Hi,

I am trying to flash basic Led blinking code. During the flashing, I have seen the error which is attached with this forum. I have double checked the connections.

Details of the board: LoRa-E5 Dev Board which has STM32WLE5JC.

Debugger: Segger Jlink

IDE: STM32CUBEIDE

Hi,

Thanks a lot for the support. Am able to flash the code in the Dev Board. The issue here is during configuration for ADC, one of the pins used for JTAG is misconfigured for the ADC and it causes the JTAG not able to connect the board.

Thank you,

Mahesh

Hello @Community member​ and welcome to the Community 🙂

Can you connect the board via STM32CubeProg?

Try with different boards, cables.

Check connectivity options and the jumper position on the board (UM2592: STM32WL Nucleo-64 board (MB1389))

Try Connect Under Reset.

If the problem is not resolved, please share more details about the CubeIDE, Cubeprogrammer version.

I have connected one end of the debugger (j-link) to PC and other end to the STM32WLE5 Development board (LoRa-E5 Dev Board). The connection looks as below. I am using J-link debugger to flash the code.0693W00000aHiY5QAK.jpg

Hello @TGUDL.1 ,

1- Try to test the same scenario with Cubeprogrammer

2- I wonder you to enable low power debug mode and connect under reset as shown in the screenshot bellow:
