Adding to this; If I remove the compiled dtbo file from /lib/firmware directory and power-off/power-on the board running manual insert "echo BB-BONE-AUDI-02 > /sys/devices/bone_capemgr.9/slots" gives error write error: File Exists and dmesg shows BB-BONE-AUDI-02 conflict gpio1_19 (#3:BB-BONE-LCD4-01) where I expect it to throw error stating No such file or directory. I validated expected error by trying
echo BB-BONE-AUDI-03 > /sys/devices/bone_capemgr.9/slots which does give expected error of "write error: No such file or directory" On Sunday, March 22, 2015 at 9:57:06 PM UTC-5, Colin Bester wrote: > > In adding Audio Cape (BB-BONE-AUDI-02-00A0) to beaglebone black which also > has LCD4 mounted I receive a GPIO 19 conflict error. > > Looking at the dts file I see it has specified exclusive use for gpio1_18 > and gpio1_19.
