Hi,
Can you provide me the uClibc config file? I would try to build a toolchain with fortran in crosstool-NG.

Hello, I am not sure what you mean by the uclibc .config file you need. If you are referring to the configuration file used by the cross-compilation tool, we cannot provide assistance with that. The cross-compilation tool arm-rockchip830-linux-uclibcgnueabihf used by luckfox pico in buildroot is provided by Rockchip, and Rockchip has not provided corresponding detailed documentation.

Since in the toolchain directory there is arm-rockchip830-linux-uclibcgnueabihf-ct-ng.config which is the configuration file for crosstool-NG it is clear how the toolchain generation is done. My main goal is not to use another set of libraries (glibc, musl) but just to add gfortran support and to regenerate the toolchain. For now I have a workaround and it works, but I would like to have a fully functional toolchain with gfortran.
If you have the possibility to ask the guys from Rockchip to add gfortran to the existing toolchain (it is enough to check the Fortran field in the crosstool-NG config menu), it would help me a lot. All this about fortran is due to the fact that this SoC has excellent audio potential for HAM-radio applications. I have already managed to test wspr and ft8 decoding and so far it works at a satisfactory speed. Both of these types of communication use very demanding mathematical algorithms and applications for this are written in Fortran
