I'm using J-Link debugger to program my STM32F103 MCU, and everything is going fine. However when I disconnect the debugger from the controller board, the MCU doesn't work anymore, even if I reset it.
Could you please give me any hint, what to do to allow my MCU to work without being connected the debugger?
Is your BOOT0 pin tied to ground?
Thank you guys for your fast replies!
Yes, my Boot0 pin is tied to ground, also, I'm using my own hardware, with a modified version of the Blinky program.
Today, I have tried to power the circuit and it works, but this time with the debugger totally disconnected from my board, once I connect the J-Link connector it stops to work, even though the J-Link is not powered (not connected to the USB port)
So I think that the debugger connector has some kind of passive connection that apply a reset to the MCU.
Thank you again for your tips!
