    Anyone else having boot problems with their run-dmd? About 9 times out of 10, it will not boot. Never gets the blinking red light on the board. But, if I remove the SD card and reinsert it shortly after I power it on, most of the time it will boot up. Once running, it stays running. I have tried reflashing the SD card. Any suggestions?

    Quoted from Limpan:

    Hi Mike,
    Torbjörn saw this post and contacted me. He says that it's a very rare problem, and is caused because the capacitance on the C5 capacitor is not sufficient. The problem can be fixed by soldering a "10uF tantalum capacitor" parallelly on the C5 (on the solder side of the Run-DMD).
    Torbjörn also says that you can return the Run-DMD to him for a repair if you don't want to do the soldering yourself. Send me a PM if you want to solve the issue by returning it.

    Thank you and tell Torbjörn thanks. I just ordered the expansion board so I'll wait till I get that to try the fix. I'll let you know if that does the trick.
