We should add a few details, Pins: P8_11, P8_16, and P8_15 can be recovered, by sticking the wl1835 wifi module in 1-bit mode vs 4-bit mode.. sudo rm /lib/firmware/BB-BBGW-WL1835-00A0.dtbo sudo cp /lib/firmware/BB-BBGW-WL1835-1BIT-00A0.dtbo /lib/firmware/BB-BBGW-WL1835-00A0.dtbo P8_12 = WL1835: mmc2_dat0 P8_18 = WL1835: mmc2_clk P8_14 = WL1835: Wireless enabled P8_17 = WL1835: Wireless IRQ P9_12 = WL1835: Bluetooth enabled Pins: P8_26, P9_30 are "gpio hogged" at startup, not user changeable. Pins: P9_28, P9_29, and P9_31 are used by audio, which isn't actually used, but tied up.. @mark, random thought, do you want to try booting with P9_28/P9_29/P9_31 removed from bbgw.. for example.. https://github.com/beagleboard/bb.org-overlays/commit/502c3d228dd6a6902cc6d7b32014075b7c6b8eb6 Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
