Uploading and Debugging for e505 fails with OpenOCD

[MarvFPV]

Hiya, am getting an issue where i can't seem to get opencd to work on a gd32e505re.

This is the error message:

I tried manually adding the gd32e50x.cfg from here but that gives me this error message:

For reference, this is what my env looks like:

[env:genericGD32E505RE]
board = genericGD32E505RE
framework = spl
upload_protocol = cmsis-dap
debug_tool = cmsis-dap

Any input on what i'm doing wrong?

[maxgerhardt]

Not good at all. What's your full platformio.ini? The config you show is at least missing platform = ...

You may also be running an old version of it, in which case I'd recommend the simplest update / reinstall way of deleting C:\Users\<user>\.platformio\platforms\gd32* and rebuilding.

[MarvFPV]

I installed everything a good... 3 weeks ago. but yea, i'll retry. With this chip i'm still dabbling around in the blinky example so the platform is set further at the top in the file😅

[MarvFPV]

Update, same issue after reinstalling (and removing my "custom" .cfg file)

[maxgerhardt]

I'm having the feeling the wrong OpenOCD version is used. I need to check some things.

[maxgerhardt]

The latest published version does indeed not have a gd32e50x.cfg. This likely means I screwed up and haven't yet published the latest version into the PIO registry. I need to double check this on my computer later.

[maxgerhardt]

Ha. The last OpenOCD build of us seems to still be at

https://github.com/CommunityGD32Cores/pre-releases/releases/tag/test

For Windows, please download https://github.com/CommunityGD32Cores/pre-releases/releases/download/test/xpack-openocd-0.11.0-3-win32-x64.zip

Go to C:\Useres\<user>\.platformio\packages\tool-openocd-gd32. Delete all files except the package.json. Then extract the above zip file in the folder. Does it work now?

[MarvFPV]

almost, after also not deleting the .piopm file^^

I can flash code now but debugging using cmsis-dap still does not work. i get a unable to find a matching CMSIS-DAP device error.

[MarvFPV]

Interesting, after trying a second time it works. flashing also doesn't seem to always work... probably wiring issues... i'll play around a bit more and report if i find a pattern.

[maxgerhardt]

If upload_protocol = cmsis-dap does not work consistently, does upload_protocol = gdlinkcli work? This uses the original GigaDevice upload tool. (But no debugging possible with that tool)

[MarvFPV]

so far, the cmsis-dap has worked fine(after that initial hiccup).

[MarvFPV]

@maxgerhardt last question(ish), do you have an estimate when the changes will be added to the release version?

[maxgerhardt]

I'll be publishing the up-to-date packages today, but that just sends them in "for review", after which by experience it'll take 1-2 weeks to appear in the PIO registry.

Please update OpenOCD to 0.12.0, current version 0.11.0 failed to upload on my cheap Chinese dap debugger mine work on upstream OpenOCD 0.12.0 (installed from scoop) and while with gd32-openocd i got this

The platform mostly uses STM32 scripts anyways for GD32. Can you manually overwrite the files in C:\Users\<user>\.platformio\packages\tool-openocd-gd32 with your 0.12.0 version?

[josedelinux]

Yeah, it works when I overwrite the bin directory with binaries copy from tool-openocd thanks
