Can you test if it's the IO board or the BeagleBoner itself that is messed up? I believe the 'boner is the same on the S7 as is was for the S5 and S2 (but someone who can say for sure should verify that). If the IO board is okay, I've got a stack of the 'boners laying around.
Well , I think the IO is dead is one controler , and the BB is dead in the other. Because the effect was not exactly the same.
So I trid to melt the part , and now I have a controller fully ok , and a controller fully dead (with BB dead from one S7 and IO Dead from the other).
The good thing is I have one of the two s7 back in game , but the bad news is I have to get a whole controller unit for the second one now.
Any good deal somewhere ?
I wrote too early , my rebuilded controller did not work for long , after one hour it stopped hashing too. I guess today small unexpected power shutdown got it burned too... ultra bad luck.
It is weird because the s7 is making hot air , but the green blinking led (for hashing) doesn't light..
So I think I still need two controllers ... or one able to drive 6 blades.
Thanks guys
