Can someone possibly assist me? I have 3 cards that refuse to start hashing. I tried connecting 1 card at a time operating status goes from running to stop before it starts mining. Only 1 card out of 4 works, if i connect it alone it stays running and starts to mine. If i connect it with any or all of the other three cards, operating status goes from running to stop before any minimg takes place. Please help at a total loss. It is not the pi that is faulty

Please show your configuration and if possible cgminer.log( try ssh to to pi user:pi password:raspberry)
Cgminer.log is located in/var/www

Gl,

can you please PM me your email address? I can only send 5 msgs per hr and have reached my limit Sad

When the LEDs are blinking all the time, in my experience that means there's a fault with the card. I've seen it happen in two circumstances so far. 1.) Overheated card due to fan failure - shutdown, cool off, replace fan and restart - worked again. 2.) Reflashing the MCU firmware from B1/2 to B3 - I had a few cards where the LED would flash incessantly on the last stage - had to restart the firmware flash procedure from start - cured the problem.

If you've got one of the Batch 3 miners with the glued on individual heatsinks (have a look inside) check that they're all stuck where they should be (onto the ASIC chips). I had a couple of these B3 miners land with heatsinks rattling around inside the miner case. Just unplug and unscrew the 4 screws holding the fan, unscrew the 4 screws holding the cards in place and gently slide the hashcards out.

Try starting the miner with all 4 cards, then power off and pull the SD card and open both StartCgminer.log and cgminer.log in /var/www.
You're looking for 4 sets of the hashcard initialisation log below as well as this summary line:

[2017-03-05 20:20:06] A2 boards=4, active cores=7998, speed=763.97M
Ignore the reference to A2, Inno didn't update this chunk of code for the A4.

This is the log for 1 card so you should see 4 sets of this. If you don't see 99 or 100 cores per chip you've got problems.
pllClkIdx is 7 7
