Tool/software: Linux
Hello,
We are playing with Processor SDK Linux RT 05_03_00_07 on ICEv2 AM335x board. Now we want to try the examples of PRU. According to the wiki , we have to echo 'stop' to one of the PRU and load a user defined PRU firmware then restart again to test it. But the board always echo back the "permission denied" information so that we can not stop the PRU or load our user defined firmware.
We checked from this bbs and found in one question that maybe means we have to change the device file to put the PRU in user function instead of prueth by default. Am I right?
Could you help to tell us the detail of how to do this test?
Thank you!
