bitforce-firmware-flash.c
Using this, you can change the bitstream firmware on bitforce singles.
It is untested with other devices. Use at your own risk!
To compile:
make bitforce-firmware-flash
To run, specify the BFL port and the flash file e.g.:
./bitforce-firmware-flash /dev/ttyUSB0 alphaminer_832.bfl
To flash your BFL, specify the BFL port and the flash file e.g.:
sudo ./bitforce-firmware-flash /dev/ttyUSB0 alphaminer_832.bfl
It takes a bit under 3 minutes to flash a BFL and shows a progress % counter
Once it completes, you may also need to wait about 15 seconds,
then power the BFL off and on again
If you get an error at the end of the BFL flash process stating:
"Error reading response from ZBX"
it may have worked successfully anyway.
Test mining on it to be sure if it worked or not.
You need to give cgminer about 10 minutes mining with the BFL to be sure of
the MH/s value reported with the changed firmware - and the MH/s reported
will be less than the firmware speed since you lose work on every block change.
