Hi @vinothkumars 

The demo that if you work with EVS. The DPU is initially given to M4 in the EVS demo, but will be given back to android(AP) when Android starts, you don't need to modify it.

Best regards

Thank you @Harvey021 for the reply,

Actually, we are not using EVS for now. Is it possible to release SC_R_DC_1 to Application Processor as soon as kernel start. 

Because due to this SC_R_DC_0 interface will take time for first boot (more than 2 min) and reboot (30 seconds)

Want to release and use SC_R_DC_1 resource as soon as possible.

Do you have any specific patch or configuration for use this release before RPMSG register (vehicle_rpmsg_m4.c)
