How to know M4 Core is working?      My board print the following message when running.

[ 38.948625] vehicle_rpmsg virtio0.rpmsg-vehicle-channel.-1.1: rpmsg_send timeout!
[ 40.036617] vehicle_rpmsg virtio0.rpmsg-vehicle-channel.-1.1: rpmsg_send timeout!

Hi Vinoth 

one can look at SDK RPC functions for the timer service in  .. /scfw_api/svc/timer/timer_rpc_clnt.c

Hi Igor,

I able to run timer by calling the following API,

 /* Wait for 2 min */

PRINTF("Wait for 2 min \n");

TSTMR_DelayUs(EXAMPLE_TSTMR, 120000000);
         

But, I unable to give any user input in M4 Console, it's hold the resource until 2 Min.

Will you please provide how start and stop the timer depends upon the user input in M4 MCU demo application ?

Is it possible provide timer based event triggered configuration ?

Thanks & Regards,
