Boot Process

The code has a bootloader which loads the executable program from the SD card. The bootloader code runs from ROM on the FPGA.

SD Card Image

The SD Card contains a single file, boot.sre . This file is run automatically when the card is powered on.

The image is an S record. The SD card is a FAT32 formatted card.
