Well have CM1 up and running on SHA256. So I know it's working.
So I'm ready for when ever kramble has something he wants tested (I think I can figure out SW1 and SW6 setting for a bitstream update. but take your time I'm in no rush at all.

I'm very close. I've got a working bitstream and driver for cgminer 3.1.1 however both are currently very buggy. The bitstream is only hashing at about a quarter of the expected rate, but I think I fixed that in the overnight build which I'll be testing later today/tomorrow (Saturday is family day in the kramble household, so not much development will get done today). Seems I was caught out by clock domain crossing again (novice error, I thought I could use the hasvoodo top as-is, but the timing is slightly different on the golden_ticket strobe in the bitcoin and blakecoin cores). Cgminer is a more serious problem as it crashes in the curses module on windows, so needs to be run with the -T flag, strangely it works OK with ztex though. I'm seriously considering abandoning cgminer in favour of bfgminer, though the change to the mingw build environment is putting me off at the moment.

the board I sent kramble has the hashvoodoo project on the controller and the fpga's you might want to play with that Wink
https://github.com/pmumby/hashvoodoo-fpga-bitcoin-miner

are you using the xilinx usb programmer and loading the bitstream via the jtag ports?

As bluedragon suggested I'm currently using the hashvoodo firmware as this was already installed and I didn't want to take the risk of reflashing it at this early stage (hashvoodo also has better clock distribution as it uses LVDS). I'm currently using the onboard programmer via VirtualBox/xc3prog which to be honest is a right dog's breakfast. It is just so temperamental as to be almost unusable, but I'm persevering as this is how its going to be programmed by the end users. I can usually manage to get the bitstreams loaded up OK after a bit of a fight, but I've never once had a confirmed verification that the load succeeded. I'm also getting drop-outs of the USB driver while mining which require a complete power cycle to reset which is very frustrating due to the need to reload the bitstreams (I'm not yet at the stage where I want to reflash the configuration ROMs).

EDIT Embarrassed Having finally taken the time to RTFM I now understand why I was having such problems. The -I switch is only used to load the bitstream used to flash the MCS ROMs, but I was using it for the main bitstream. It works much more reliably without it  Embarrassed

Anyway hopefully I'll have something for you to test in the next couple of days, though the clock speed is lower than I'd like to see (only getting 100MHz ATM, compared with 200MHz for the ztex). I'll also look to getting a port for the official 1.5 firmware based on makomk's code (it needs more than just swapping the clock source, as this version retains the icarus chaining of the fpgas, so only two serial ports rather then the four for hashvoodo), though as I'll have to flash the firmware I want to get the hashvoodo mostly complete before risking this.

As I said no rush. A family day is very good idea. Smiley

I am very much a noon on this  and fumbling in Linux adds to the fun. Do not have the xilinx tools installed yet jI am running it on bfgminer right now but have the virtual box.

That sounds like my next step then hashvoodo.  Should I install 14.1 or 14.2? What to be on the same version just in case the is a subtle difference that could bite us.

 I am running it on bfgminer ATM but have Blake version and current cgminer available.

Enterpoint Cainmore CM1 port https://github.com/kramble/FPGA-Blakecoin-Miner/tree/master/experimental/CM1

This code is derived from the HashVoodoo FPGA Bitcoin Miner Project
https://github.com/pmumby/hashvoodoo-fpga-bitcoin-miner

Licensed under GPL. My thanks to Paul Mumby (Glasswalker), makomk and TheSeven.

Test bitstream https://www.dropbox.com/s/m901icq7pt9nl4l/CM1-hv-v04a-80MHz-ucf-75-fmax-78.bit
Faster version https://www.dropbox.com/s/xm8gjm7b2qnhgig/CM1-hv-v04a-120MHz-ucf-100-fmax-103.bit
Faster version https://www.dropbox.com/s/ledl95oolt7lgts/CM1-hv-v04a-150MHz-ucf-130-fmax-140.bit
Faster version https://www.dropbox.com/s/bbevqb8792emll9/CM1-hv-v04a-175MHz-ucf-150-fmax-161.bit

NB This requires the hashvoodo firmware from https://github.com/pmumby/hashvoodoo-fpga-bitcoin-miner/downloads
Use hashvoodoo_controller_25.bit from any of the later releases, NOT the 08_04_2012.

Some useful instructions at https://en.bitcoin.it/wiki/CM1Quickstart (these are for bitcoin but the programming guide is relevant). It was rather temperamental and may require multiple attempts at programming to get the bitstreams to load. I would recommend just loading the bitstream and not attempting to flash the configuration ROMs.

What I find to work is the following [EDIT Embarrassed After RTFM I took out the -I switch which was causing most of my problems, it works a lot better now] ...
Boot the VirtualBox machine and copy the bitstream (I use "nc" rather than fiddling with usb sticks, ftp also works but needs passive mode).
Power up the CM1 board wait for it to fully load
Set switch 3 OFF (configuration mode) then connect the USB cable.
Execute "xc3sprog -c cm1 -v -p0 CM1-hv-v04a-80MHz-ucf-75-fmax-78.bit" for each fpga in turn p0, p1, p2, p3
This takes about 20 seconds, successful loading is indicated by bright red and yellow LEDs, with a short flash of green.
Return switch 3 to "on", the red LEDs will now flash slowly.
Shutdown VirtualBox (run "init 0"), disconnect then reconnect the USB cable, then start cgminer. I have supplied two windows versions and also on github (uses updated driver_icarus.c).

https://www.dropbox.com/s/m18kr3kgrl102w2/cgminer-311-2013-11-16-CM1.exe

https://www.dropbox.com/s/d3gbhpqboo9itei/cgminer-311-2013-11-16-CM1-notest.exe

The second one is a fallback if the fpgas are not detected as valid icarus devices (the icarus detect result is ignored).

NOTE, these are rather buggy (the -T switch is required else it crashes in libcurses). Run them as follows on windows (using the relevant COM ports for your system) ...

cgminer -T --disable-gpu --icarus-timing long -S \\.\COM20 -S \\.\COM21 -S \\.\COM22 -S \\.\COM23 --url localhost:8772 --userpass username:password 2>log.txt

I've swapped the green and blue LED designations, green is now the I/O indicator and blue is a valid hash (it made more sense as blue is much brighter).

Its all very rough and the current speed is very slow (80MHz) but this will improve in future builds. Dynamic clock is enabled in the bitstream but not supported by this version of of cgminer.

Good Luck!

[Edited for typos etc, I was a bit rushed yesterday]

I will put stratum-mining-blakecoin code on Github this weekend but it is highly experimental and not fully functional also it imports stratum which might also have bugs that have not been found yet!

the merkleroot calculation is not done in one place in the stratum pool software but try this:

Code:
class MerkleTree:
    def __init__(self, data, detailed=False):
        self.data = data
        self.recalculate(detailed)
        self._hash_steps = None
    
    def recalculate(self, detailed=False):
        L = self.data
        steps = []
        if detailed:
            detail = []
            PreL = []
            StartL = 0
        else:
            detail = None
            PreL = [None]
            StartL = 2
        Ll = len(L)
        if detailed or Ll > 1:
            while True:
                if detailed:
                    detail += L
                if Ll == 1:
                    break
                steps.append(L[1])
                if Ll % 2:
                    L += [L[-1]]
                L = PreL + [doublesha(L[i] + L[i + 1]) for i in range(StartL, Ll, 2)]
                Ll = len(L)
        self._steps = steps
        self.detail = detail
    
    def hash_steps(self):
        if self._hash_steps == None:
            self._hash_steps = doublesha(''.join(self._steps))
        return self._hash_steps
        
    def withFirst(self, f):
        steps = self._steps
        for s in steps:
            f = BLAKE(256).digest(f + s)
        return f
    
    def merkleRoot(self):
        return self.withFirst(self.data[0])

this should be Blake-256(SHA-256(SHA-256(merkleRoot))) as it is in the wallet code?

Excuse my ignorance but I am still trying to figure out what is wrong (above code still gives merkleroot mismatch in client). I started to analyze cpu miner code and found following:

Code:
static void stratum_gen_work(struct stratum_ctx *sctx, struct work *work)
{
unsigned char merkle_root[64];
int i;

pthread_mutex_lock(&sctx->work_lock);

strcpy(work->job_id, sctx->job.job_id);
work->xnonce2_len = sctx->xnonce2_size;
memcpy(work->xnonce2, sctx->job.xnonce2, sctx->xnonce2_size);

/* Generate merkle root */
sha256d(merkle_root, sctx->job.coinbase, sctx->job.coinbase_size);
for (i = 0; i < sctx->job.merkle_count; i++) {
memcpy(merkle_root + 32, sctx->job.merkle[i], 32);
sha256d(merkle_root, merkle_root, 64);
}

and I dont see here using blake algo to generate merkleroot - maybe here is the problem?

Hi,

I just compiled the blakecoind under Mac OSX 10.8.5 and testing it for Solo Mining.
Time to retire my big & loud Win8 GPU system. A Ztex 1.15y attached to a r-pi is doing the mining.

If anyone is interested, I could compile a binary of the blakecoind with static libraries and upload it to MEGA.

and will not even try to compile to BlakeCoin version.

Will work for BTC and DEM (eMark)   No joke!   Network, WiFi, IPv6

The merkleroot is a double SHA-256 and uses the same ecdsa curve as Bitcoin like I have said in pm to you but the stratum pool software does not just do a single doublesha on the merkleroot  Huh

also the cpu miner uses the getwork2 for mining the wallet?

trepex

not tried to compile for Mac OSX myself and the makefile is almost untouched and should be very similar to Bitcoin 0.8.5

it is best to check how others are building Bitcoin 0.8.5 on Mac OSX and apply the same build method and any tweaks to the makefile to get it working

please report your results here as you are first to try and build on Mac as far as I know Smiley

Hi - correct me if I am wrong but when you mine a wallet you don't calculate merkleroot therefore you can find blocks with cpuminer or cgminer, but when you mine with stratum pool then cpuminer is calculating merkleroot (just sha algo), then stratum server calculates it once again (with blake algo according to your modified function) and then wallet checks merkleroot (also with blake algo) and this check fails. Thats why I pointed this part of stratum work build function in cpuminer as first step which logically is wrong (assuming wallet function as baseline).

yes I see what you mean  Undecided

I have tested with a modified stratum proxy and the block candidate is still rejected but I have not yet tried with a modified block submission method and the modified stratum proxy at the same time this is the only way I can think of to avoid a calculation error like the one you are suggesting

only issue with that fix is the pool has a lot more duplicate shares that get submitted Embarrassed

Yep, sorry its a bit rough at the moment. I wrote some quick notes here https://github.com/kramble/FPGA-Blakecoin-Miner/blob/master/cgminer/cgminer-3.1.1/README.txt

I did dry to get it working on cgminer 3.4.3 (the latest version that included ztex support), but no joy, its broken (works on ztex though) .

I'll make a start on BFGminer tomorrow, cgminer just doesn't seem to support the CM1 (kano didn't get his dev board, so no surprise there, its not easy to code blind without hardware to test on).

Turn switch 3 back on, the red LEDs should start to blink. If you used the VirtualBox instance to program the devices, shut it down (init 0), unplug then replug the USB cable, then start cgminer (runblake.bat).

Switch 2 is the fan override since I'm not using the supplied fans. Switch 5 is the clock speed setting, needs to be in the opposite direction for the hashvoodo firmware.
