Right now, not many changes needed to make pjsip compiles and run in Blackfin. However, because the current pjsip port to Blackfin is still unstable, it may require changes in pjlib. > 2) how much memory does the linix on the card leave for PJSIP development? I haven't 'cat /proc/memory'. I'll let you know once I'm at home. > 3) Audio: Is all incoming and outgoing stored on the card only? There's an audio expansion card (ad1836) to support audio in the blackfin bf537 stamp board that I'm using. I haven't work with the sound yet because even pjlib test is still problematic at the moment. Anyway, you have to 'modprobe' the driver to make the sound work. Ofcourse it won't be needed if you build it into the blackfin uclinux kernel :).
