Hello Nguyen Trieu Lang

Are you trying to implement intercore communication among SC3900 cores?

Can you please specify what code have you changed and what is the failure?

hi Lunmin,

I modify source code of dpaa_demo project at :CW_SC_3900FP_v10.8.3\SC\StarCore_Support\SmartDSP\demos\starcore\b4860\dpaa_demo.

Now I can implement intercore communication but it is success only by using dedicate channel. For example ,  if I want to send message from core 0 to core 1. For core 0, i must set qman_fqr_params->channel =1 at function appInitQmanFqrParams.

But if i want to use pool channel , when i set qman_fqr_params->channel = (qm_fq_channel_t)(E_QM_FQ_CHANNEL_POOL1) in both core. it is n't success.

Brs,

Lang
