RAK3172 | STM32 Development Environment | GPIO Toggle and LoRaWAN example issues

LPWAN Modules / EVBs

Hi RAK Team,

We have designed a custom board with RAK3172 chip and I am following the steps as mentioned in RAK3172 Low-Level Development | STM32WL LoRaWAN SoC Firmware Guide using SDK v1.0.0

I have followed the steps and tried the LoRaWAN example which is able to upload via STMCube IDE successfully but I am unable to execute debug configuration. The error that is shown is “_fixdfsi() at 0x8000624”. The radio config files and source file are replaced as per the steps mentioned in the link

I have also tried the simple GPIO toggle from the SDK v1.0.0 bundle example and replaced the source file. I am able to run/debug the code but the assigned GPIO “PA4” in the code doesn’t toggle but always stays LOW as seen from oscilloscope.

Could you please advise on the steps to be able to resolve it?

Hi @gracengeer ,

Issues related to use of STM32CubeIDE like executing debug configuration with ST-link as well as sample codes from ST with their STM32WL SDK folder is not our expertise.

We can help you fully with RUI3 since we developed this framework but for all related to ST SDK as well as their tools, it is best to consult with them directly. We only provide the Radio Files needed so our RAK3172 can be used on their provided SDK.
