Cairnsmore1 - Quad XC6SLX150 Board

[chrisp]

How many bitstreams are currently in development?

- Glasswalker is re-writing the Icarus-bitstream, main problem is JTAG noise and meeting the timing?!
- Which bitstream is makomk working on? According to the filename, also some kind of Icarus-rewrite?
- Is EP still working on a (from-scratch) bitstream or are they now waiting for Glasswalker to finish his work?
- Is anyone working on making the TML-bitstream fully compatible with CM1?

I'm working on adding native support to the TML-bitstream with the included FTDI chip.  I've had to rewrite the jtag interface so it's been some time, but i'm progressing nicely.

How does that work exactly chrisp, can you still use a miner like cgminer, or do you need a miner provided by Et? I have yet to even look at making anything work with the Et bitstream.

I am using the ET miner.  Using cgminer would require porting over his interface to the encryption servers and the like, doable, but more work.  So it's the same java app that's distributed on his website.

Looks like I can report succes on makomk's 160 bitstream, with cgminer 2.61 in windows 7 64-bit.

makomk 160.bit on board #62-0008 gives a U: of 0.5 - 0.8 after an hour of hashing using cgminer 2.4.3 on linux.

I'm trying now to flash the 140 MH/s one to see if it is better.

You have the wrong one, the one you want (trust me) is:
shortfin_icarus_cm1_test_160.bit

How do I actually flash the shortfin_* bitstreams?
Using the VirtualBox and "xc3sprog -c cm1 -p 0 shortfin_*.bit" gives me

flash it like the twin_test.bit.

without flashing to SPI:

Code:

xc3sprog -c cm1 -p0 shortfin_icarus_cm1_test_160.bit

With flashing to SPI:

Code:

xc3sprog -c cm1 -p0 -Ixc6lx150.bit shortfin_icarus_cm1_test_160.bit

Make sure when flashing:
SW1 #3 off
SW6 #1 off

SW2 all on
SW5 all on
SW3 #2 off
SW4 #2 off

When mining:
SW1 #3 on
Others same as approve

Did you copy the files to the VBOX? do an ls *.bit and make sure your files are there.The command should be xc3sprog -c cm1 -p0 shortfin_icarus_cm1_test_160.bit no space between -p0. Then you would just change -p0 to -p1, p2, and p3, as each one completes to do all 4 fpga's.

Isokivi,

sorry, I was not clear enough shorting the bitstream name from  shortfin_icarus_cm1_test_160.bit to 160.bit, but I'm using the correct one

Anyway, with the 140.bit I always fail cgminer test, even after a few complete power-off/on of the board, so I think I'm gonna flash the old twin_test.bit for now.

That's what I'm doing... ("-p 0" or "-p0" makes no difference)
But it's not working

I almost wonder if your file was corrupted somehow, you might try downloading, unzipping, and copying it one more time just to be sure something isn't wrong with the .bit file.

Yeah, there probably shouldn't be any reason to use the older non-shortfin variants anymore. The newer ones are 99.9% the same except with improved reliability.

Wait, does that mean your board serial number is 8? If so, don't bother - apparently my bitstreams don't work on boards 1-50.

Edit: though saying that, even the fastest of these shouldn't overclock your board any more than trying to run a standard Icarus bitstream on them would. I'm not sure whether that's reassuring or worrying. Never mind, confused with something else.

Is the error I'm experiencing caused by the fact that my board has SN 26?
Which Controller-bitstream is required? 1.2 or 1.3?

You would need 1.3 for makomk bitstreams.

OC'd to what? the numbers in the filename are todays date right....or are they?

Sorry, should've said. 170 MHz, 180 MHz and 190 Mhz. According to the Xilinx timing analyzer the maximum clock rate for this bitstream is 166 MHz.

Ah, OK, I was not aware of this fact.

Thanks.

You would need 1.3 for makomk bitstreams.

Controller 1.3 also gives me the "ignoring unknown field" errror...

Working after re-downloading the bitstream package... :/
Is any other version of cgminer than cgminer_twintest.exe working?

I'm using 2.6.0 compiled from git in Linux, it looks like there is one made for windows here http://ck.kolivas.org/apps/cgminer/cgminer-2.6.1-win32.zip, no clue if it works on the cm1 in windows, works great in Linux.

My results:
190oc is working on 8 boards without problems!
2 boards need on the 0/1 pair the 180oc one.

Happy hashing everyone! =D

Thanks makomk and congratulations, you have qualify for the bounty!
