Hi jamesh! I was looking for DSR handling mechanism of the eCos and I had question as the same which you asked almost 7 years before, which you posted at http://sourceware.org/ml/ecos-discuss/2002-09/msg00305.html
My question is the same as at your 3rd statement: > When clock interrupt happens: > 1. Cyg_RealTimeClock::isr() invoked > --> 2. return Cyg_Interrupt::CALL_DSR|Cyg_Interrupt::HANDLED > --> 3. Cyg_RealTimeClock::dsr() invoked(right?? how and where is dsr > called?) > ... > BTW: how the dsr is called after the isr called? who is resposible for this > mechanism? I have read through reply posts to your question, but couldn't find the answer. After Cyg_RealTimeClock::isr() returns > return Cyg_Interrupt::CALL_DSR|Cyg_Interrupt::HANDLED who checks that result and makes DSR to be scheduled next? Can you share your answer if you found it by yourself? Thanking in advance, Nodir. -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
