Pogo dead after uBoot update? (1 reply)

Hi all,

I wanted to update my Pogoplug (pink E02) from "Debian-3.17.0-kirkwood" to the latest version. Before installing new USB Debian rootfs I wanted to update uBoot to actual version.
I used following instructions from a german forum:

cd /tmp
wget -c https://www.dropbox.com/s/0jkzjbryiz9qmbw/uboot.2016.05-tld-1.pogo_e02.bodhi.tar
wget -c https://www.dropbox.com/s/4smmw2wr4ugayz9/uboot.2016.05-tld-1.environment.bodhi.tar
tar -xf uboot.2016.05-tld-1.pogo_e02.bodhi.tar
tar -xf uboot.2016.05-tld-1.environment.bodhi.tar

# flash new uboot:
flash_erase /dev/mtd0 0 4
nandwrite /dev/mtd0 uboot.2016.05-tld-1.pogo_e02.mtd0.kwb

# flash new uboot envs:
#(The MAC address will be set to a valid randomly generated local address.
# you can change it later in debian)
/usr/sbin/flash_erase /dev/mtd0 0xc0000 1
/usr/sbin/nandwrite -s 786432 /dev/mtd0 uboot.2016.05-tld-1.environment.img

The USB Thumb with old Debian rootfs was plugged in. After Pogo reboot the LED is fast blinking green (~20sec) and than changing to fast blinking orange. The LED do not stop blinking. If I detach the USB thumb the LED is also blinking like with it.
No chance to SSH. I have a USB-2-serial cable, but I am not sure what to do.
Any suggestions that might help me? Thanks!
