Dear all,

I'm trying to make an old, V1.0 board based on Intron's design which is very similar to BFSB's 450 GH/s miner. It has 16 Bitfury on a card and 16 card slots, the only difference is that instead of having an I2C selector for which card the SPI bus should talk to, it has a long chain of 16*16=256 Bitfury chips and it's attached to a RPI SPI port.

I modded the driver-bfsb.c file in order to scan only for one slot (the first and only, which is supposed to have 256 chips) but only 99 chips are detected! I tried to swap slots, use spare cards but nothing, the autodetection always stops at 99 chips. It is driving me crazy because there doesn't seem to be any "maximum chips" constant neither in the libbitfury.c nor in driver-bfsb.c, so I can't find where this limit comes from!

Can anybody help me or suggest me where to look at or had a similar problem?

Thanks in advance!
