I just got the UDOO Quad the other day and so far I'd say I prefer the debian variant the most. There are a few problems/questions I have though - note that I have tried linux on 3 other ARM platforms. 1. Is there a way to edit uboot using a boot partition, and is there a sample mkimage script I can generate? I saw the Arch instruction on it, but it's very vague and doesn't explain whether or not it uses a boot partition 2. Why am I not able to mount the SD card on another system? I seemed to get this issue with ubuntu and debian specifically, though Arch never had this issue. 3. The display works fine, but it's stuck at 1080p when my display is 1366x768. The image is basically scaled down, but it's a little blurry because of it. Is there a way to force the screen resolution to be smaller? I'm sure this would be doable if there is an answer to my first question. 4. I heard the Freescale CPUs have OpenGL support as well as GLES, but glxgears fails. Any ideas? 5. I have a USB touchscreen panel (eGalax) which works on other ARM platforms, but not the UDOO. I installed the official drivers for it (which work with the 2.6 kernel and higher) but that didn't help. What I find particularly strange about this touch panel is I have an x86 Arch setup that doesn't have the drivers for it but it works anyway (unless the open source drivers were included in one of the newer kernels) 6. And that leads me to my last question - any news on running a kernel newer than 3.0, preferably with working video drivers? Doing so may fix my problem #5. If upgrading to debian jessie is known to solve any of my problems, I'm definitely willing to make the upgrade. I appreciate any answers, I know this is a lot to ask.
