There are few things you need to change for BFSB hardware:
in bitfury-config.h

Code:

#define BITFURY_MAXBANKS 8
#define BITFURY_BANKCHIPS 14

should be

Code:

#define BITFURY_MAXBANKS 4
#define BITFURY_BANKCHIPS 64

as there are 4 banks of 4 boards, each with 16 chips

Then in tm_i2c.c you need to comment out (ore remove) the line

Code:

#define BF_OE_ACTIVE_LOW

and to change the bank definitions (bf_bank_gpio) to the ones for BFSB i.e.

Code:

static const int bf_bank_gpio[BITFURY_MAXBANKS] = {18,23,24,25};

Allright, now it's working, thanks. Speed average 151 GH/s with the default chip speed of ~~42 i assume? How does this setting correlate to setting 54 in best.cnf for example?~~ 54, scrolled down on the code Roll Eyes

Also i got the segfault by trying to set --bitfury-clockbits 0:55,1:55,2:55... etc. Seems the arg parsing fails? I do have ulimit set to unlimited, but all i get is this:

I'm running cgminer through shell scripts, should i run it directly to get the coredump?
