Hi @tobiasjaster I don't see the boards/arm/stm32l4/nucleo-l496zg/src/stm32_gpio.c file to support user GPIO on this board, so it needs to be added first. About your question why not use CMSIS or STM-HAL, there is an old thread here about it: https://nuttx.yahoogroups.narkive.com/QxSBuUvM/cmsis In theory it is possible to use some vendor HAL (new Espressif RISC-V chips are done this way), but I think for historic reasons Mr. Greg always developed the MCU support from scratch. You could think this work is very painful (and in fact it is), but that bring a level of similarities among all ARCHes supported by NuttX. Also it forces you to learn more about the MCU low level, so you will really know almost everything about it. -- This is an automated message from the Apache Git Service.
