Re: [coreboot] intel atom e3815

John,

One 'gotcha' of  the Minnowboard Max to look out for is based on a GPIO (jumper setting) it will override some of the DRAM settings that you put into your FSP. You probably do not want that. I found it better to use the Baker Sport for ECC designs or the Bayley Bay for non-ECC designs as a starting point with custom hardware.

There are a lot of things to consider when trying to boot this chip. One thing I learned the hard way is you do not have to cover the images on the E3800 family (Baytrail-I) and it will boot without the TXE image in the boot flash. But if you leave the TXE out the XDP port is disabled.

Hi John,
coreboot does support the E3815 (Bay Trail I) with the Intel FSP.
The tree is a little broken for it right now, but we're working to get
it fixed. The primary example for that chip is the Minnowboard Max.

A couple of resources to get you started:
- http://intel.com/fsphttp://intel.com/fsp - There are a number of cocuments in the
"Intel Atom processor E3800 product family" section that would apply
here.
- http://www.apress.com/9781484200711?gtmf=shttp://www.apress.com/9781484200711?gtmf=s - The Embedded Firmware
Solutions book talks specifically about this family of chips

If you have any questions about how to get started, the best place to
get support might be the coreboot irc channel - #coreboot on
freenode.nethttp://freenode.net.
