As U-boot tends to be built for the board and is very flexible it is
possible to build it with a zero timeout on the boot prompt so it
becomes impossible to enter interactive mode.
Hi, Lawrence.
Can't help thinking they did that on purpose :-(
When you have it open also look for a JTAG connector, typically a 2*5 or
2*10 pin header as this will be another possible route into accessing
the flash. (Looks as if maybe a 16 pin connector
https://www.etoolsmiths.com/jtag-pinouts-and-connectors-for-powerpc/)
OK + thx for that link.
U-Boot probably has it's own partitions in the flash, commonly a
partition for uboot and a partition for uboot confirguration. But also
has default configuration built in so just erasing uboot config may not
help.
I've attached the boot logs from my 'bricked' SV841DUSBI IP-KVM and a
working SV841DUSBI IP-KVM, which seems to have idenical firmware, and a
diff of the boot logs, showing where the SV841DUSBI IP-KVM goes wrong.
If in touch with startech them ask them whether it has a JTAG port or
what do they use for factory programming. I have a variety of
programming hardware.
My Startech support contact has not relied since I told him I bought the
IP-KVM off eBay, despite Startech's widely advertised lifetime support.
Looking at the boot log the kernel looks OK and it is possibly the root
filesystem that is the problem.
Yes, I think you're right about that.
Thanks for your helpful suggestions,
Tony.
