Chrome EC

The Chrome EC is used in almost all Chrome OS devices, and an increasing number of accessories, like Google's Type C chargers. It is based on the Chromium EC code base.

Building the Chrome EC

Building in the ChromiumOS environment

Getting started building EC images quickly

Building outside of the ChromiumOS chroot

Build requirements

You will need:

  • GNU Make 4.1 (older versions are having trouble with the Makefiles)
  • an ARM cross compiler (I used coreboot's armv7-a-eabi- toolchain)

Patches required

Patching up the code:

Build instructions

Let's go:

$ sudo aptitude install libftdi-dev
$ git clone https://chromium.googlesource.com/chromiumos/platform/vboot_reference
$ cd vboot_reference
$ make
[..]
$ cp build/futility/futility ~/bin
$ cd ..
$ git clone https://chromium.googlesource.com/chromiumos/platform/ec
[..]
$ cd ec
$ CROSS_COMPILE=armv7-a-eabi- HOST_CROSS_COMPILE= make BOARD=chell
[..]
$

Build all boards:

ls -1 board/ | grep -v OWNERS | grep -v host | \
while read n; do
  echo "**************** $n"
  CROSS_COMPILE=armv7-a-eabi- HOST_CROSS_COMPILE= make BOARD=$n -j
done

Issues

Targets not building

  • cr50 (make issue with -C)
  • glados,kunimitsu,wheatley: `memset' referenced in section `.text' of /tmp/cc3Dv6dh.ltrans2.ltrans.o: defined in discarded section `.text' of build/wheatley/RO/common/util.o (symbol from plugin)
  • it8380dev: armv7-a-eabi-gcc: error: unrecognized argument in option '-march=v3m'
  • Not real targets, but in board/: host, OWNERS
