Nucleo-WL55JC1 Debug Error

[jlaiosa]

I am trying to debug code for Nucleo-WL55JC1 board using sample code from the STM website.  It is the LoRAWAN_End _Node.  I complies fine and creates .elf file.  However when a try do download with the STM32Cube I get the following error:

An internal error occurred during: "Launching LoRaWAN_End_Node".
'com.st.stm32cube.ide.mcu.toolchain.IToolChainInfoProvider[] com.st.stm32cube.ide.mcu.toolchain.ToolChainHelper.getToolChainInfoProviders()'

Thanks for the help.

Hello @jlaiosa 

Please provide more details: STM32CubeIDE version, Java runtime version, exact steps you perform when launching debug, 

Make sure to use latest releases of STM32CubeMX/CubeIDE.

Perform a Project > Clean to remove all build artifacts, rebuild the project fully. Then try launching the debug session again.

If you import the project, follow this article and make sure to use the latest release of STM32CubeMX/IDE as contains limitations fixes: How to import STM32CubeWL repository projects onto different packages
