Ultra Under-overclock image for A2 Innosilicon by Emdje - V5.0

[RCMco]

Hello,

I have a problem with a A2 Terminator that I can't seem to figure out. I scanned all 26 pages here and it doesn't seem that anyone else has had anything close.

When the unit powers up it appears to hash normally according to the software stats. However, after about 30 seconds the rate starts to drop (each board) and after about 2 minutes all end up at zero.

I have tested most of the hardware/software and can rule out the following:

PSU - New, replacement is a 1300 Gold
Pi - Tested in another machine and works fine
Cables/Cat5e connection - All work fine
Software - Original software that worked before this problem started. Also works in other machines

Can anyone point me in a possible direction?  I am at a loss.

Thanks,
Anthony

Anthony,
Symptoms say power. Disconnect half the boards from the power supply, and try again.
My slightly overvolted and overclocked (1320MHz) 110 A2 Mega draws 1400ish from the wall, with 3 blades per power supply (gold).

Hi, I have an old A2Mini 24Mhs, first/second release - minereu, what is the correct firmware to install?

Thanks in advance W_M

If it is not under/overclocked pick version 3

What receiver do you use, and which image?

[emdje]

The A2 image was never made to use WiFi out of the box, I think you still need to install some packages to get that going, but I am not sure anymore it is a long time ago since I got the WiFi to work on mine.

Anyone have orginal image file for A2 miner? Thanx!

 Fans working correctly?
 It sounds like you might have an airflow issue and are overheating.

Does any1 have a working image for a Raspberry Pi 3 Model B?

My Psu Went bust and with it the Raspberry pi model A. Since there is no old ones selling atm i just bought a Pi 3 model B and to my supprise it didnt work at all. Dont know whats wrong tbh, I hook up the newly bought 40 to 26 gipo cable to the new Pi 3 and use the Emdje v 3.1 v 5.0 and original. And nothing happens. try to scan the network and cant find any ip belonging to the A2 or Raspberry. Please help if you have an solution to my problem.

[emdje]

I don't have a solution for you 
Maybe Anx has a solution, he has a slightly different version of the software: hhtp://bitcointalk.org/index.php?topic=1141802.0

Good day

I have LKETC A2 Miner with 4 board (60Mh). My SD card is broken, and i do not have copy of it (my mistake). Trying to install your firmware - web working, i can change settings, but miner not start mining. Do your firmware is suitable for my miner? If so - where can i change number of boards?

Found some log's

What wrong with servers? I miss something?
Network same as on my pc and connected thru a router, no firewalls and blocked ports.

Have you tried a different pool address?

[ssharov]

Have you tried a different pool address?

Sorry, didn't do that on first try. Tried today - worked with other pool.
Can you tell - what it can be? I mine on them earlier this year with this miner and all be fine. Pool is working and accessible.

[emdje]

I have no clue to why it suddenly does not work anymore  . Great that it works on a different pool though

Found reason - worker login. Need to use prefix on that pool and i forgot about that)

Minig working fine but after some work time web interface become unaccesible. And no temperature information on real time monitor page (Emdje - Under and Ultra-Overclock version 5.0).
