I played a little around an found out, that the nonce does'nt have to change the endian on arm.

Is it normal that a Generated target looks like this:

Generated target 0000000000000000000000000000000000000000000000ffff00020d7800780d

on a working stratum machine, it look like this:

[2012-10-13 00:01:34] Generated target 0000000000000000000000000000000000000000000000000000ffff00000000

No it is not normal. The last 8 hex characters should always be zero. The working stratum example is what a normal diff 1 target should look like.

after the call  swab256(target, rtarget); the last bytes of target are destroyed.

But rtarget looks good.  Huh
Very weird. swab256 is a pretty simple function swapping the 8x4byte array members (which means 8 hex values) of rtarget to target and then byteswapping the values of each 4 byte value. It looks like something is stomping on the last few bytes on your arm build though. The endian issue could be coincidence and not the real problem.
I changed the default size of target and rtarget like this:
Code:
static void set_work_target(struct work *work, int diff)
{
        unsigned char rtarget[36], target[36];
Now i got targets like expected..

But still the same problem that i get rejected on stratum

I still have problems with 2.8.3.
Now i made a logfile : blogya.de/downloadsonlyforyou/logfile.txt
I crosscompile it for ARM7 maybe that is the problem.

is it normal, that in stratum protocol the nonce is different endian, than the nonce that is submitted by the worker ?

--Fix-protocol brings 2.8.2 with my own driver to run. Now it works with external Proxy like expecteded. It works with Diff 16.
When i try with the internal stratum protocol, it only shows diff 1 and never goes up.

Has anybody tested the stratum implementation on an ARM7 ?

Any Ideas. Going now back to 2.7.5.

That's interesting... Think about it.

Must there a change in the driver for the stratum mining ?
with 2.7.5 i am using exactly the same driver with an external stratum pool and this combination works.

With 2.8.1 mining on a none stratum pool works.

You have to change the Device Identifier Code.
Cause My Spartan 6 have: Device IDCODE= 0x4401d093. That is the latest Revision that Xilinx delivers.

the 'tml-leibniz.bit' bit stream file, has the 10x size of a standard bitstream file and it is an 'Ascii' file and not binary like a standard bit file.
It seems that 'tml-leibniz.bit' is an ngc, ncd file or something like this.
