This repo contains the tools necessary to build the TinyLlama BIOS (Coreboot/SeaBIOS).
Based on the 86Duino project from https://github.com/roboard/build-coreboot
Tested on:
- Ubuntu 16.04 i386
- macOS Big Sur x86_64
- macOS Monterey x86_64 and arm64
Other operating systems and architectures are probably easy to get working as well, but your mileage may vary.
Install various tools:
$ sudo apt install git build-essential m4 bison flex python texinfo gnat
For Apple Silicon (arm64) CPUs, look here.
- Install Homebrew:
$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
- Install gcc version 6:
$ brew install gcc@6
$ ln -s /usr/local/bin/gcc-6 /usr/local/bin/gcc
$ ln -s /usr/local/bin/g++-6 /usr/local/bin/g++
- Install gnu-tar and wget:
$ brew install gnu-tar wget
$ ./build-xgcc.sh
$ make
If building is successful, the 1 MB output ROM file will be in the out/ directory.
Another file is also made - out/xxx-padded.rom - padded with 0xFF to fit 8 MB, for flashing directly to the SPI ROM using a hardware programmer. The Coreboot/SeaBIOS ROM will be located at the end of this 8 MB file.
