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

[GoldZuGeld]

ok thanks for this explanation.

now i have another problem:
serialmodules is started but there is no folder tts in /dev/usb

there are 2 usb sticks connected over a hub

[P_Shep]

If you are ztex (which I assume from needing the libusb) you won't even need to run serialmodule; it doesn't use a serial port.

I don't have ztex so I can't tell you how to get it working.

[GoldZuGeld]

ok, my ztex quad isn't running after following your readme.
is it possible to check that the ztex board is recognized by dd-wrt?

[P_Shep]

I really don't know much about the ztex.
As far as I know it just needs libusb v1.0, which I downloaded and compiled for dd-wrt.

As I said in the readme and OP, you're on your own...
I can't think of a reason why it shouldn't work, but I don't know how to do it.

Maybe you could get support form the ztex thread?

[BR0KK]

it should list when you try out "lsusb".

mine did but i desperately need a low mem version of openwrt or ddwrt for a tplink mr3420

[GoldZuGeld]

lsusb shows this

221a:0100 is the ztex device, so cgminer/libusb is not detecting it.

What log output does cgminer give?

should get something like this:

 [2012-07-02 23:39:57] Not a ZTEX device 8564:1000
 [2012-07-02 23:39:57] Not a ZTEX device 0409:005a
 [2012-07-02 23:39:57] Not a ZTEX device 0409:005a

 [2012-07-02 23:39:57] Not a ZTEX device 0000:0000
 

but if you get
 [2012-07-02 23:39:57] Not a ZTEX device 221a:0100

then something weird is going on.

maybe it's a bit late for me but i have only do this:
tail -f /opt/var/log/YYYYMMDD-HHMMSS.<PID>.log

replacing YYYYMMDD-HHMMSS and whats with the PID?

[P_Shep]

PID is process ID

just look in /opt/var/log directory for the lastest log file.

ok, not bad, i thnk...

ok something wrong in my credentials for the first pool. but second pool does'nt work, too.

Looks like there's something wrong with the bitstream. You copied it over? It's in the right place? Is it readable (chmod +r)
I think it should be in /opt/bin/bitstreams, but maybe it should be somewhere else.

[GoldZuGeld]

whoops. Linux newbie fail  

seems that i've renamed the bitstream file to bitstreams instead to copy it into a bitstreams folder.

I think this is a mistake or something is missing in your readme:

Copy the bitstreams to      /opt/bin/bitstreams

you have to create the bitstreams folder first an then there is a / after bitstreams missing, i think.

EDIT: OMG! It works! Thank you so much! In the next few days, I try to add some information for ztex boards for your readme.

Excellent, well done!
You're the first known ztex on dd-wrt

So I'll add an instruction to mkdir first

(but yes, the intention was top copy the files to the directory )

Wow, impressive, I really like this set-up for mining

[GoldZuGeld]

seems to work nicely.
E3200 + Usb Hub + Ztex Quad + Coolermaster GX 450
runs perfect

but hash rate is a bit lower than on my pc. only ~ 740mh/s instead of nearly 900.
Any Ideas?

[BR0KK]

it takes time to go up to full speed

I have the same problem with the Rpi.

How stable is the setup?

it runs the whole day today, without problems but as i said hash rate a bit lower than on my desktop pc.
I have to build a case for the configuration, then it could run 24/7. Until that it only runs ~12 hours a day.


I'm using a noname usb stick with 1GB storage. are there many reading operations to the stick?
Or maybe the usb hub sucks, because it's a cheap hub.

[BR0KK]

why? i run my setup 24/7 for 7 month now; Without casing Nothing happened so far

[GoldZuGeld]

just need to find a good place, where the noise is not annoying
