Hi,

I'm hoping someone can help me get BFGminer working with scrypt.

I've gone through all the documentation, all the posts I can find on here and other places on the web about getting scrypt running in BFGminer, but I still can't quite get it to work.

Using version 3.1.1 (which has scrypt compiled into it), I can connect to a pool, and send of a get work request, but then things seem to fall apart.  

I'm running an MSI 7970 card and I'm launching BFGminer with the following batch commands:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
bfgminer --scrypt -o pooledbits.com:8337 -u BLANKED.1 -p x -I 13 --shaders 2048 --debug 2>log.txt


The following is what gets dumped with debugging turned on:

At this point, BFGminer simply closes down.

Can anyone give me any advice/help/suggestions about what is happening and how to get it to work.

Thank you very much in advance.

I'm trying to get it to work too, and I generated a debug log file that looks very similar to yours.

I notice you have OpenCL 1.2, and I have OpenCL 1.1

I'll come back here to post my findings after I try to update my software.  Might take me a couple of days, I am trying to run non-stop right now with bitcoin mining, and I don't want to restart for things to take effect.

Edit:  I forgot to mention that I'm running WinXP SP3 and it did not originally have setx, so I had to download a copy of it, but I have correctly implemented it in my batch file before the bfgminer command+arguments... I just don't know if it's part of my problem yet or not.
