Question: Using ch32fun in a GCC make project instead of MounRiver precompiled binaries possible?

[froscon2024]

Is there a simple way to use ch32fun in https://github.com/fossasia/badgemagic-firmware ?
Currently the precompiled MounRiver binaries get downloaded and linked. Then running the make command creates the firmware files.

In here https://github.com/cnlohr/ch32fun/wiki/Installation#linux-with-manual-risc-v-gcc-build-not-recommended you are telling, that its not recommended to use the gcc build. Also 15GB and 1-2 hours of compile time is reported.

What would be the correct way to implement ch32fun into https://github.com/fossasia/badgemagic-firmware to replace MounRiver bin/riscv-none-embed-* files ?
The best outcome would be to not have to download MounRiver any more and just the 'make' command should be enough to build the firmware file.

You would need to port parts that use WCH HAL to ch32fun functions. It's not that hard, but you would need chose one framework over another, I don't think combining them would be easy, pretty or maintainable.

You don't need to build gcc if you're on somewhat mainstream linux distro. All of them should have suitable packages available.

Did you work on this @froscon2024 ? I've been planning on doing this as well here https://github.com/biemster/ch32fun_ch582_ledbadge, and it got close to the top of my list now. (although I'm not planning any compatibility with the BLE app)

If you must use a precompiled GCC, X-PACK's RISC-V GCC works perfectly well. https://github.com/xpack-dev-tools/riscv-none-elf-gcc-xpack/releases/tag/v14.3.0-1 and is roughly 300-400MB.

@froscon2024 the build in biemster/ch32fun_ch582_ledbadge is progressing quite nicely, this would be a great moment to join in if you are still considering this. If not I think we can close this issue.

That is great! Is your port already usable? A binary release would be great.
Could you also make a PR to avoid any future changes like this recent one? fossasia/badgemagic-firmware@13fcf92

My firmware is not really a port, it does not have any of the bluetooth stuff yet, and when I get to that it will likely not be compatible with the original app.
There is another fork of my code already, which is actively developed as well: https://github.com/hamish-milne/ch32fun_ch582_ledbadge

That said, my version is quite usable already with a nice python gui to draw on the badge. However, it does not keep the framebuffer after disconnecting USB, so it is definitely not done yet.

Can this be closed?

Can this be closed?

Yes, @froscon2024 is aware of Hamish's and my ports, and a ticket is opened in the fossasia repository asking if there is interest in a port to ch32fun. This can be closed.
