Sounds impossible... But #Arm's #SWD Protocol (to flash and debug firmware) runs just fine on #RaspberryPi's #SPI port... No need to bang out bits slowly and unreliably over GPIO! It's the reason why #PineTime fans @PINE64 can debug firmware with #VSCode today. Hmmm if only somebody had discovered this much earlier... 🤔 https://firstname.lastname@example.org/openocd-on-raspberry-pi-better-with-swd-on-spi-7dea9caeb590?source=friends_link&sk=df399bfd913d3e262447d28aa5af6b63
