Hi Benny et al, I'm developing my application on nios2-uclinux environment. I would like to improve media performances by using on-chip-memory instead of external memory. Based on the PJSIP documentation this implementation is possibile by using pj_pool_create_on_buf function instead of pj_pool_create. I tried it as first attempt without setting any memory address: ... char buf[4096]; ... pool = pj_pool_create_on_buf("app", buf, sizeof(buf)); ... status=pjmedia_conf_create( pool,... ... when I execute the application I get the following error: ... 16:04:43.788 except.c !!!FATAL: unhandled exception PJLIB/No memory! Am I missing some additional function? Thanks, Fabio
