Hi,
As you know, I accidentally 'bricked' my Startech SV841DUSBI IP-KVM
attempting to upgrade the firmware using the built-in Web GUI and
despite the best efforts of Startech product support they can't help me
to reload the firmware, which means my IP-KVM is now 'bricked' :-(
However, I connected an RS232 null-modem to the DTE serial port of the
IP-KVM to see if the Startech Linux controller outputs any diagnostic
information - It does, and and I captured the Linux kernel boot log
attached below.
Unfortunately, Linux does not boot successfully because the image is
corrupted...
Does anybody know if the version of U-Boot installed on this board can
be used to reload the Linux firmware image over the serial port?
I've not found a way of interrupting the boot to get interactive control
of U-Boot. Normally, you just press a key within the first few seconds,
but that doesn't seem to work on the board in my bricked IP-KVM...
Thanks,
Tony.
