OpenOCD "Dropped 'gdb' connection"
Hello All,
I am attempting to establish connections with my STM32H753I-EVAL2 evaluation board through OpenOCD on Eclipse.
For my OpenOCD config options I am using the board script designated for my board;
-f board/stm32h7x3i_eval.cfg
Every time I run this I get an error in final launch sequence:
Error message from debugger back end:
Load failed
Failed to execute MI command:
-f board/stm32h7x3i_eval.cfg
Error message from debugger back end:
Undefined MI command: f
Undefined MI command: f
Failed to execute MI command:
load C:\Users\user\eclipse-workspace\blinky\Debug\blinky.elf
Error message from debugger back end:
Load failed
Load failed
With a console output as follows:

I can at least tell that the debugger is talking to the board because whenever I run the debugger it interrupts the program currently on the evaluation board. I haven’t been able to move past this point however. Can someone please tell me what it is I am doing wrong?
