Caution
work in progress - it may contains bugs, unoptimized implementations or stubs instead of real functionalities.
The Yasos.zig project is general purpose operating system for microcontollers. Created in mind to be optimized for resource contrained devices, but with POSIX compatibility and userland which is similar the Linux or Unix operating systems.
Implementation is ongoing on MSPC v2 board. MSPCv2 board is RP2350 custom development board. Project is maintained inside MSPCv2
Currently I am working on experimental revision of board MSPC v2 which contains hardware part to implement external MMU (memory management unit) controller on FPGA for external RAM attached to RP2350.
Zig language is under heavily development, which means frequent changes of standard library and language API.
main branch should be compatible with zig: zig-linux-x86_64-0.15.0-dev.384+c06fecd46
Yasos.zig project requires working arm-none-eabi-gcc toolchain for pico-sdk compilation.
Also python3 is necessary to use pykconfig lib and to convert elf files into yaff.
To configure project call:
zig build menuconfig
Then select Board selection -> MSPC v2 since this is only supported board right now.
After configuration use:
zig build
If you encounter linking issue with ubsan runtime library then make sure that your zig contains fix UBSan configuration
