Yes, that's right. You first set your desired freq and then let the script find the best voltage setting for each of the four chains in your L3+.

Could you post what you did exactly posting the exact commands you entered?
The "command not found" normally hints that you are missing the path to the command. I.e. if you are in the directory where l3plus_autotune.py is located, you need to add "./" in front of it to tell the shell that you want to execute the command in the same folder.

HTH

Thanks for spotting that, I fixed the typo.

I am a bit unsure where you could be stuck or what could be missing.

Could you change into the bitmain-tools/scripts directory and try the following two commands and paste the output here:


Generally, the more info you post, the easier is it to guide you through the procedure.

Ah, good I asked. You seem to have installed a rather minimal Ubuntu VM with no python, but no problem. Do the following:


While at it you might also want to install the required paramiko module:

But already after your first step the error should look different (reporting that you need paramiko too).

Oh well, another new cgminer output with json glitches, this time it's the L3++.
Don't know why every version of cgminer I have met has invalid json output that has to be fixed first.

Anyway, thanks to your pasted output I could (hopefully) fix that as I have no L3++ to test against.

Please change into your bitmain-tools directory and do:


Let's see if that gets us any further.

./l3plus_autotune.py
no ip no -i ?

Interesting, the json output you posted gets parsed ok here and obviously it complains about an error at char 1309, though the string you posted is only 1308 chars long.

It sounds like the json output from cgminer has some extra whitespace or linefeed but then again the json module should be able to work with that just fine.

I am a bit lost here, could you please pm me or post the complete output of the following command(s):

The above installs the networking swiss army knife 'netcat' and uses netcat to fetch the json output directly from cgminer api port of your miner so that I can see what could failing here when reading it from my script.
