SpacemiT Firmware

This repository contains binary firmware files for SpacemiT SoCs.

DDR Training Firmware

ddr_fw.bin is the DDR memory training firmware. It is loaded and executed by U-Boot SPL during early boot to initialize DRAM.

Usage

Pass the firmware path via the DDR_FW_FILE environment variable when building U-Boot:

export DDR_FW_FILE=/path/to/spacemit-firmware/<soc>/<version>/ddr_fw.bin
make <board>_defconfig
make
