This would be nice :-)
Those pins should be available to you, first test with config-pin: debian@test-bbb-2:~$ config-pin -q P9.21 P9_21 Mode: default Direction: in Value: 1 debian@test-bbb-2:~$ config-pin -q P9.22 P9_22 Mode: default Direction: in Value: 1 debian@test-bbb-2:~$ config-pin -l P9.21 default gpio gpio_pu gpio_pd gpio_input spi uart i2c pwm pru_uart debian@test-bbb-2:~$ config-pin -l P9.22 default gpio gpio_pu gpio_pd gpio_input spi_sclk uart i2c pwm pru_uart If you get something like that, then you can change the pin to gpio via: config-pin P9.21 gpio config-pin P9.22 gpio and access it thru /sys/class/gpio/ P9_21 = /sys/class/gpio/gpio3 P9_22 = /sys/class/gpio/gpio2 IF NOT: Run: sudo /opt/scripts/tools/version.sh and share the output..
