   @HecticSalad To use the GPIO demo you need to enable these flags:
   ```
   CONFIG_BOARD_LATE_INITIALIZE=y
   CONFIG_DEV_GPIO=y
   CONFIG_EXAMPLES_GPIO=y
   CONFIG_NSH_ARCHINIT=y
   ```
   
   You will then have these 9 pins mapped to the driver
   https://github.com/apache/incubator-nuttx/blob/master/boards/arm/stm32f7/nucleo-144/src/nucleo-144.h#L183-L203
   
   Here is it running:
   ```
   NuttShell (NSH) NuttX-10.0.1
   nsh> ls /dev
   /dev:
    console
    gpin0
    gpin1
    gpin2
    gpin3
    gpint8
    gpout4
    gpout5
    gpout6
    gpout7
    null
    ttyS0
   nsh> gpio -o 1 /dev/gpout4
   Driver: /dev/gpout4
     Output pin:    Value=1
     Writing:       Value=1
     Verify:        Value=1
   nsh> 
   ```
