Subject: Re:[ECOS] Re: arm evaluator e7t hangs when executing example progs/tests Date: Thu, 17 Apr 2003 00:07:55 +0200 From: "Matt Kober" <mattkober at web dot de> To: "JonathanLarmour" <jifl at eCosCentric dot com> CC: ecos-discuss at sources dot redhat dot com
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.
