Check what runner you have uncommented in .cargo/config:
You need `runner = "gdb-multiarch -q -x openocd.gdb", start a openocd instance:
sudo openocd -f openocd.cfg
and:
cargo xtask mightybuga_bsc example blink # use 'cargo xtask help' for a complete list of options
You need runner = "gdb-multiarch -q -x openocd_just_flash_and_run.gdb", start a openocd instance:
sudo openocd -f openocd.cfg
and:
cargo run
You need runner = "./flash.sh" and:
cargo run
The idcode refers to the chip identification. Real STM32F103C8T6s has idcode 0x2ba01477, the CS32F103C8T6 clone has 0x1ba0147. If openOCD exits with an error like this:
Warn : UNEXPECTED idcode: 0x1ba01477
Error: expected 1 of 1: 0x2ba01477
Update your chip id in openocd.cfg
