How to download BIOS source code

git clone https://github.com/cixtech/bios.git -b cix_p1_community_dev ${YOUR_WORKSPACE} --recursive

How to build (X86 Linux Environment)

From ${YOUR_WORKSPACE} run the following commands to download tools and setup environment:

ln -s cix_package-tool/cix-build.sh cix-build.sh

mkdir tools
cd tools
git clone https://github.com/acpica/acpica.git --branch R2024_12_12

mkdir gcc
cd gcc
wget "https://developer.arm.com/-/media/files/downloads/gnu-a/10.2-2020.11/binrel/gcc-arm-10.2-2020.11-x86_64-aarch64-none-elf.tar.xz?revision=79f65c42-1a1b-43f2-acb7-a795c8427085&rev=79f65c421a1b43f2acb7a795c8427085&hash=D1F7530466A8D7D3C25BA1D7D82C743C" -O gcc-arm-10.2-2020.11-x86_64-aarch64-none-elf.tar.xz

tar -xf gcc-arm-10.2-2020.11-x86_64-aarch64-none-elf.tar.xz

cd ../..

./cix-build.sh

Found "cix_flash_all.bin" and "SKY1_BL33_UEFI.fd" in output folder

How to Change OEM Key for sign ATF, TEE and UEFI code

1. Directly replace OEM private key and pubic key in cix_package-tool/Keys Or Customize sign process in cix-build.sh

2. Run build script cix-build.sh to re-generate new binary

How to Flash Firmware

1. Use SPI Flash Programmer(like DediProg SF100) by flash file "cix_flash_all.bin"

2. Run FlashUpdate.efi(edk2-non-osi/Platform/CIX/Sky1/FlashTool/FlashUpdate.efi) under UEFI shell For Example:

FS0:\>FlashUpdate.efi -f cix_flash_all.bin
