Tool/software: Linux

Hello,

I am testing PRU lab_6 on BeagleBone Black: ' Blinking LEDs with RPMsg from  Linux User Space'. 

It is working if I load the execute file (*.out) for the first time. If I load other execute files (other lab's examples) and then load execute files of lab 6.

It does not work. (echo "b" > /dev/rpmsg_pru30  does not make LED blinking).

I need to reboot the board to make lab_6 working again. What is problem? Is there any command to restart remoteproc and rpmsg instead of reboot the board?

My testing command:

echo 'PRU_RPMsg_LED0.out' > /sys/class/remoteproc/remoteproc0/firmware

echo 'PRU_Halt.out' > /sys/class/remoteproc/remoteproc1/firmware

echo 'start' > /sys/class/remoteproc/remoteproc0/state

echo 'start' > /sys/class/remoteproc/remoteproc1/state

echo "b" > /dev/rpmsg_pru30 

I am using SDK vesion: ti-processor-sdk-linux-am335x-evm-05.03.00.07

Thank You
