this is the link to download kernel headers for 2.6.22.18

]]> Comment on Sheeva Plug as a MythTV master backend by puterboy http://computingplugs.com/wp/?p=81&cpage=1#comment-3337 puterboy Mon, 31 Jan 2011 03:23:54 +0000 http://computingplugs.com/wp/?p=81#comment-3337 Have you considered using the GPlug-Display as a myth frontend? It is also a plugcomputer made by GlobalScale (the same company that makes the Sheeva Plug) BUT it has a built-in HDMI video capability and output. I think the best it can do is 720p but since I believe the decoding is done in hardware it may work nicely for a frontend. In fact, what could be a better than a small 7W plug that plugs directly into an HDMI input on your flat screen. Have you looked into this device? (it's new and may not yet be shipping commercially but I received a sample and it's pretty cool) Have you considered using the GPlug-Display as a myth frontend?

So far so good. I made the following notes in the process: (1) I had to edit the kernel Makefile for local compilation. I commented out the lines that specify the cross-compile "arm-none-eabi-" prefix and the "arm" architecture. (2) I couldn't find a "kirkwood_defconfig" file, I specified "make mv88f6281_defconfig" instead. I’m currently compiling the 2.6.2.18 kernel on my SheevaPlug. So far so good.

Would it be possible to see benchmarks comparing the various kernel versions, especially for encryption using the hardware SSL capabilities.

I was hoping to avoid the hassle of compiling my own kernel; I have a driver module I wanted to compile, but it's looking for a /lib/modules/2.6.22.18/build directory that simply doesn't exist. Looks like I'm missing the kernel headers from the build they did corresponding to the 2.6.22.18 feroceon kernel. Does anybody know of an archive of just those headers? Access to them would save me a lot of time. Thank you for these excellent directions; this looks like it should work for me!

Then restore the router settings from this file and voila... now you can use any web service like http://www.depicus.com/wake-on-lan/woli.aspx or a program to do your wake on wan. if you have any doubts you can email me at aldiablo [at] gmail.com Dakkar to enable wake on lan on belkin router you need to use the port forwarding section to forward paquet 9 UDP to the broadcast address of your network e.g. (192.168.2.255) the belkin router wouldn’t allow you to do this but here’s the trick ;)

I have had a hard time to get anything up and running - finally got something going with Debian. This website seemed very promising. However, when booting the uImage.sheeva.040309 I get silence. Nothing at al - need to reset. Questions: 1) is something in the NAND flash needed for the above to work? I have not been able to find out how to set the NAND with mtdparts configuration 2) which filesystem - where to download for the above guidance?

2) which filesystem - where to download for the above guidance?

Actually in the log I see error at update like Error mmaping file /xxx/xxx/xxx.rrd ': Invalid argument If I look at the generated files and graph I have only NaN values. Did anyone get this problem ? I tried to compile rrdtool from source but got the same behavior. Hello,

I did some measurements myself this spring but did not get to put them on my blog, since I did not measure disk performance and network performance. Well, now I decided to put them out anyway at http://martin.feuersaenger.de/2010/09/21/benchmarking-the-sheevaplug-on-nfs-performance/ They pretty much confirm for NFS performance, what you meausred, Kenny. I also found fragfutter's measurements. I guess I have to redo my analysis with a newer kernel version, once I have replaced the fried PSU of my Plug ;-) Nice work, this page.
