@ -17,6 +17,11 @@ C source is included for a bitforce firmware flash utility on Linux only:
bitforce-firmware-flash.c bitforce-firmware-flash.c
Using this, you can change the bitstream firmware on bitforce singles. Using this, you can change the bitstream firmware on bitforce singles.
It is untested with other devices. Use at your own risk! 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
It takes a bit under 3 minutes to flash a BFL and shows a progress % counter
