Mounriver Studio... anyone with a working setup under linux?

[wilhe_jo]

Hi!

I just want to run the template project for a CH32V307 on my CH32V307V-R1-1V0 board.

After getting the "cannot write to 0x000"-error, I found on the net, that I need to update my the wlink on the board.
That seems not possible under linux, so I fired up a VM with win10, installed the windows version a got a bricked programmer.
2 days of pulling hairs, I got this fixed (see other thread) and now I'm left with libusb bulk-transfer timeouts.

Any ideas?

BTW: I get IDs from the target... so at least some communication works.

A little update... I reverted back to MRS 1.5 by guessing a download link (http://file-oss.mounriver.com/upgrade/MounRiver_Studio_Community_Linux_x64_V150.tar.xz)... that gave me back a working system.
So something is fishy with the OpenOCD they ship with the 1.91 toolchain/1.7 Studio

If someone has some idea how the get the current version running... I'd be glad to hear ideas

I bought PC from Aliexpress with win10 and put Mounriver there. This link:

Also I have old Core2duo with 4 SSD mechanically switched from one system to another (one SSD = one system).

Sorry, but your suggestions are not helpful.

Neither the recommentation to use Win XP in the other thread, nor using a totally outdated system with Windows.
My whole office runs under linux.

The problem seems to be in the software WCH provides.
I had the same issue before with something between 1.5 and 1.91.
The question is, if there's some solution to this.

For now, I reverted back to MRS 1.5 which seems to do.

You don't have to use MounRiver Studio at all, if you don't want. Standard GCC works fine, and you can build your own OpenOCD https://github.com/openwch/openocd_wch

and you can build your own OpenOCD https://github.com/openwch/openocd_wch

That's prebuild binary without linux support, there are some forks made from GPL lettered sources though
e.g. https://github.com/jnk0le/openocd-wch

You can use mainline GCC as Bruce mentioned. If you don't need a debugger, you don't even need OpenOCD either. I use wlink for flashing CH32V30x.

I'm developing in Linux for a ch32v307 devboard, and I've modified minichlink in order to specify the ram/flash split https://github.com/ddrown/minichlink-307

I haven't had luck with wlink, it seems to crash my wch debugger.

I also have a Makefile based template for building C/C++ projects for the 307.

Y 2cent for the cause:
Project with all WCH examples compiling (I test many but many is untested now) https://github.com/martinribelotta/openwch-makefile
Bare metal ch32v307 C/C++ template using cmake https://gitlab.com/eta-for-ci/baremetal-ch32v3xx
RT-threads repository (outdated to main rt-thread repo) https://gitlab.com/eta-for-ci/ch32v307-gnumake

They already posted in other messages the links to openocd and wlink... Both work pretty well
