I have an LPC1115 development board and can debug and upload code as you would expect.
I can disconnect a debug session and the code is running.
If I unplug the MCU in again it will not run the code. It lights the on board rgb LED a color (not sure if if its the same color each time, I think it is).
Here is the project repo.
We have never been able to get the board to power on and run the code. This is a big deal. Does the processor need to be reset? Or is the code not uploaded properly?
