The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!

You probably came here trying to find a small (minutes to hours) and easy task where you can get your hands dirty and get results immediately.

If you're a coreboot or flashrom newbie, this page is for you.

flashrom

A tool to read/write coreboot/BIOS images from/to flash chips.

Add the bus type to flash chip definitions

Go through the list of flash chips in flashchips.c inside the flashrom source. Look for chip definitions which have .bustype = CHIP_BUSTYPE_NONSPI and look at their data sheets. Read the data sheets and try to figure out the flash bus they use (Parallel/LPC/FWH/SPI). Change the bustype field to CHIP_BUSTYPE_PARALLEL etc. and post a patch to the list.

Even a single updated chip helps.

Flashrom#Communication_bus_protocol has a writeup on how to figure out the bus type.

coreboot

I'll skip explaining what coreboot is. The whole wiki is about this topic and I can't summarize it in one sentence.

coreboot v2

The workhorse version of coreboot. Lots of supported boards, but difficult to work with.

TODO: Add easy tasks here.

coreboot v3

The next generation version of coreboot. Few supported boards, still in the design testing phase, easy to work with.
