Helping a guy out. Odd behaving board.
With USB connected, all is well with or without battery power.
When USB disconnects (batt still engaged) the saber turns off. At this point, pressing power gives “Font directory not found.” EDIT with non-boosted audio.
Then, if the board is battery power cycled, it comes back with both
“font directory not found”
“SD Card not found.”
If USB is then connected at this stage…the board plays boot.wav and all works fine!?
Never seen this before. It’s like D61 symptoms but not.
