I built a simple test program for userland, which just uses the write() syscall to say hello world. This is statically linked, and it works under a 2.4 kernel. Under 2.6, I get no output. My guess is that an exception is occuring, the signal gets back to my test program, and it is looping. I've written a simple assembly language hello world program which does the exact same thing... write() syscall and I get my hello world. My next task is to get kgdb working on this board so I can do some better debugging, but I was wondering if anyone else has seen this problem, or for that matter whether the SB1 processor support is expected to work at all. Thanks for any help, Kevin -- Kevin Paul Herbert cisco Systems, Inc.
