You can't use those routines in cyg_user_start() where the scheduler and timer interrupt system aren't running. Those only start after cyg_user_start() returns. Many years ago, there was a "System Startup chapter in the manual that explained that sort of thing: http://ecos.sourceware.org/docs-1.1/ref/ecos-ref/system-startup-cyg-user-start.html But, that seems to be gone now. The info on what you can do from cyg_user_start is now found in the reference manual's "Kernel Overview" Chapter in a section on "Calling Contexts". Unfortunately, the docs don't have any section numbering scheme, so it's rather hard to cite them. -- Grant -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
