Aah yeah, the silly `distro_bootcmd` will do that.

You could add a `printenv` command before `run uenvcmd; run mender_try_to_recover`, that should at least print it before it proceed.

But you could also just copy the lines that are in `boot.scr` manually one by one if you halt boot

All looks in order,

Can you also run

```auto
setenv mender_boot_part 3
setenv mender_boot_part_hex 3

```

and then repeat the sequence in `boot.scr`. Keep in mind to reset the board once to clear out any modifications done in previous attempt.

You could also try the standalone deployments,

and check the status during each step manually to try to isolate

Came to think of it, above can also mean that U-boot roll-backed the update for some reason (e.g due to failing to load Linux kernel or something like that). So if you can capture the console output for a complete update cycle which fails it might provide additional insights.

Console O/P follows, notes:

- uboot now prints env B4 kernel load
- log starts with rootfs to be updated running and fully booted (third boot)
- firstboot does this: basic N/W config, create dirs…, reboot
- secondboot does this: install + config packages, including mender (which is started), reboot
- third and subsequent boots, fully configured, mender started
- for some reason, altboot run, which may be the smoking gun (bootcount, bootlimit=1).

Log too big for post:

Thanks for the log, this seems to be your problem.

When booting the “new image” you get,

```auto
mount: mounting /dev/mmcblk0p2 on /mnt failed: Invalid argument[ 

```

Which triggers a reboot and then you can see in U-boot that it rolled back because it was not succesful in booting the boot candidate,

```auto

But; /dev/mmcblk0p2 is the pre-update rootfs and, at end is mounted. Whatever happens to /dev/mmcblk0p3 (previous) is the problem…

will scrutinize logfile in more detail…

`mmcblk0p3` was mounted just fine,

```auto
[1.652215] EXT4-fs (mmcblk0p3): mounted filesystem without journal. Opts: (null)
[5.252577] mount_root: mounting /dev/root
[5.259469] EXT4-fs (mmcblk0p3): re-mounted. Opts: (null)

```

This means that you have something (automount service?) that is trying to mount `mmcblk0p2` to `/mnt` which is failing and causing a reboot and hence the failed update.

agreed, leave it with me. Problem starts with invalid fstab, which should disable that automount…

</div>

Need some thought to sort this out:  
In rc.local (@ firstboot - create proper fstab)  
openwrt @ firstboot (before hitting my rc.local, creates fstab (which is incorrect for mender, causing err)  
Need to create proper fstab @openwrt firstboot without disrupting openwrt infrastructure too much…

</div>

stuck here:

do update (p2-\>p3), boot into p3, mount it /root (success)  
…  
mount: mounting /dev/mmcblk0p2 on /mnt failed: Invalid argument

using automount in fstab, since without it, other errs causing reboot  
unmount /mnt/mmcblk0p\* in rc.local (otherwise mender update croaks if mounted)

going take a bit to sort this out - suggestions?

Can you share the content of fstab and rc.local
