Hi, I started testing NuttX on Raspberry Pi Pico board, using FreeBSD as host for building. I was able to build NuttX using all configuration files for this board (but one - nshsram, it does not finish, but I don't care about it for now). All those configurations use default UART placement (pins 0, 1).
These pins are not available on 01space board RP2040-0.42LCD, so I changed UART placement to pins 28, 29 running 'make menuconfig'. This way, .config in NuttX working/build directory is modified, and resulting binary (or uf2 for this board) file works as expected. This file, however, gets deleted when running 'make distclean' for different build. Thus I run 'make savedefconfig', altering defconfig file in working directory. This gets deleted on 'make distclean' as well, so I manually created new directory, where I copied defconfig file - boards/arm/rp2040/raspberrypi-pico/configs/nsh_28_29, and now my config is listed in 'tools/configure.sh -L' output, so I can use it as any other config file. So my questions now - is this intended way for saving and reusing config file? While it works for me, I'd like to have my configs separated from standard source files, maybe as third parallel directory to standard nuttx and apps, with ability to see them in 'tools/configure.sh -L' output, and using my configuration with 'tools/configure.sh <my_config>'. Any hints for this one? Regards, Milan
