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

[BakSAj]

Im glad you were finally able to compile it, good job! Please release new cgminer separatelly from A2 image, so we dont have to flash the whole thing.

[emdje]

What do you get for output when you append to the newly compiled cgminer binary:

 --version|-V        Display version and exit

Also it looks like its only displaying 2 blades?

I will take a look at you first question/suggestion tomorrow, it is very late here.
But to answer you first. I have an A2 Mini  , so only two blades.

Something broke on my pi where the miner is running on To much fiddling I guess 

This is what I get on the Pi I compiled cgminer on:

Code:

pi@raspberrypi ~/Downloads/cgminer-4.7.0-A2-Working-dont-change $ sudo cgminer --version
cgminer 4.7.0

So that is good

It is not done yet, cgminer 4.7.0 does not start automatically yet.
When I don't have to change anything else on the image in startup scripts I can release it on its own.
In previous cases a newly installed miner would mine a couple of minutes for me, which donations for my work.
When I release it on it's own I do expect some donations

When I do this in the pi where the miner runs on i get this   

Code:

pi@raspberrypi /var/www $ sudo cgminer --version
cgminer 3.9.0

Going to recopy the file to make shure it is the same

[emdje]

Copied version 4.7.0 on a usb stick. Checked it on the usb stick with the --version command, it gave back version 4.7.0
Checking the same file on the same usb stick on the other pi it gives version 3.9.0 again 
Putting it back in the other pi and checking that file with the command it gives version 4.7.0 again

very weird

hmmm....

[Prelude]

Good stuff! Definitely going to send you a couple beers when you release it.

Emdje how do i see cgminer via putty ?

Emdje how do i see cgminer via putty ?

For Ssh only, using putty follow this:  https://learn.adafruit.com/adafruits-raspberry-pi-lesson-6-using-ssh/ssh-under-windows

Or better: http://www.youtube.com/watch?v=ZkvHHkWmKSY

Hope this helps.

try:

echo $PATH

and check in /usr/local/bin

There is another copy of cgminer, most likely the ./cgminer -V is pulling from the $PATH variable

Yes that worked, it shows now that it is cgminer 4.7.0, however it only runs from the command line and shows only invalid nounces unfortunatly. Have to look into that

Hi emdje,

Is it possible to view cgminer like that through putty using your 2.0 firmware? Or is it only made possible with your newer unreleased firmware?

Hi emdje,

No when it is already running, but if you stop cgminer through the webinterface you can.
Start up putty, log in, navigate to the /var/www folder (cd /var/www) and type the following (with your own pool info of course):

Code:

sudo ./cgminer -o stratum+tcp://eu-01.miningrigrentals.com:3333 -u emdje.3166 -p x --A1Pll1 1300 --A1Pll2 1300 --A1Pll3 1300 --A1Pll4 1300 --A1Pll5 1300 --A1Pll6 1300 --diff 4096 --api-listen --api-network --cs 8 --stmcu 0 --hwreset --no-submit-stale --lowmem

When you receive an error and cgminer is not starting type the following:

Code:

chmod +x cgminer

.
This will mark cgminer as an executable. Then try to start it again.


I only use it to test various builds of cgminer. Somehow the autostart does not work properly.

[Prelude]

Cool, thanks for the info. I'll try it later.

Any luck getting 4.7.0 to work properly?

It runs when started in the terminal, but not throught the webinterface. And the output looks funny. More work is needed (and more spare time is needed ).

Hi, i have bought a A2 Mini first release, what images i have do download to restore on the sd card? Which release of cgminer is installed in the iso? Is possible to set 1000Mhz freq. in this release of the firmware to save power consumation?

Thanks in advance W_M

Version 2.0, containing CGminer 2.9.0 can be set to 1000 MHz, and yes that saves power (haven't written down how great the difference was, can't remember)

You need 7zip to unzip the image and image writer to 'burn' it to the sd disk.

The ip adress is the link to the web interface (mine is http://192.168.178.21), I found mine by logging into the router and looking for connected devices.
On the web interface you can set you pool information.

[wolf_miner]

Thanks emdje, is possible to change the ip address to 192.168.1.xxx ?

[fhh]

Thanks emdje, is possible to change the ip address to 192.168.1.xxx ?

not necessary emdjes  image is graping an address via DHCP

Guys I currently run 9 zuesminers Thunders, but looking at the A2's as an alternative as they appear to consume less power. The images your posting will they function on all late model A2's including the 30Mhs 28nm unit? If so what results are you getting? It looks like factory speed is 30 Mhs? what is the highest stable speed from this unit? Power consumption? Looks like factory power supply is 430w. How much power will the 30MHs unit consume when overlocked?

Thanks in advance
