Enabling SPI0 on P9 header

[ferdster]

Hi,

Using "Debian 9.3 2018-01-28 4GB SD IoT" on a Seeed Studio BBGW, how do I enable SPI0 on the P9 expansion header? Specifically, having trouble changing modes of P9_17 and P9_22.

root@beaglebone:~/beaglebone-universal-io# ./config-pin P9_17 spi

[ 9965.384388] bone-pinmux-helper ocp:P9_17_pinmux: Failed to find state spi

bash: line 0: echo: write error: No such device

Cannot write pinmux file: /sys/devices/platform/ocp/ocp:P9_17_pinmux/state

root@beaglebone:~/beaglebone-universal-io# ./config-pin P9_18 spi

root@beaglebone:~/beaglebone-universal-io# ./config-pin P9_21 spi

root@beaglebone:~/beaglebone-universal-io# ./config-pin P9_22 spi

[ 9979.783283] bone-pinmux-helper ocp:P9_22_pinmux: Failed to find state spi

bash: line 0: echo: write error: No such device

P9_17 Mode: default Direction: in Value: 0

root@beaglebone:~/beaglebone-universal-io# ./config-pin -q P9_18

P9_18 Mode: spi

root@beaglebone:~/beaglebone-universal-io# ./config-pin -q P9_21

P9_21 Mode: spi

root@beaglebone:~/beaglebone-universal-io# ./config-pin -q P9_22

P9_22 Mode: default Direction: in Value: 0

Thanks.

Oh don't do that... config-pin was forked a while back and is already
pre-installed. By using that old version, nothing will sync up..
