Hi Aaron, Meanwhile, Xiang has merged my pull request. So, to a certain extent NuttX now supports the STM32U5.
Currently, only the SPI and the UART macro are supported I/O wise. If your company needs other I/O, please let me know so that we can coordinate work. I recently started my own small business and would be willing to do some contracting work, if that would be an option for you. Bye for now Michael Am Fr., 11.
