So the "clock ticks" I would expect from ecos in this case would be maximum the MCK/2 that TC0 supports? And a final question, since the Interrupt model that eCos uses as the documentation says, is based on the ARM model, should I expect that the interrupt model work would be transparent from ecos code?(On the AT91EB40a). -- Before posting, please read the FAQ: http://sources.redhat.com/fom/ecos and search the list archive: http://sources.redhat.com/ml/ecos-discuss
