
setenv boot_line "mmc 1:1 any ${scriptaddr} /boot/extlinux/extlinux.conf"
fi
elif test "x${BOOT_SLOT}" = "xsystem1"; then
if test ${BOOT_system1_LEFT} -gt 0; then
setexpr BOOT_system1_LEFT ${BOOT_system1_LEFT} - 1
echo "Found valid slot system1, ${BOOT_system1_LEFT} attempts remaining"
setenv distro_bootpart "13"
setenv boot_line "mmc 1:D any ${scriptaddr} /boot/extlinux/extlinux.conf"
fi
fi
done
if test -n "${bootargs}"; then
saveenv
else
echo "No valid slot found, resetting tries to 3"
setenv BOOT_system0_LEFT 3
setenv BOOT_system1_LEFT 3
saveenv
reset
fi
sysboot ${boot_line}
And it ended up working. Apparently there was some issues with the BOOT_ORDER "system0 system1" in the the uboot script that was somehow not the same as in the RAUC system.conf. When i re-wrote the script, there was no issues and RAUC was running fine.
