Comment (by mike@…):
olmari,
Thanks for the response.
The OEM adopted the version of U-Boot that's included with OpenWRT. Take
a peek at /trunk/packages/boot and you'll find version 1.1.4 U-Boot that
was Copy/Forked in 2003 and included in the build system. This leaves a
quandary and I hope you won't take offense as none is intended. What's a
piece of software doing in the repository, receiving commits, included in
nightly builds, being discussed in the forums, documented in the Wiki, and
adopted by dozens of devices as a recovery boot, if it isn't supported?
(lol)
The device is at 115200. I ran the gambit from 300 to 230400 before
walking the code and verifying via a partition dump. Signal trace is what
gave me the final clue as it was full of jitter which led to
"uninitialized UART" results.
