Lora-STM32WL-devkit + STM32CubeIDE = Fail

[JeanBonnot]

Hello everybody,


Devkit is not recognized as genuine ST Device !

OpenOcd give :

openocd -f interface/cmsis-dap.cfg -c "cmsis_dap_vid_pid 0x15ba 0x0044" -c "transport select swd" -c "adapter speed 1000" -f "target/stm32wlx.cfg"

So : STM32WLE/WL5x - Rev 'unknown' : 0x1001

"unknown" is strange, no ?

Then STM32CubeIDE when Run->Debug (F11) give this popup:

"Could not verify ST device! Please verify that the latest version of the GDB-server is used for the connection."


How to check if my  Lora-STM32WL-devkit is genuine or not ?

Thx

This probably means it can't establish connection to the board at all, which I believe is expected unless they improved their support. Last time I checked I couldn't integrate LoRa-STM32WL-DevKit with STM32CubeIDE. I had to compile elf with STM32CubeIDE and then download the elf to the board via OpenOCD (when using USB). Did they add CMSIS-DAP support? Here is where my fears were confirmed in the past:

Did you stumble upon this:

The alternative is using JTAG instead of the USB, make sure the JTAG tool is compatible with STM32CubeIDE.
