Hello!
I am asking for help to recover a "bricked" Logitech Sqeezebox Radio.
After having a Squeezebox Radio for a while and being very happy with
it, I bought another one. As I want to use it without a GUI anyway, I
tried my luck buying a "defective" one.
A fast investigation showed that the radio is electrically ok. After I
connected a 3,3V-USB-to-serial converter to the battery-connector I was
able to see that - at least I assume - a firmware upgrade failed. Please
see attached boot-log.
I would like to restore the firmware via the "RedBoot" command line
interface. If I understand
wiki.slimdevices.com/index.php/Fab4_Firmware_Upgrades_and_Recovery
correctly, it should be doable by TFTP. Still, I do not know how to get
the UBI firmware-image, as all images at
downloads.slimdevices.com/LogitechMediaServer_v7.7.2/ have a "bin"
extension.
Unfortunately, I wasn't able to fnd more information on this on the
net.
What I have: a functional Squeezebox (Firmware-Dump)? A Segger J-Link
JTAG interface (Firmware-Dump?), soldering station, masters degree in
electronic engineering...
Thank you very much!
Best regards
Robert
