I am working on a PRU example, and when I run it it gives me
prussdrv_open() failed error. Here is the part of the C code that gives me
the error:
prussdrv_init();
if (prussdrv_open(PRU_EVTOUT_0) == -1) {
printf("prussdrv_open() failed\n");
return 1;
}
Here is what I did:
root@beaglebone:/home/xsentius/2# echo PRU-GPIO-EXAMPLE > $SLOTS
root@beaglebone:/home/xsentius/2# cat $SLOTS
0: PF---- -1
1: PF---- -1
2: PF---- -1
3: PF---- -1
8: P-O-L- 0 Override Board Name,00A0,Override Manuf,PRU-GPIO-EXAMPLE
root@beaglebone:/home/xsentius/2# ls
pru_egp_output.bin pru_egp_output.p PRU-GPIO-EXAMPLE-00A0.dts pru_loader
pru_loader.c
root@beaglebone:/home/xsentius/2# sudo ./pru_loader pru_egp_output.bin
prussdrv_open() failed
Any ideas?
