How to unbrick a dead XIAO using ST-LINK and OpenOCD

Products & Technology XIAO

Hello and thanks for the quick reply :slight_smile:

  1. I haven’t really gotten to upload a sketch. I only tried flashing the bootloader with both “program … verify” (from this guide) and “flash write_image …” (from How to unbrick a dead xiao using raspberry pi [ GUIDE ][openocd]).
  2. The orange LED doesn’t turn completely off, as in a blink sketch. It brightens and darkens but it’s not as slow as when entering bootloader mode with the other XIAO I have. Actually it’s much quicker (maybe OSC malfunction?).
  3. The XIAO doesn’t appear in Device Manager.
