burning firmware onto an ST-Link to burn firmware onto anything else

at least I'm trying to find that out. The clones from aliexpress are supposed to be only able to program st chips. But I want to use it to program some SAMD-21 chips. Never done that as well. So this is a link drop first. Figuring it out for MAC OS.

install open-OCD via homebrew

for unlocking the stm for new firmware go here

install new firmware called cmsis-dap

get this file

https://raw.githubusercontent.com/x893/CMSIS-DAP/master/Firmware/STM32/hex/CMSIS-DAP-STLINK21.hex

install with this line

openocd -f interface/stlink.cfg -f target/stm32f1x.cfg -c "init" -c "halt" \

    -c "flash write_image ./CMSIS-DAP-STLINK21.hex" -c "shutdown"


doing this to flash arturos latest keyboard firmware, had to install arm gcc first. Brew doesn't work as it's not trusted. Downloading here helped.
