Re: [beagleboard] Re: question from a total newbie...

mz, While the subject has been brought up. If you've had any experience with Linux development in the past. This experience would largely be the same. You do not need a cross compiler or 99.9% of what all is out there, and the chances you'll need a cross compiler toolchain, and IDE are near nil.

Re: [beagleboard] Re: question from a total newbie...

Well, there seems to be a lot of confusion between toolchains, which no one really asked or said anything about( I made a passing remark ), Linux kernel, and Linux image. My own idea of what makes a Linux image is a complete "package" that contains bootloader(s), a Linux kernel, and a rootfs(root

Re: [beagleboard] Re: question from a total newbie...

mz: You used the term "transferring the kernel" which set off a discussion. I have been programming on the BBB for several years, and have not had to touch the kernel, which is part of the OS image. Some people want to learn kernel programming. OK . In my case, for any application development I

Re: [beagleboard] Re: question from a total newbie...

Not only that but if you make a mistake, and render the eMMC unbootable. How would you fix it without an sdcard ? Short answer is that you can't. But with an sdcard, you'd insert the "emergency" card, revert the changes you made, then power cycle the board ater removing the sdcard. viola! problem

Re: [beagleboard] Re: question from a total newbie...

One more thing, sorry . . . multi-tasking. . . As Graham mentioned above. You'll probably want to start off with a Beaglebone black RevC. But my motivation in recommending this would be slightly different. I've been using an A5A for over 3.5 years, and in the last 1.5 years have been mostly using

mzimmers, Do yourself a favore and get this book: https://www.amazon.com/Exploring-BeagleBone-Techniques-Building-Embedded-ebook/dp/B00QMIYWQM It's probably not the best book for the experienced, or "Expert". But for someone new to this particular discipline. It'll be more information than you

[beagleboard] Re: question from a total newbie...

Thanks for the detailed answers. Do I really need to use an SD card for transferring the kernel to the beaglebone? Seems kind of cumbersome, so if there's another way to do it, I'd appreciate hearing about it. mz -- For more options, visit http://beagleboard.org/discuss --- You received this

Re: [beagleboard] Re: question from a total newbie...

Hi William: For an expert, you are totally correct. For a newbie, the Raspberry Pi images seem to be designed to limit how much tinkering you can do with Linux itself. The tools and examples for modifying Linux itself are much better supported on the Beaglebone. Both are good for blinking LEDs

Re: [beagleboard] Re: question from a total newbie...

By the way, just for clarity. You do not need hard float for the kernel as far as I am aware. As it is my understanding that floating point math in the kernel is "forbidden". However, many userspace tools, apps, and perhaps the userspace side of any kernel module may need hard float. On Thu, Sep

[beagleboard] Re: question from a total newbie...

The Beaglebone is a better choice than say, Raspberry Pi, since Linux is somewhat locked-down on the R Pi, which puts limits what you can do with it. On the Beaglebone, there are multiple variations of Linux that are supported, and you are free to compile your own kernel variations and load
