UPDATE: I wiped the SD card completely and gave it a try: it worked.
Just now getting around to updating bees as well as grains. I rain copy.command to update bees, then I coped the grains files into their appropriate destinations.
However, after launching the Bootloader and selecting the new bees hex file, I receive “WARNING: error parsing hex record!” and “WARNING: scary address!” messages.
What’s up with this? Thanks!
