Hi Everyone,
I try to compile a cape but I can't change pinmux, does anyone have the
same situation ?
It's already loaded on SLOT but not doing the job :
root@beaglebone:/lib/firmware# cat $SLOTS
0: PF---- -1
1: PF---- -1
2: PF---- -1
3: PF---- -1
4: P-O-L- 0 Override Board Name,00A0,Override Manuf,cape-universal
5: P-O-L- 1 Override Board Name,00A0,Override Manuf,EBB-GPIO-Example
root@beaglebone:/lib/firmware#
dmesg :
