|
|
./usb-flasher/ppkb-flasher info > saved-info.txt
|
|
./usb-flasher/ppkb-flasher --rom-out saved-rom.bin read
|
|
|
|
# build the new firmware (you may need sdcc 4.1, older versions may
|
|
# miscompile the firmware)
|
|
|
|
(cd firmware && ./build.sh)
|
|
|
|
# flash the new firmware
|
|
|
|
./usb-flasher/ppkb-flasher --rom-in firmware/build/fw.bin write reset
