Linux upload/debug fails #22

gicking · 2023-03-07T04:02:56Z

First of all thanks a lot for your effort! I very much appreciate it :-)

Unfortunately I still have an issue with upload/debug under Linux (Xubuntu 22.04). Here's what I did:

Install CH32V platform as described here and here -> no issue
Clone PIO examples projects as described here -> no issue
Open example "blinky-none-os" and build -> no issue
Press upload button -> failed with Error: libusb_open() failed with LIBUSB_ERROR_ACCESS
In terminal type lsusb to get WCH-LinkE debugger VID&PID -> Bus 001 Device 007: ID 1a86:8010 QinHeng Electronics WCH-Link
Add the following lines to /etc/udev/rules.d/99-platformio-udev.rules:

# WCH-LinkE
ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="8010", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1", ENV{ID_MM_PORT_IGNORE}="1"

Reboot PC and re-try upload -> failed with Error: unknow WCH-LINK

I tried the above with the CH32V003F4P6-EVT-R0 (1-wire debug) and CH32V203C8T8-EVT-R0 (2-wire debug) eval boards from here. Both boards function using MounRiver IDE under Win10 in a VirtualBox on the same PC. So it's not a hardware or setup issue.

The text was updated successfully, but these errors were encountered:

Seems like I'm not the only one.

Here is a page which explains how to solve this issue. I didn't go through the details, but I hope it helps...!?

maxgerhardt · 2023-03-07T08:48:17Z

I've only tried Linux + WCHLink (not the E version) with a Ch32V307 until now, not yet the WCHLink-E with the CH32V003 or CH32V203 board (although I both have them now :)).

The udev rules definitely and entire bringup (and wireup procedure) definitely need to be documented better, that's on the list for this weekend.

The repo with the OpenOCD from MounRiver sources is really good, thanks for that. But the link doesn't say anyhting baout the "Error: unknow WCH-LINK" error? :(

I'll test this on my WCHLink-E + CH32V{0,2}03 boards today.

gicking · 2023-03-07T09:23:34Z

Thanks already in advance! I'm sure it's just a typo, wrong access rights or something similarly simple...

I found the page with the OpenOCD from MounRiver sources referenced here

gicking · 2023-03-07T10:29:36Z

lsusb yields Bus 001 Device 005: ID 1a86:8010 QinHeng Electronics WCH-Link (without E)

However, the label on both PCB and ESD bag of the debugger states "WCH-LinkE-R0-1v3.FP".

So I figure it's indeed a WCH-LinkE, which is also listed in the WCH-Link manual v1.6

maxgerhardt · 2023-03-07T22:12:47Z

My WCHLink-E is also only appearing as "WCH-Link"

... and I am indeed getting the same error message too.

If I use MounRiver in Windows with the exact same hardware and go Flash->Download, it spews out at least some firmware version

I just sent a support email in regards to it. A smoking gun is definitely that the Windows OpenOCD version is newer than the Linux one.

Open On-Chip Debugger 0.11.0+dev-02415-gfad123a16-dirty (2023-01-03-10:00)

vs

Open On-Chip Debugger 0.11.0+dev-02215-gcc0ecfb6d-dirty (2022-10-10-10:35)

So they probably haven't released an updated Linux OpenOCD version yet.

maxgerhardt · 2023-03-08T06:42:28Z

I got confirmation from support that a new version is coming soon.

Hello, as the printed message shows, the current V160 version of MRS_ ToolChain_ Linux does not support WCH-LinkE with the latest firmware (MRS on Windows platform already supports this firmware version). We will launch the MRS tool chain and debugger software on Linux platform as soon as possible.

gicking · 2023-03-10T06:07:10Z

oh darn! I was hoping for a wrong udev rule or something. Well, guess we have to hope that asap is really soon

martiinezz · 2023-03-12T14:42:28Z

What I do on Linux is build in Platform.io and upload using https://github.com/ch32-rs/wchisp - it does upload elf or bin - all you need is to put board into boot mode. I'm sure you can use it as upload_custom script or so.

maxgerhardt · 2023-03-12T14:44:27Z

We will integrate this natively (tracked in #14) indeed soon. I'm watching the Linux section in http://www.mounriver.com/download on the side.

maxgerhardt · 2023-03-12T22:58:21Z

Just FYI @martiinezz I've implemented #14 now and created the project https://github.com/Community-PIO-CH32V/platform-ch32v/tree/develop/examples/usb-cdc-wch32v307-none-os which uploads fine via ISP and the USB works too.

Though WCHISP does not seem to have the ability to boot the chip into run-application, i.e. when it does a "reset" it still looks at BOOT0 pin state and in my case just ends up in USB ISP bootloader mode again. So after a upload, I physically have to move the BOOT0 jumper back to GND and press the reset button to make the board run the uploaded firmware.

I'm using Like-E on Debian and it seems to be working for me.

What WCH-LinkE firmware version does it show though in MounRiver?

martiinezz · 2023-03-29T19:00:35Z

Awesome :)

maxgerhardt · 2023-04-02T14:12:47Z

The packages were approved in the PIO registry so this should now work out-of-the box. Easiest way to update is to force a reinstall.

rm -rf ~/.platformio/platforms/ch32v
rm -rf ~/.platformio/packages/tool-openocd-riscv-wch

and build again.

Reopen if issues persist.

gicking · 2023-04-02T22:27:29Z

Thanks a lot!!!

I just tried CH32V003 and it works :-) However, I did have to copy ~/.platformio/packages/tool-openocd-riscv-wch/bin/60-openocd.rules to /etc/udev/rules.d/ and reboot. Maybe you can also add that to the installation somehow...?
