Good, loading the correct PRU driver works now. However, now I face another problem: When I try to load a device tree overlay from the command line:
echo cape-unversalh > /sys/devices/platform/bone_capemgr/slots my terminal gets stuck. Running dmesg from another terminal I get: [ 275.976817] bone_capemgr bone_capemgr: part_number 'cape-unversalh', > version 'N/A' > [ 275.976866] bone_capemgr bone_capemgr: slot #4: override > [ 275.976885] bone_capemgr bone_capemgr: slot #4: auto loading handled > by U-Boot Cat reveals: machinekit@beaglebone:~$ cat /sys/devices/platform/bone_capemgr/slots 0: ------ -1 1: ------ -1 2: ------ -1 3: ---l-- -1 4: --O--- -1 I get the same result when disabling uboot overlays in the uEnv.txt Am Donnerstag, 31.
