<div dir="ltr">Hi Jon,<div><br></div><div>On our skype call yesterday, I learned that Tim probably will not get his Cubox's in time (we need at least 2 for the Cubox to be a viable test case). So my sense of urgency is much diminished.</div>
<div><br></div><div>Progress report -- mostly as a log because the hardware seems really promising and I expect to be coming back to Cubox later in the year. When I was doing yum updates of the rootfs, top reported 100% utilization for the yum task, but also 75% idle on the summary panel.</div>
<div><br></div><div>I was abe to get uEnv.txt to change the commandline for the kernel, as verified by "cat /proc/cmdline". But still could not get the frame buffer and XFCE desktop settings to work together for the GUI console (640x480 resolution was usable, but a little awkward). I did a little googling, and after trying your video command line args, I tried "video=mxcfb0:dev=hdmi,1024x768M@60m" . I gave up on this task because ssh into the device is what I usually do anyway.</div>
<div><br></div><div>On the Cubox, I groupinstalled "Development Tools", and compiled the modeules, and did a "make install". This operation did not set up /lib/modules/<kernelid> properly, so I reached the extent of my comfort area. I was not able to get the esata enclosure (startech model:sat2510u2e) to be recognized. No idea of how much word is involved there.</div>
<div><br></div><div>I could go back and try to get Rabeeh's kernel to load and run. It's about 30Mb, whereas mine turned out to be only 4MB or so. I guess he put everything in the kernel. I suspect the the load adress needs to be jiggled for his kernel to run.</div>
<div><br></div><div>I used uEnv.txt to modify the u-boot environment variable: mmcargs, and mount an external usb SATA drive as the rootfs. (so the load process took the kernel from mmcblk0p1, and mounted /dev/sda1 as /.</div>
<div><br></div><div>As I was trying to load the XSCE software, I found that I needed a second ethernet adapter, but neither the Cubox, or the trimslice which I use as tool, seems to have drivers for the <span style="color:rgb(0,0,0);font-family:'Arial, Helvetica, sans-serif';font-size:13px">AX88772 USB to 10/100 Fast Ethernet/HomePNA/HomePlug controller. I'm sure there are other adapters which the kernel can handle, so I stopped on this track.</span></div>
<div><span style="color:rgb(0,0,0);font-family:'Arial, Helvetica, sans-serif';font-size:13px"><br></span></div><div><span style="color:rgb(0,0,0);font-family:'Arial, Helvetica, sans-serif';font-size:13px">In a way, I'm relieved that all of this doesn't need to be done and tested before we leave on Jan 17. But I'm hopeful about Cubox. I'm just not sure about the industrial design, the packaging, the way to make the interconnects reliable and robust. I found the console usb serial connector interferes with the USB connector above it, and makes the console connection problematic.</span></div>

<div dir="ltr">George,<div><br></div><div>Start out running the u-boot and kernel that Rabeeh has provided, that is based on the current "stable" kernel sources provided by Freescale. I have a 3.10 based kernel that is more performant but I have not run it on the i4 hardware yet. Getting a baseline on the standard we can then better diagnose bugs or performance issues one way or the other with the new kernel. For the second partition feel free to untar the F18 armhfp base image. Changing the kernel command line can be done using a uEnv.txt file on the first partition of the SDHC port. If we need anything more advanced I can write a u-boot boot script, or custom u-boot to handle loading things. We may want a "fallback" kernel or something similar.</div>
