Hi, > > As always, check the show-pins.pl output to make sure the mux is right. >
P9.29 / hdmi audio fs 101 B13 fast rx down 3 spi 1 data 0 ocp /P9_29_pinmux (pinmux_P9_29_spi_pin) P9.30 102 D12 fast rx 1 pwm 0 tripzone eqep@48300180 (pinmux_eqep0_pins) it isn't, I think. P9.30 should also be on the spi pin. but when I try to change the pinmux mode: $ sudo config-pin p9.30 spi ERROR: open() for /sys/devices/platform/ocp/ocp:P9_30_pinmux/state failed, No such file or directory Somehow the eqep is grabbing that pin, but I don't know how to change this... > > Who is the clock master in this system? > It's the BB Blue. I think that clock and chipselect work correctly, as I can see them in the logic analyzer. > What is the SPI configuration code like? > 200khz, mode3, 8bits. but right now, my major problem is getting the MOSI pin to work :-) -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
