I programmed the *.sof file to the board. I physically removed my Deo Nano Soc board from the system. All connections were removed from the board. The D-N-S board was reinstalled into my system which consists of a PCB with LEDs, opto-isolators and connectors to other equipment. The test LED on the board started to blink per the previous code listed when power was applied. The D-N-S board was not flashed after start-up. The board will not operate fully until the *.soc file is flashed. However, the test LED will blink per the code without being flashed.

    Did you previously flash the board before programming the board with the .sof? You may need to erase the flash so it does not have previous programming file on it that may have interfere with the board. I am suspecting this is the case.
