jstefanop wrote a new firmware for the Spartan Chip (it costs 20 Bucks) and wrote an driver for bfgminer. It works realy good. I have avg. <0.5% rejected and <3% HW on the most pools. Sometimes you have to playing with settings. Very fast coinswitch and low coin difficulty are an problem also after flashing, but not so heavy. Use pool instruction for KNC Titan, it works very well for MAT too!
But with the flashing the MAT are usable
You need
- Raspberrypi 2 (B+) [Raspi 3 dont work!]
- short Cable for pins
- Flashfile from jstefanop
- reading this instruction Original Litecoin Thread
You can clone luke-jr bfgminer and not jstefanop git, the driver is now in lukes git
Hurdles:
- By cloning github certificates error, use the ca-validaty ignore command.
- Restart the Raspi after every well done flashing
- Not decting chain -> clean with wodka the pins before pin in, just so that not make dirty contacts inside
- Error while flashing -> try it few times, reboot, clean, try again few times... If it dont work, than this hashboard may have issue
- if you root, change directony in /home before cloning otherwise you to login for ever with root to use bfg...
- if bfgminer cant found board, than you have to stop the Pythonminer in the GUI or rename the MAT folder.
- If bfgminer cant found board and pythonminer is disabled, than plug out the electric cables and give electricity first to the board and at least to controller.
I have flashed five (two my own, other for friends) M.A.T, it works!
(Please dont missunterstand! I dont want make promotion for jstefanop and i get nothing for it! I have spent very much time for searching and making and in past i would be very happy if someone tells me straight this solution for the rejected issue)
