RedBoot(tm) bootstrap and debug environment [ROM]
Non-certified release, version UNKNOWN - built 13:49:51, Dec 17 2004
Platform: Blue_5g (MIPS32 4Kc)

Built in 2004 implies more recent sources. Unfortunately RedBoot kept the
(C) up to 2002 right till September 2004, even though it shouldn't have.
However, the last RHEPL licensed sources in CVS were in January 2002, and
from http://ecos.sourceware.org/ml/ecos-patches/2002-11/msg00082.html
Xavier Debreuil sent his sources in November 2002, and those contained GPL
headers, not RHEPL. So I think it's safe to assume they are GPL'd for now.
I know you are entitled to the very sources used, but perhaps the files in
the above link are sufficient for you to get on with what you want to do?
I will check and see if there is any other information I can find in the
ROM image, but I cannot get it to stop at a command prompt, it just
ignores ^C and proceeds to boots Linux.
Ah, the GPL doesn't cover that :). If the Linux is also locked down, you
might need JTAG, or make some hardware mods so you can reprogram the
Flash, before you have the ability to do anything. Indeed, that would be
the case even if Inventel were freely giving out their sources.
Just had a 'quick' read of the old RHEPL license and section 3.2
"Availablilty of Source Code" suggests that I should still be able to
get a copy of the source as thay have made an executable version
availble.
Yes.
I will do things the 'old' way and write them a letter.
Any thoughts on how to 'break' into RedBoot while running Linux, or how
to change the boot up delay or other saved RedBoot options ?
Once Linux takes over, RedBoot is out of the picture. The boot up delay
and script is probably in Flash. You'd need to fiddle with RedBoot's
fconfig area from Linux if you can. If you can't, then it's JTAG etc. as
above.
