This is a new question.


Hi T_Hamdi

Thank you for your response.

I have installed the Zephyr IDE and used the Blinky LED example. The firmware was flashed successfully; however, the LED is not glowing.

I have attached an image for your reference. Please take a look.

Hello @Kumar123,

I see in the image that the .hex file is flashed using the J-Link debugger. Do you have a J-Link connected to the board, or are you using the ST-Link included on the board?
