Hello!
I`ve got a J-Link v5 and Segger 408l software installed, and STM32F103RET6 with disabled JTAG interface (by firmware via remap register).
How could I connect debugger for firmware update in this situation?
In the Keil uVision 4 J-Link interface configuration I`ve found interesting option - "connect under reset".
Does that means that debugger should connect to the core just after (or right under) NTRST signal assertion (when JTAG interface being reset and operational)?
Unfortunately, I have no result at the moment. Debugger does not activate NTRST and can`t connect with MCU regardless of reset mode set.
Help me, please.
