I cannot get any video output on my Efika MX using the available images, this is what I did so far:

I have extracted installer-sd.img.lzma (2009-12-22, 158 MB, LZMA archive) to a 4 GB SD card, fdisk'd the last partition so that it uses the complete card, resize2fs'd it.

apt-get updated, upgrade, install ubuntu-standard, then ubuntu-desktop.

Extracted this into the root: imx51-gpu-bin-2.6.31.tar.lzma (2010-04-05, 2 MB, LZMA archive).

Note the monitor goes non-detected. I have tried two HDMI to DVI cables.

Looking further, but if anyone recognizes a problem, pls. let me know.

Detection fails, but have video now.

I have switched to another screen, and now I do have display, but the monitor (EDID) detection still fails.

Might this be related to my version of u-boot (developer edition MX box)?

Anyway, my previous Dell 2007WF(Pb) Rev. A4 didn't seem to like 1280x720x60, although it can natively handle up to 1680x1050x60.

Switched to a Dell U2410, which wasn't detected either, but showed a nice picture.

Leon.

New U-Boot and new Kernel would probably do you the world of good. Older U-Boots may not be setting the regulators up properly for certain parts of the chip, in which case you see weird i2c bugs like this pop up.. you're also running the DDR bus at 166MHz instead of 200MHz so you're not seeing the full performance.

There's no difference between the Projects and Store Efikas (they're all Board Rev. 1.1) except Projects went out first so they may not have had the Genesi-updated U-Boot on them (which is why it says LANGE51 which is Pegatron's name for it..)

The 1.1.8 U-Boot on the Efika MX Firmware page is probably your best bet, I am currently working on a mainline U-Boot port which should be pretty excellent and represent the end of our U-Boot support (since it'll go mainline, and the hardware isn't changing..) and a new kernel (with a pretty new graphics driver).

This is a lot of work so it's going to take a while, but what is there.. works just fine.
