[edk2] Supporting 2nd HDMI port for Intel Atom Bay-Trail (E3800)?

We have a new Intel Atom E3800 (Bay Trail) based board with 2 x HDMI ports. We are using the edk2 firmware (used the minnowBoard MAX firmware source as basis) but we can't seem to get the HDMI-2 port to be recognized by either the firmware or our linux kernel (built with yocto project - kernel version is 3.19.5).

Can anyone give me some pointers as to what we need in either/both firmware and linux kernel to get the 2nd HDMI port to be enumerated/recognized?

Thanks!

What version of the MinnowBoard MAX sources did you start from? According to the release notes, there were changes made on the 0.80 version release to support Dual-HDMI display outputs.

If the firmware is based upon an earlier set of sources, then it will probably not have those changes, which seems to be appropriate to your goals. If you are using the 0.80 or later sources, then it will require a more technical and specific of discussion.

Hi Michael,

Thanks for your fast response! My humble apology - I should have mentioned
the firmware version we started with!

It is 0.81 (which is the latest version as far as I know).

Thx

Gerard
