stlink_gdbserver gdb-multiarch
I'm trying to debug some embedded rust. I was using openocd (12) and gdb-multiarch. I currently using an stm32f3discovery. I've tried C with eclipse Embedded ARM and STM32CubeIDE and while STM32CubeIDE does work (validating my hardware) nothing else works reliably. I have tried using ST-LINK_gdbserver from the stm32cubeide installation with gdb-multiarch which give much the same results as openocd + gdbmultiarch. Below is a run from rust but C gives much the same results:
I start openocd which listens on :3333
I start gdb-multiarch:
$ gdb-multiarch -q target/thumbv7em-none-eabihf/debug/examples/hello -ex "target extended-remote :3333"
Reading symbols from target/thumbv7em-none-eabihf/debug/examples/hello...
