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.
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

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.
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.
Looking at the boot log the kernel looks OK and it is possibly the root
filesystem that is the problem.

Can you break into u-boot?
Hi, Tom.
Not succeeded yet, but still trying...
If you can get a u-boot prompt then you can probably dump the flash.
>From u-boot, I don't see the normal 'press any key to interrupt boot'
message so you might be out of luck.
I know + that's disappointing :-(
If you can share internals photos and a firmware image then we might be
able to manually flash any spi eeproms. Risky, but might be worth it.
OK, I'll pull it to bits again and have a look.
I've emailed [email protected] and [email protected], asking for help.
Cool,
If you take it a part again please take pictures of everything. Ideally
both sides of boards. It is hard to get part numbers to show in pictures
so writing them down while the board is open can help.
Some times they are really hard to read, so a photo with light coming at
a particular angle can help and sometimes you have to try a range.
I think this board is quite large, I would suggest one front and back
and then the closest shots you can manage of all chips on the board.
