There seems to be a problem with the LCD4-00A1 cape overlay. The overlay includes support for four buttons, while the actual board seems to have five, and one of the four GPIO pins configured in the overlay is *NOT* actually used by the hardware (per the schematic).
Before I send in a patch, it seems like this would have been identified and fixed before now. Am I just missing the proper overlay somehow? I am building the kernel using the scripts from (tag 3.8.13-bone68): https://github.com/RobertCNelson/bb-kernel/tree/am33x-v3.8 Details: ======== Per the schematic https://github.com/CircuitCo/BeagleBone-LCD4-RevA1/blob/master/BeagleBone-LCD4-RevA1-schematic.pdf The hardware buttons are: Button : Pin : GPIO -------+-------+--------- Left : P9.15 : GPIO1_16 Right : P9.23 : GPIO1_17 Up : P9.16 : GPIO1_19 Enter : P9.24 : GPIO0_15 Down : P9.30 : GPIO3_16 ...but in the DTS (from tag 3.8.13-bone68) I see: exclusive-use = Only 4 GPIO pins for buttons, and one of them is wrong (P9.21, gpio0_3) bone_lcd4_cape_keys_00A2_pins: Same as above (only 4 pins, and one of them is wrong) gpio_keys { Is correct...lists 5 buttons with the proper gpio pins -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
