Hi @dantzler, I've bricked my K210 based sipeed-maix-amigo many times and it always comes back to life (via ktool). Rumor has it that you have an m5stickV that bricked during a recent flash operation which failed. I'd like to know the current state (still bricked? or since fixed?) and if you'd like help in debugging -- here in public or via dm, as you wish. Happy TGIF, enjoy your weekend. -jd
