Hi, i have recently purchased an STM32F746G-DISCO.

i am very new to STM and compontents, but my manager would like me to try and build an interest with it. I followed a tutorial online, and i have followed the exact routes but i keep getting this error when debugging

video here (Get started with STM32 microcontroller programming)

Error in final launch sequence:

Failed to execute MI command:

target remote localhost:61234

Error message from debugger back end:

localhost:61234: Connection timed out.

Hello @JLythgoe​ 

It will be better to share the screen shot of the debugger settings. It will help to understand the issue.

Try erasing the flash using STM32Cubeporgrammer, and make sure to activate the gdb server log in the "Debugger" tab of your debug configuration, this may help to resolve the issue.
