Windows, really? Talking about a flaky OS and let¹s not talk about all those patches that I have to wait 5 or 15 minutes every day when I boot and then when I shutdown and all those reboots for upgrades. Windows is a piece of crap, period. I only use windows because some of the tools I use only run on Windows, but if I could ditch it, I would. I use OSX and everything just works. One of these days I¹m going to get the Linaro ARM cross compiler working and then I¹ll ditch Ubuntu as well. I dont recall what the topic was of the Video, but if you search youtube for Linus torvalds + F*** nVidia . . . Yeah lets just say you might be mildly amused. nVidia in the past and probably still does not play nice with the open source community. I changed from ATI because of driver issues and nVidia open source driver works find with Ubuntu. As far as the older kernel goes. Debian is known to move slower and more purposeful when compared to other distro;s. And as a result is generally very, very stable. However, because of this, also generally you need to pay attention to supported hardware. You are right about this, Debian is rock solid. I did try the testing repo and that looks pretty stable as well. My only hesitation is that I¹m not that familiar with all the repos I need and I don¹t have the time to research this right now.

Re: [beagleboard] path of least resistance to Debian
Sorry I missed a question. There are a couple ways to view cross compiling versus compiling native. In the end though it is up to you whether one way or another is better. For example, it might be quicker to cross compile the dependencies for Node.js, etc. But setting up the environment for such may be more pain that it is worth. Myself, I chose to compile natively in this instance, even though the compile took around an hour. Mostly due to my own lack of knowledge on a few different aspects of this process. One thing you will probably never want to compile natively is the kernel. But again, that would be your call. Anyway, the really cool thing about my own setup is that I run my rootfs from an NFS share. One of the cooler things this enables me to do is setup Samba on my support system( instead of the BBB ) to share directories / file out on. Then I edit source code via my text editor of choice on my own desktop ( Win 7 x64 enterprise ) . After whcih i can compile natively on the BBB, or cross compile on my support system. I even have the Linaro binaries for Windows to cross compile from my desktop when I feel like it. Now someone like Robert would probably say something like Just spend ~$200 on a quad core dev board with 2GB RAM, with SATA, and compile natively . . Which i have to admit sounds pretty cool but . . .I can not justify the costs personally just yet.

[beagleboard] path of least resistance to Debian
I am fairly certain that this has been answered but I have spent the last two hours perusing the Wiki, the website, and the forums looking for a definitive path to move my BBB from Angstrom to Debian. I am left with some questions which I am pretty certain someone has already answered but I still need pointers. 1. Is it better to run Debian from MicroSD or from the eMMC? 2. My native OS environment is MacOS. I have decompressed both Debian images on my Mac. For the MicroSD it seems the easy way to write the image is with dd using a 512-byte blocksize (one sector), right? 3. Is there a way to write the eMMC image from MacOS? I'd rather not have to boot up Windows if I can avoid it. (After all, we are trying to run linux and having to run Windows in order to do maintenance on a Linux system just seems ... wrong.) 4.

Plus it doesnt hurt to run from the sd card, unless you do not have a uSD card + sd card adapter, and do not care to spend money on this. I have a 16GB uSD card to run from. Just wondering what the pros and cons are. Seems that the cons are worry that the eMMC will reach its write limit. I don't think that will be an issue for my application as I intend to use the BBB as an embedded system. (See below.) #2 I'll defer to someone else, as I am not a MAC person. Mac is just FreeBSD once you are in the shell (for the most part). There are worse places to be. ;-) There are some incompatibilities with OSX, but if you use ³MacPort² or ³HomeBrew² or ³Fink² to get the GNU tool versions. Since the GNU version are the same as Debian or Ubuntu, the same instructions will work on Mac. #3 NO idea where you got this impression. All the instructions I've seen are *NIX based, and I *DO* personally run Windows for my own desktop environment. I couldn't find any instructions other than for doing it from Windows until I was pointed to the Adafruit site. #4 You would have to boot up via uSD to write out the eMMC I believe. I now have Debian running from the uSD card and it is working just peachy. Attempts to copy the eMMC version to the eMMC didn't work but I only want that as a backup to the uSD. Eventually I will probably want to run from eMMC when I close everything up and shove it into a rack. You may want to consider dedicating a machine, or perhaps use virtualbox to have a Debian wheezy i386 support system. This really depends on how serious you are. As an example, I compile my own kernel based on Robert Nelsons instructions, and build a custom rootfs also based on his bare rootfs stuff. Which I mount rootfs over our network ( to prevent me from ruining flash media while I experiment / tweak various things ). Thank you. I may go that route. I have a couple of machines I plan to dedicate to Linux (one is already running ubuntu -- not sure that is going to stay that way). Is there a good cross-development environment or is it just as easy to build on the BBB itself? The only issue preventing me from using OSX for all my BBB development is Linaro does not have a cross compiler for OSX. Also OpenEmbedded/Angstrom/Yocto do not work on OSX. Since running Robert Nelson¹s scripts depend on Linaro, you cannot use his build scripts either. For now I use an Ubuntu 14.04 box. You might want to consider Parallels and install Ubuntu x64 which works great. Regards, John The project right now is turning the BBB into a GPS-disciplined NTP server. The plan is to have a local UTC display (I think Nixies would be cool for that classic retro look but 7-segment LED displays would be OK too and easier to drive) and eventually use it to discipline my Rubidium reference as well. -- Brian Lloyd, WB6RQN/J79BPL 706 Flightline Drive Spring Branch, TX 78070 br...@lloyd.com +1.916.877.5067 tel:%2B1.916.877.5067 -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
