The OpenMoko phone ;-) Unfortunately the project is implemented in Java, which I'm no fan of on anything but a web server or browser but that's a discussion for another day. I tried our system, which is running in an OSGi Container, on Jamvm on the OpenMoko. It works but it sucks up 95% of the CPU when it's idle. Not Good! I tried the same on my eeePC and with Sun's JRE our system uses 1% of CPU whilst JamVM on the eeePC uses 40%. Obviously JamVM does not suit our system. No idea if it would be better, but have you tried cacao? Its in shr-feeds now again. This is really weird! I wrtoe one more or less serious app in java for the freerunner and a couple of test apps and jamvm had avery fast startup, but was not as compatible as cacao, but easier to use and did not require that much ressources. which distro are you using? which feed are you using to install jamvm (dunno if still true but there used to be a difference depending on where you installed it from). Sorry I've been a bit busy on stuff and only now catching up here on the list. I'm using the latest classpath 0.98 and Jamvm 1.5.3 I can't remember the specifics at the moment but there was some feature of Java 6 that our system's code was using which required JamVM 1.5.3 which in turn required Classpath 0.98. I just used a OE recipe for those and build them for the OpenMoko. I tried the Cacao JRE on my eeePC and it soaked up resources as well so I never even bothered to build it for the phone. Obviously something in our Java System, mabe knophlerfish is not streamlined in these JRE's. There is a Huge difference in running our system in a SUN JRE (1% CPU According top) and other Jre's I'm working now on the eeePC to see can I reduce this 40% on Jamvm. When I get time actually I'm now trying to connect to an AdHoc wifi network form the FreeRunner. Thanks for the clarification on the ARM front. I don't think Sun have a JRE for an ARM 4, no surprise really ;-) Things would be too easy. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community I think that OpenJDK has some JRE machines running on ARM. It's no receipe in OE yet, but i tested a GUI in a OE machine and worked fine. I didn't test the load of the CPU, but i could tell that some JREs are working. I hope to post some of this in OE repos, and get a OpenJava JRE machine :) -- ___ Rafael Campos o0 Methril 0o http://openblog.methril.net/ ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
[shr-latest] question on upgrades
Hi guys, great work on latest shr! It works like a charm for me (btw i still don't use fr as a phone), there are few glitches but this is not what this post is about. Do you recommend to updateupgrade or this is going to brake the distro? d ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Newbie - Installing SHR on FreeRunner
Hi folks! To make it short. Let me know if this is the wrong lists to post following question. Perhaps you can point me to the right list? I just recently bought a used FreeRunner. And now I want to play around, especially I would like to try out different distributions. When I got it, it had hackable:1 on it. Now I'm trying to install SHR on it. I found a description for the installation process here: http://wiki.openmoko.org/wiki/SHR_User_Manual It seems I didn't get it right. I downloaded the uSD card image. I was able to write is on the uSD card and I also could boot the first time. After a reboot, it stucks, saying: Unknown boot option `g-ether.host_addr=00:1F:11:01:0B:A3`: ignoring I *think* I was supposed to unpack the kernel and the modules too. Perhaps I also had to use `dfu-util` to write a new bootloader. However, what I'm trying to say is that the documentation is not that clear to me in that point. Since I want to use a uSD card, I concluded that I had to download uImage-xx, `full-om-gta02.tar.gz` and finally the modules. The big question mark I have is when to apply the modules? Shouldn't I unpack them on the uSD card too? The documentation is mentioning to unpack them on the FreeRunner. Isn't it then too late? For me it would be a good help to have a step by step tutorial with as few ifs as possible. Can somebody give me a hint to such a tutorial? Don't get me wrong, I'm happy for any documentation! I know how it feels to work on assumptions how things work. I'm grateful for any hint! Looking forward to continue tweaking my little device. :-) Joerg ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

It's not the wrong list, but shr has it's own user[1] an devel[2] list, so it might be a good place to ask if you cant's find all the help here. I just recently bought a used FreeRunner.

After a reboot, it stucks, saying: Unknown boot option `g-ether.host_addr=00:1F:11:01:0B:A3`: ignoring what image are you using? I'm not an expert on shr but shr-testing[3] is working fine for me so far (they just release it a couple of days ago, and shr-unstable[4] from november 30th it fine as well. Just be careful about using the right modules for the kernel. I *think* I was supposed to unpack the kernel and the modules too. Perhaps I also had to use `dfu-util` to write a new bootloader. However, what I'm trying to say is that the documentation is not that clear to me in that point. Since I want to use a uSD card, I concluded that I had to download uImage-xx, `full-om-gta02.tar.gz` and finally the modules. As you know you have to options: flash the kernel an image into the internal flash of the neo, and the other one is use an micro sd card. I myself prefer to do all the testing into the sd card an just flash a light and not pimped distro into the phone. The only reason is that untarng into the sd card is faster than flashing. If you flash you use dfu-utils, and flash the kernel an the image, start the neo, then log in via ssh, copy the modules an untar them into the / If you use the sd card you create (at least) two partitions and put the kernel (uImage.bin) in the first and the uncompresed image and modules into the other one. It normal if it takes longer to boot the first time, but it should take 1 2 minutes to boot the next time. The big question mark I have is when to apply the modules? Shouldn't I unpack them on the uSD card too? The documentation is mentioning to unpack them on the FreeRunner. Isn't it then too late? Noup, not too late. Modules are an optional thing to do. It should boot without them most of the times. For me it would be a good help to have a step by step tutorial with as few ifs as possible. Can somebody give me a hint to such a tutorial? The link you mentioned above and this[5] are supoosed to do that. Sorry it didn't. I might take a look at that, but my english is no that good and It could get a lot worse :p Don't get me wrong, I'm happy for any documentation! I know how it feels to work on assumptions how things work. I'm grateful for any hint! Looking forward to continue tweaking my little device. :-) Good look!
