Re: [CLOSED] Bitmine CoinCraft A1 28nm chip distribution / DIY support
Finally!!!
Test vectors passed
And I can confirm now that test job returns six nonces. 744ec1ec is the 6th one.
This chip is a nightmare for software writer. Behavior of the chip depends on the command. Some commands break chain, some don't return any value back to host uC. And datasheet is the worst I ever seen. Errors (register table for example) and lack of information. Without oscilloscope I would never guess how to "talk" with this chips. Many hours spended on discovering things that should be in datasheet.

I don't get it, doesn't this driver: https://github.com/ckolivas/cgminer/blob/master/driver-SPI-bitmine-A1.c cover the communication with the A1 chip?
Are you saying that there is something wrong with the driver?
