[STM32L471RG]: STLINKV3 : can't flash the device. Programmer not supported ?

[Sazerac4]

• [X] Programmer/board type: STLINK/V3 (STLINK-V3PWR)
• [X] Operating system an version: [Ubuntu 22.04.4 LTS]
• [X] stlink tools version : [v1.8.0] installed from release artifact : stlink_1.8.0-1_amd64.deb
• [X] Command: st-flash --reset --format=ihex write ./program.hex
• [X] Target chip : STM32L471RGT6

I can't flash the microcontroller. It works with my stlink-v2.

Command line output:

st-flash 1.8.0

Notes:

• I have modified my udev rules, it is seem the product id was not present. The programmer is not supported ? The new entry added:

  SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3757", \
  MODE:="0666", \
  SYMLINK+="stlinkv3_%n"

• Library libusb (dpkg -l libusb-1.0*)

ii  libusb-1.0-0:amd64     2:1.0.25-1ubuntu2 amd64

Expected/description:

Uploading the firmware is done without any problems

@florrant Thanks for putting this up. As to my knowledge this model is not yet supported by this toolset. Could you make it work based on the changes above? If so, please submit a PR to the testing branch.

Sorry for the misunderstanding. Adding the udev rules wasn't enough to get the device working. I also tried on a Debian 12 without success (same error message).

Edit: Debugging with openocd/st-link work well with this programmer
