on mini image i could start cgminer thru putty and file with command.
but 4.0 version isnt working.
when starting file nothing happens.
and i cant copy paste command to putty as it starts cgminer in middle of pasting. anyway to start miner using ssh?

Cgminer starts automatically, no need to start is manually. Just put in the right info in the webinterface.
If you do want to start it manually you need to disable auto startup.
The problem I encountered with starting trough putty is that once you disconnect, cgminer stops.

EDIT: I now read you say 'mini image'. Problem with that image is that I can't check what happens with that one. I have no new A2 boards to check my work, that is why it says experimental.




About the sha256 reference in your picture. That is just a reminiscence in the code from when it was first used for the A1. I fixed most references in the output, but missed this one. Will fix that in the next release (which will take a while, have been busy with submitting paper for review).

cool thx for reply.
mini image was great for my mini a2 terminator 29mh/s
what i used to do was to install screen then bash it and start miner manually. was great and I could see all errors and hashrate.
with full version I cant do it properly. I mean I can start cgminer but I dont have stats in cgminer (no hashrate. no errors etc) very weird. any idea why? its like bottom of cgminer is there but top not.

Can the download for the new A2 mini also be used for the new A2 110 Mhs?
And many thanks for the good work!

I have a similar issue with both my A2 110mh, if I change the settings, cgminer starts and then stops a couple seconds later, and basically won't start again.  If I power cycle the machine, then it seems to hash again with the correct settings.

Also, how can you reboot the machine remotely, and what's the superuser password?  I tried via ssh, but the default pi/innosilicon which logs you in doesn't grand SU.

I am having the same problem of not getting the Text User Interface when running cgminer manually. It just scrolls everything from bottom to top without being able to issue any keyboard commands. Have seen this before when compiling cgminer without libncurses5-dev (required for the text user interface).

I'm using the complete image of version 4.0 from here: https://mega.co.nz/#!zME2Va7b!lT3Gu6F0CL3i5ll0yl3SS2pn78NVpgZcJVITEnAyW9E

Also, it would be nice to have --failover-only and --no-submit-stale as options from the web UI...although it is easy enough to modify index.php
P2Pools work better with --failover-only and submitting stale.


P.S. Thank you emdje for all you have done. I just got a couple A2 Terminators (one older one that works with your image and a newer A2 Mega) and this thread has been helpful.

Thnx for the praise .

I haven't gotten around at working on the A2 image lately, and unfortunately the image on the machine I was using to build the software has failed on me. The latest modified source is on there, and need to get it off and on another image first before I can continue.
When I have time I will look make sure that the libncurses5-dev is installed before I build cgminer. Thnx for that tip.

Most probably not. The image posted on the first page for the A2 Mini Terminator is not tested well, you might try it on one of your machines it is safe to try, but I don't think it will work great.

I received a broken A2 8 chip blade to fix my own broken one and I wasn't successful, but mine was pretty burned and I think more things are broken than just the chip.

Do you know what is broken on the blade? How many chips, components ect? If you could post photo's that would be awsome.

Which PCB version?
I found that PCB version 20140625 (aprox 2cm longer) has about 10% better efficiency on the same frequency in comparision with PCB V3 or V4.
