Hey the link on the technobit site and in this thread don't work for me if anyone could send me the 0.2.0 firmware to clelarge@xs4all.nl i will put it online on my server

my technobit tp link keeps hashigng but i can't get the cgminer api log and none of my pools show any hashrate ever since the firdt reboot after i added a hex16b to my 3 hex16a2's, even if i remove the b it keeps doing this

--enable-hexminerc is enough
Made sure you pass to cgminer default-miner as c.you can read change log first

Anyone knows how to set it the tp-link to reboot a few times a day?

0 8,20 * * * reboot

Hi,
I understand everything, but I paid 3 months ago, I no longer have patience!

Uhh guys.

I think I have a defective board

There is also quite a nice hardware mod - but obviously involves opening up your 3020... There is a position on the PCB labelled up as a resistor (R113) - located next to the micro USB power connector... Solder a link across this and your MR3020 will happily take its 5 volts from the normal USB connector (normally 5v output only) - which is great because the Technobit boards happily supply 5v down the USB connection (or from USB hub)... Thus effectively powering the 3020 from the supply feeding your miners whilst cutting out the need to run an extra cable just to power the 3020.

Got mine today, working perfectly, stable 260Ghs on a tl-mr3020 with patched firmware and default settings.
But this thing is incredibly noisy ...

Interesting! Will the technobit OpenWRT image with cgminer also work for ASIC products from other manufacturers like BFL, HF, etc?

Great tutorial Zich,
Congrats for the good work.

have used your perfect HowTo for the TP-Link Router

- the easiest solution

Looked into other router and also configured dhcp server on my linux machine. The MR3020 did not want to connect to anything. Even nmap could not find it.
Alas, as the serial console worked, the problem was obvious. It was configured to use a static ip, but no ip was provided. Hence, I totally bricked it.

This week I bought one MR3020 and flashed it with the technobit firmware (openwrt). Everything worked fine until the switch of the lan interface to dhcp.

The MR3020 started, but no connection was possible. Trying to switch the MR3020 into failsafe mode failed - neither by pressing the WPS button or by change the position of the sidemounted switch. So I bought a CP2102 and followed this guide (no additional resistor was needed).
Afterwards the MR3020 worked again, but this morning the usb psu was defect and I had to use one of my phone usb charges. In the end, I am starting to hate the MR3020.

I found that running on a D-Link DIR-505 to be a bit more stable since it has twice the ram and twice the flash of the MR3020.  It's also half the price (at least when I bought it on sale).  I'm also running over wifi, which Technobit disabled on their firmware image.

I copied over the cgminer binary from an MR3020 and did an opkg install of screen, libcurl, librt and udev and set up some scripts to automatically run cgminer on boot.

Got my board delivered

Can someone tell me, which cgminer version i should use, or is it necessary to use the tplink router whith the hex8a1?

greetz

Damn that's some good instructions!

Thanks again for posting!

Zich,

Do you have the instructions for updating the tplink for use with the hex miner?

Thanks for your great detailed instructions.
