CGminer v3.8.5 on Broadcom based DD-WRT / OpenWRT

[nelisky]

Any updates on Ztex support?

I can compile a version with it in, but I don't know that anyone has got it working. Look back through this thread and see if you can get any info from those who have attempted it.

And thanks Ned

I'm using ztex in OpenWRT, in fact I did much of the development with that as target (as it is the hardest to debug, might as well make it work there to start with). Can't speak of DD-WRT.

Does it work great, without stales etc. I heard something about offloading problems on Ztex Boards?

[nelisky]

It works just fine in my experience. I have the router dedicated to cgminer, mining to p2pool and it has no difference that I can perceive from the same setup with a full linux desktop.

[BR0KK]

Oh thats nice since i want to get rid of my mac mini, what router do u use ?

[nelisky]

TP-Link MR3220 (also tried the MR3420 which is basically the same thing only with better wifi range, so I'm using that one as originally designed )

[BR0KK]

thanks

try to get one from ebay now....

is it hard for a non linux noob like me to get cg miner running on that hardware (i know how to do the openwork DDwrt part )

Well, I grabbed openwrt sources and compiled it with the needed kernel modules (so I didn't have to load them afterwards which could fail due to lack of space). I then cross compiled cgminer and presto.

Ok, I skipped the step of getting ztex worker going on the cross compiled environment, but that has already been done and does not need to be done again.

hi,

and what is with the ztex bitstream? My tp-link 703n says there is not enough space for it? Or can you give me your compiled cgminer and it do not need it?

have u seen this?

http://en.qi-hardware.com/wiki/Icarus#Using_TP-LINK_TL-WR703N_as_host

it uses cgminer 2.4.1 though, and theres a bug, right now you cant use privileged API.

[Chefnet]

yes I have, but I don't get my ztex working (libusb 1.0.18 is installed so I think the bitstream is missing)

Well, you should be able to fit the one bitstream you are actually using without problems, but if you want the full bitstream directory or you have multiple ztex boards with different versions running at the same time, you'll need to set up usb storage. That is what I do.

[Chefnet]

do you have a small tutorial for both usb storage and using it with cgminer and ztex?

[nelisky]

No, I don't. I'm using my own build of OpenWRT so my steps are not directly useful if you are using anything else. Still, I can help anyone who is willing to write said tutorial, and get that into the cgminer distribution readmes.

All in all it should be very trivial to get that up and going once the correct libs and modules are in place. For usb storage I'm using a usb key with 2 partitions, one with ext4 and one with swap (just because, not really needed). Look at http://wiki.openwrt.org/doc/howto/usb.storage for guidelines and ask if you have any doubts.

As for cgminer, you'll need both the cgminer binary and the bitstreams directory, both living side by side in the same directory.

[Chefnet]

thank you.
I will give it a try but I'm so busy it will take a while.

can I place only the bitstream folder on the usb device or must it be the whole cgminer with the bitstream?

You can place only the bitstream folder but you'll have to run cgminer with the current directory being the parent of bitstreams.

Once you do give it a try let me know if you have any issues. I might try it out with a plain vanilla OpenWRT one of these days too, but can't really promise I'll beat you to it.

[BR0KK]

Bought a mr3420 will try it as soon as I'm home.

When you guys sort out how to get the ztex working in vanilla OpenWRT/DD-WRT, post the guide here and I'll include in the readme

Openwrt is Running now i Need to find Out how the Rest will work
€:

i have USB Working on that thing. Now need to do the part with storage access and later the part with ztex drivers

hmm I'm running into the mentioned space constrains (only 28KB left ....).... could anybody tell me how to make a low memory version of open wrt?  Or what of the installed software i do not need ....

[P_Shep]

Updated for cgminer 2.4.3:
https://github.com/downloads/pshep/cgminer/cgminer-2.4.3-mipsel.tar.gz

Now including Ztex & ModMiner Quad
(though I don't know if they work)

[Garr255]

I'm going to try loading this on a MR3020, although I won't have anything to test it with until Monday.
