hi,
i am very intereseted by your custom firmware, but i one of my won't start, itried with differend cable and power supply but it won't start.
Do you know where is the problem

?
Do you think your Firmware is able to awake this cube

?
thank you in advance
Does the power supply shut down as soon as you turn it on? Did fire shoot out the back of the unit?
If the answer to either of these is "yes" then one of the power modules has shorted. I have one on the bench here that was being run in a barn (sigh). The dirt, straw, and whatnot built up on the caps until they overheated resulting in blown FETs and a small pretty plasma ball when I tested the supply off-board.
I can oddly enough fix this.
If it doesn't see the miner and Tarkin's code doesn't get it back online, then the chip overheated and fused the solder underneath. Mess. Can be fixed sometimes, but bit of a bitch on wheels to do.
