Fixed this issue -- was a <&uart*> number I missed changing... doh
I can now manually add the device tree : cat /sys/devices/platform/bone_capemgr/slots 0: PF---- -1 1: PF---- -1 2: PF---- -1 3: PF---- -1 4: P-O-L- 0 Override Board Name,00A0,Override Manuf,BB-APA-00A0,Override Manuf,BB-APA-01 How do I bake this into my kernel such that it loads at boot?
