I've got an R4 which will not mine, the system boots and it seems that when the auto frequency script runs it hits an error and can't proceed.

Kernel log-

Miner fix freq ...
Fatal Error: DownOneChipFreqOneStep Chain[-1] has Wrong chip index=7893959

Here's the code-

if(max_freq_chipIndex<0)
   {
      sprintf(logstr,"Fatal Error: DownOneChipFreqOneStep Chain[%d] has Wrong chip index=%d\n",max_freq_chipIndex);
      writeInitLogFile(logstr);
      while(1)sleep(1);




Any ideas?

I've rebooted and power cycled a number of times, re-flashed the firmware - tested with another know good PSU. I've logged a ticket with Bitmain but thought perhaps someone on here had seem this issue before and may have a fix. I thought it would be unlikely for both hash boards to be faulty.


***edit - I think https://bitcointalk.org/index.php?topic=1741088.0 is the same problem.

My testing has concluded I have a dead hash board - miner is now functional with just a single board connected.

Hey - I'd been lurking for a couple of weeks and finally decided yesterday to register. So as I understand it I need a least 5 posts and 4 hours on the site - well this will be my 6 post, first thread and I've been logged in for 4 hours 3 minutes........ however I still can't interact with any other areas other than this newbies section.

Have I missed something, I'd assume it was an auto promotion once criteria is meet.

Thanks.

Just registered and thought I'd say hi...... HI!
