A misleadingly-named Tegra X1 Boot ROM exploit and Nintendo Switch Linux loader.

If your Switch catches fire or turns into an Ouya, it's not our fault. It's stupidly easy to blow up embedded platforms like this with bad software (e.g. all voltages are software-controlled). We already caused temporary damage to one LCD panel with bad power sequencing code. Seriously, do not complain if something goes wrong.

On the other hand, this exploit probably works on the Ouya...

You need arm-linux-gnueabi and aarch64-linux-gnu toolchains.

Clone everything:

$ git clone https://github.com/fail0verflow/shofel2.git
$ git clone --recursive https://github.com/fail0verflow/switch-coreboot.git coreboot
$ git clone https://github.com/fail0verflow/switch-u-boot.git u-boot
$ git clone https://github.com/fail0verflow/switch-linux.git linux
$ git clone https://github.com/boundarydevices/imx_usb_loader.git

Build the cbfs loader:

$ cd shofel2/exploit
$ make

Build u-boot:

$ cd u-boot
$ export CROSS_COMPILE=aarch64-linux-gnu-
$ make nintendo-switch_defconfig
$ make

Build coreboot:

$ cd coreboot
$ make nintendo_switch_defconfig
$ make iasl
$ make

Build imx_usb_loader:

$ cd imx_usb_loader
$ make

Build Linux:

$ cd linux
$ export ARCH=arm64
$ export CROSS_COMPILE=aarch64-linux-gnu-
$ make nintendo-switch_defconfig
$ make

Run the exploit

$ cd shofel2/exploit
$ ./shofel2.py cbfs.bin ../../coreboot/build/coreboot.rom

Build the u-boot script and run it

$ cd shofel2/usb_loader
$ ../../u-boot/tools/mkimage -A arm64 -T script -C none -n "boot.scr" -d switch.scr switch.scr.img
$ ../../imx_usb_loader/imx_usb -c .

If all went well, you should have some penguins. You should probably put a root filesystem on your SD card. Arch Linux ARM provides ready-made rootfs tarballs that you should totally use. Userspace libraries and other patches coming soon.
