OK, so let's say I have a version 4.4.30-ti-r64 kernel, and I get this after boot: debian@BBG2:/sys/devices/platform/bone_capemgr$ 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 According to this (I think), https://github.com/beagleboard/bb.org-overlays I should be able to remove slot 4 by: sudo sh -c "echo '-4' > /sys/devices/platform/bone_capemgr/slots" But that doesn't work, and there is all sorts of mayhem, including this from dmesg: [ 251.257614] Unable to handle kernel NULL pointer dereference at virtual address 0000000d So, the question is, what is the proper procedure for removing a universal overlay, and then putting in a different one? The config-pin utility is capable of adding an overlay, but can it remove one???
