@ -17,6 +17,11 @@ C source is included for a bitforce firmware flash utility on Linux only:
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
It takes a bit under 3 minutes to flash a BFL and shows a progress % counter
