Success!

FriendlyELEC NanoPi R1 is now Mender-capable. I am able to update rootfs with Mender Artifact, and also verified automatic rollback with faulty Artifact upload.

https://tracker.mender.io/browse/MEN-3970 was the cause of the failure, but was fixed in 2.3.1 (and 2.4.1). As mentioned in previous post, I need to use 2.3.1 because of Ubuntu 16.04. and libssl1.0

Final fixes that made everything work:

  • Specified mender-client version in mender-convert: MENDER_CLIENT_VERSION="2.3.1"
  • Some fixes to MENDER_LOAD_KERNEL_AND_FDT to ensure reboot (mender_try_to_recover) on dtb/kernal load failure.

The tinal MENDER_LOAD_KERNEL_AND_FDT looks like this:

# define MENDER_LOAD_KERNEL_AND_FDT                                                         \
    "if test \"${fdt_addr_r}\" != \"\"; then \n"                                            \

    "else \n"                                                                               \
