Chris Garry provided me with a redboot image and the twothreads.out
file that worked on his
e7t. i had no luck with it. i even had a chance to try the files on 2
other e7t's but they showed
the same behavior.
i did some debugging of a simple interrupt prog written in c (without
eCos) and it seems like
the external interrupt that i used doesn't get processed correctly.
the interrupt pending bit is
set but the cpu doesn't vector to the isr. i have to check that out
more carefully tomorrow.

I had this kind of behavior when running the e7t with Angel because the latter starts application programs in user mode. Using Redboot instead of Angel solves the problem.

That could explain it, except that Matt said he tried RedBoot unless perhaps Matt put RedBoot on the board but still used Angel to load the applications?
