One of my systems started throwing debug messages on the LCD during startup .
After some resets it will write assert, after others it will write “can not execute debug command” on others it will run the user code with no notifications at all.
All this with the USB debug cable disconnected.
I want to investigate this a bit more before re-flashing the board.
The odd thing is that in some cases it runs the user app and everything runs properly.
Once in a awhile it thinks it’s connected to a PC with a magical invisible USB cable ;D.
This message is a trap we have in code when things go wrong internally. We would need some details on how are you seeing this so we can track it down and fix it please. Please make sure you have the latest SDK installed on your PC and the latest firmware is loaded on you device before any further testing.
