Bootloader and SD Card

A project log for 68K CPU with Frame Buffer on FPGA

Working with AMR's build and improvements to the TG68 FPGA project 01/16/2021 at 14:080 Comments

Boot Process

When AMR code runs it loads the executable program via a bootloader from the SD card. The bootloader code runs from ROM on the FPGA.

SD Card Image

The SD Card contains a single image, boot.sre . This image is loaded by the bootkiader when the card is powered on (or reset) and run automatically.

The image is an S record.
