I was very happy to learn about the TP-Link 703n, because it was a self contained Linux box with a MIPS cpu and networking hardware built in.  Occasionally I get excited about some other hardware that I have software tools for.

I know the raspberry pi has some nice video interfacing, and is pretty inexpensive.  However, I wonder what the particular reason is that people want to run cgminer from it?

I can only speak for myself.
I like that it is compact and low power.
I'm not having to keep a computer running just to service the ASICs.

I've also noticed my Little Single is running more consistently.
On the Windows notebook, the ASIC fan slowing down periodically would get my attention
and the screen would show error messages until something finally got worked out and it would get back up to speed.
I'm suspecting this was a Windows issue.  I didn't run the ASICs on Linux other than the Pi.

When attempting to mine scrypt with the latest version of CGminer I get this error  "error -56 enquequeing: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel)".   The miner then procedes to disable the GPU.

I'm running a XFX 5870 HD 1GB VC on Windows XP SP3 with 2GB system ram.  the card is recognized as GPU 0 and the -n function shows it as ATI stream.  It's set to run on Give-Me-Coins pool in this fashion   

"cgminer --scrypt -o http://ltc.give-me-coins.com:3334 -u USER.WORKER -p PASSWORD"      via the BAT file

  In between tries I delete the bin file as well as rename the conf file which I also rename as to not interfere with the BAT file.  This error also occurs when I try and run CGminer.exe through the conf file.  Running from the cmd prompt also has the same results.   I'll also add that I have no problems mining BTC with card and CGminer.  CGminer was not compiled.  I downloaded the binaries  from the main repository.  Any suggestion to solve this problem will be appreciated.

    did you have?

    setx GPU_MAX_ALLOC_PERCENT 100
    setx GPU_USE_SYNC_OBJECTS 1

    in your batch file or before calling cgminer?


Funny thing about this is that I have always included this in the BAT file.  Initially the miner was just instantly shutting down no matter what I did.  I then got some help from the MOD at my mining pool and he did some research and found out that Windows XP does not natively support the SETX command.  A little bit of info that all the guides LEAVE OUT!  I had to download Windows XP Service Pack 2 Support Tools to get the SETX function into XP which was a whole nightmare in itself (but I won't go there).  Once I got that setup incorporated the setx GPU_MAX_ALLOC_PERCENT 100 into the BAT file but not the setx GPU_USE_SYNC_OBJECTS 1.  There seems to be a lot of confusion about how to run CGminer on Windows Xp as opposed to Windows 7 or Linux systems.  If you could explain what the setx commands do it would be much appreciated!

Thank you guys, this is working just fine.

I'm working on it for BF1 devices (red and blue are the same) since I received one. Should be in next version.

Why do I get "Pool 0 not providing work fast enough".  I get this when I'm solo mining.  I'm solving block and so it seems like it's working, but when I get this message the block I solve per week is lower that expected (by more that 10%).  Is this a problem, that I can debug?

Because of vardiff, the UI now shows "Accepted Difficulty" instead of simple count of accepted shares (because not all shares are equal in a vardiff world).  So if you find a share with difficulty 16, "A" will increase by 16 and not by 1.

I just looked up a 5870 and see it's a single GPU like a 5970. Here's the conf I run on my 5970 miners:
{
"scrypt" : true,
"gpu-reorder" : true,
"intensity" : "18",
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "8192",
"gpu-engine" : "725",
"gpu-memclock" : "1000",
"gpu-vddc" : "0",
"temp-cutoff" : "95",
"temp-overheat" : "88",
"temp-target" : "75",
"temp-hysteresis" : "9",
"gpu-fan" : "0-85",
"auto-fan" : true,
"gpu-threads" : "1",
"log" : "5",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}
How much RAM do you have installed? I can run 4x5970s on 4GB RAM with a Sempron 140.

i.e. you didn't use the correct drivers for cgminer.
