From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Raspberry pi works fine with linux, cutiePi also. my iomega nas is an arm board running debian...i don't see the issue

The issue with Arm is they aren't all one board/chip, you have ARM based design licenced from them and they are built to meet the criteria of what the customer requires. i.e. for my iomega NAS there isn't firmware boot, you just have to generate an empty section of 00s on the first 32bytes of the drive so the board knows that is the drive to load the kernel from (no grub no uboot) and the board is set to do the rest from the next partition.

Booting isn't the only problem with ARM. Instead of saving information about builtin devices on the board and exposing it via ACPI, board manufacturers create a devicetree and ship it with the kernel. This means that if you want to run your own kernel you need to build your own devicetree
But all x86 instructions are the same right, thus why it doesnt matter what era your chip is from or what manufacturer, arm can be very different

Thanks for the info, I appreciate the reply
Theese devices support linux out of the box. Try installing a proper linux distro on your phone and good luck finding a graphics driver that is not sotware rendering
As did microsofts arm device support windows, which is the point zi was replying to with skullgiver. of course windows works if the arm version was built for the hardware it runs on.
