I need some help from here.
After upgrading my S1 hardware to S3 with the kit, I now have several boards from the S1 with the BM1380 chip that I would like to undervolt and stick in a hashing rig, but I need to interface with the rig.
Thus far, I have connected a board using USB->TTL dongle and can send data accross and receive responses from the board. I have to state here that the data sent is a string of a generated target that I got from cgminer debug output, i.e
[2014-09-23 16:38:05] Generated target 0000000000000000000000000000000000000000
0000000000f0ff0f00000000
PS. I only send everything after the word
target!
The response I get from the board is this:
59-57-4B-59-867C12-F6-58-865957-4B-59-867C12-F6-58-865957-4B-59-867C12-F6-58-865957-4B-59-867C12-F658-865957-4B-59-867C12-F6-58-8659-57-4B-59-867C12-F6-58-865957-4B-59-867C-12-F6-58-865957-4B-59-867C-12-F6-58-865957-4B-59-867C-12-F6-58-865957-4B-59-867C-12-F6-58-8659-57-4B-59-867C12-F6-58-8659-57-4B59-867C-12-F6-58-8659-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-86-59-57-4B-59-86-7C-12-F6-58-8618-68-BD-2F-98F0-B2-10-31-9292-34-E4-99-926BE5-E0-98-92BD-5A-95-67-92F0-B2-10-31-9292-34-E4-99-92-6B-E5-E0-98-92F0-B2-10-31-9292-34-E4-99-926B-E5-E0-98-92BD-5A-95-67-92F0B2-10-31-9292-34-E4-99-926B-E5-E0-98-92BD-5A-95-67-92-F0-B2-10-31-92-92-34-E4-99-92-6B-E5-E0-98-92-BD-5A-95-67-92-F0-B2-10-31-92-92-34-E4-99-926B-E5-E0-98-92BD-5A-95-67-920C-D9-5D-D7-8556-E9-1E-46-850C-D9-5D-D7-8556-E9-1E-46-850C-D9-5D-D7-8556-E9-1E-46-850C-D9-5D-D7-8556-E9-1E-46-850CD9-5D-D7-85-56-E9-1E-46-850C-D9-5D-D7-8556-E9-1E-46-850C-D9-5D-D7-8556-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85-0C-D9-5D-D7-85-56-E9-1E-46-85A8-64-D0-C0-989A-6A-45-FF-9604-ED-DA-92-96-9A-6A-45-FF-96-04-ED-DA-92-96-9A-6A-45-FF-96-04-ED-DA-92-96-9A-6A-45-FF-96-04-ED-DA-92-96-9A-6A-45-FF-96-04-ED-DA-92-96
NOTE: I am communicationg over USB (on windows) and send a text string and read / receive a binary response. (Am I doing this correctly?)
Anyone have any idea how to interface with this board, aka sending work to a specific chip etc?
PS. I have looked at the cgminer (and bfgminer) code but can not work out what is in the sendbuffer to initialize or send work to the board. If I can get help with what to send to the board, that will be fab.
