Installation notes
The Toshiba AC100 used to ship with Android 2, the fastboot bootloader and a custom partition table format. Nowadays, you can install U-boot on it. It is advisable to make a back-up (documented elsewhere; you'll need nvflash as documented below).
In order to modify the operating system, you need to connect the AC100 with a mini-usb cable to an Intel system we'll call the host. On the host, build the nvflash tool:
pkgs.stdenv.mkDerivation {
name = "tegra-driver-package";
version = "r16.5.0";
src = pkgs.fetchurl {
url = http://developer.download.nvidia.com/mobile/tegra/l4t/r16.5.0/ventana_release_armhf/Tegra20_Linux_R16.5_armhf.tbz2;
sha256 = "11qmqj0yillwfapzcfjr4px4z8l7zkh0v3xrfpr9riff54xsidq2";
};
configurePhase = "";
buildPhase = "";
checkPhase = "";
installPhase = ''
mkdir $out
cp -r * $out/
'';
}
Build the nvflash tool and follow the instructions for installing U-boot starting with the getbct.sh step at https://paz00.ru/index.php/Migrate_to_U-Boot#With_prebuilt_sosuboot-tegra_archive_or_sdcard_image_.28PC_not_required.29
When U-boot is installed, proceed with the sd-image-armv7l-linux.img image from https://www.cs.helsinki.fi/u/tmtynkky/nixos-arm/installer/ and follow the general NixOS installation instructions. If the first installation attempt fails, you will need to use the U-boot command line to select an alternative installation medium, using something like (please correct):
setenv boot_targets=usb0
run distro_boot
