||||
If you have the SD bootloader already installed:
|
||||
1. Copy femu.bin to the root directory of your SD card, and insert it into Floppy Emu.
|
||||
2. Hold down the PREV and SELECT buttons.
|
||||
3. Press and release the RESET button.
|
||||
4. Follow the on-screen prompts.
|
||||
|
||||
If you don't have the SD bootloader installed:
|
||||
1. Use your AVR ISP programmer to flash floppyemu.hex to the microcontroller.
|
||||
|
||||
If you want to install the SD bootloader:
|
||||
1. Use your AVR ISP programmer to flash merged.hex to the microcontroller.
|
||||
2. Use the ISP programmer to set the BOOTRST fuse to 1 (on), and the BOOTSZ fuse to 2048W_F800. (Fuses should be Extended: 0xFF, High: 0xDA, Low: 0xBF)
