@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> ``` You can read a little about the late initialize feature here https://nuttx.apache.org/docs/latest/reference/os/board.html and then the the NSH_ARCHINIT is documented here https://nuttx.apache.org/docs/latest/applications/nsh/config.html?highlight=nsh_archinit#nsh-specific-configuration-settings which calls the late init function for you. Also for your openocd command if you are using a recent build, you can just use the board configuration: ``` openocd -f board/st_nucleo_f7.cfg -c init -c "reset halt" -c "flash write_image erase nuttx.bin 0x08000000" ``` -- This is an automated message from the Apache Git Service.
