STLINK-V3MINIE - WARN usb.c: skipping ST device : 0x483:0x3754)

[camojoe215]

• I am using a V3MINIE debugger on a STM32G474 target
• Using windows 10
• Using stlink-tools version 1.7.0
• When running st-info --probe

Commandline output:

st-info --probe
2022-09-30T16:19:57 WARN usb.c: skipping ST device : 0x483:0x3754)    
Found 0 stlink programmers

Should be expecting "Found 1 stlink programmer". Not sure why it's skipping considering that there is a definition accounting for PIDs using 3754 in the source code (usb.h). When trying this with a nucleo G474 it works as expected. One possible problem is that the V3MINIE uses usb-c?

EDIT: I tried building the develop branch from source (this has the updated PID missing in the latest release). Building from source documentation isn't working either. CMake complains that libusb library cannot be found and there is no documentation addressing this.

I managed to get this working up to a point - built OK, modified 49-stlinkv3.rules to include

# STLink V3MINIE SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3754", \ MODE:="0666", \ SYMLINK+="stlinkv3_%n"

However, get the following when running st-info --probe

Failed to parse flash type or unrecognized flash type Failed to enter SWD mode Found 1 stlink programmers version: V3J8 serial: 000A0030544B500420343637 flash: 0 (pagesize: 0) sram: 0 chipid: 0x000 dev-type: unknown

How can I help? Happy to provide a MINIE or even attempt a fix myself if there's a guide to where I should be looking to fix this :)

I built the latest code from the develop branch and changed the 49-stlinkv3.rules file as mentioned by stefandz and it worked for me. I guess we should open a merge request for this file adding the missing info. Pull Request already open, see: #1281

Failed to parse flash type or unrecognized flash type Failed to enter SWD mode

I get this when no development board is connected but as soon as i connect my STM32 board the chipid is found and i can program + debug.

@stefandz have you managed to fix your issue ?

I am running in something similar with an ST-Link V3 (idVendor=0483, idProduct=3753).

st-info --probe:

Failed to parse flash type or unrecognized flash type Failed to enter SWD mode Found 1 stlink programmers version: V3 serial: 0023003A3331511834333834 flash: 0 (pagesize: 0) sram: 0 chipid: 0x000 dev-type: unknown

Built from develop branch and supposedly have the correct udev for V3.

Thank you
