Installation

Device comes stock with coreboot and depthcharge. depthcharge is annoying to work with in my opinion, so I recommend working around it to get u-boot loading somehow so you have a sane normal bootloader. There are two ways to accomplish this, either flashing u-boot to spi and getting rid of depthcharge completely, or chainloading u-boot from depthcharge.

chainloading

Chainloading is safest with no chance of bricks, if something goes wrong you can just restore using the chromeos recovery image. will write instructions later

u-boot on spi

My preferred method, but with some chance of brick.

$ git clone https://github.com/u-boot/u-boot

$ make -j8 O=b/chromebook_jerry CROSS_COMPILE=arm-none-eabi-    chromebook_jerry_defconfig all

$ ./b/chromebook_jerry/tools/mkimage -n rk3288 -T rkspi  -d b/chromebook_jerry/spl/u-boot-spl.bin spl.bin &&    dd if=spl.bin of=spl-out.bin bs=128K conv=sync &&    cat spl-out.bin b/chromebook_jerry/u-boot-dtb.img >out.bin &&    dd if=out.bin of=out.bin.pad bs=4M conv=sync

// copy out.bin.pad to chromebook
$ sudo flashrom -p linux_mtd -w out.bin.pad
