Thanks for the fix!
I accepted your SR to Base:System/u-boot. It is on the way to Factory.


I just tested JeOS 2016.03.09-Build5.1, but a reboot does not boot the
system anymore, like before. It tries to boot via the network.

I now have a USB serial interface to connect to the GPIO pins 13 14 and 15.
Will try this and hope to be able to give printenv.

I succeeded in getting the output of printenv after interrupting the U-boot
process using Build389.1, which is working and the non-working 2016.03.09-
Build5.1. It is an attachment, but I am not sure it will get through, so I
also have it appended in this text.

This is where it's broken. The patch I mentioned ealier in the thread
fixed this hickup. To verify locally, try to run

# setenv boot_prefixes / /boot/
# boot

on your device. It should boot now even with the broken image. Once the
updated u-boot is properly checked into Factory (submission is still
pending), new images will get built that have this fixed.

Sorry for the hickup. The patch that cause the breakage is part of a
pretty major rework to enable grub2 and a standard EFI workflow on our
arm images, so that during boot you can choose between different kernel
flavors, edit kernel command lines etc. as soon as your board gets
enabled. It shouldn't have broken the existing boot.scr path, but it
did, sorry again :).
