Pogo 02 not booting correctly (4 replies)

Hi,

I wanted to update to the latest u-boot via http://forum.doozan.com/read.php?3,12381
but it seems I messed up in the B. Flashing default u-boot envs image part...

The serial console states:
U-Boot 2016.05-tld-1 ...
...
Hit any key to stop autoboot: Timer from 10 to 0

When I don't abort it the last lines in the console are
loading uImage ...
** Bad device usb 0 **
loading uInitrd ...
** Bad device usb 0 **
loading DTB /boot/dts/kirkwood-pogo_e02.dtb ...
** Bad device usb 0 **
Wrong Image Format for bootm command
ERROR: can't get kernel image!

With no stick attached.

When I abort the autoboot I get directly
to

How do I get into recovery mode, fix what's wrong and install
debian from scratch now?

The rescue system should be this: http://forum.doozan.com/read.php?4,3896
