Is this site ARM OS dev friendly? It seems heavier on x86. Is there a better place for that platform? Just was curious.

Thanks

Of course there is a better place for that platform see here forums.arm.com/

But we can help if we are qualified to answer your question.

What is your question?

Nothing specific. In addition to x86, Ive been messing around with Raspberry Pi dev, and I really like ARM architecture (I come from old school 6502, which I am very comfortable with). x86 has alot of historic baggage it seems. Im hoping to see more ARM based PCs in the future.

Same here check out the ARM site specially their tools see here ARM Development Tools.

If you really love ARM you will love their IDE.

Also Check out Mentor Graphics Sourcery CodeBench

I really like ARM development too. I have a project(really part-time) on a Real-Time OS on a Cortex ARM. If you want to talk with me, I'll happy to exchange information with you.

I think if we start to talk about our project on the forum, maybe new ARM fan will joint us and we'll be able to add information about OS Dev for ARM.

I fund a really good start for a PI board if someone search for that,

I really like ARM architecture

Same here

There is infact an osdev article on this : http://wiki.osdev.org/ARM_RaspberryPi_Tutorial_C

Also, I'm absolutely enjoying this tutorial on arm assembly:

@Jvac would you happen to know where I could find out more about the versions. like ARMvX (like ARMv6) vs ARM Cortex-A8. I'm seeing a lot of different numbers and models and don't know how they relate.

It is true that the x86 family is dominating this forum. You can still discuss more abstract subjects here, like design decisions, as long as it is not too implementation-specific. And of course you are welcome to contribute ARM-specific information.

What kind of board did you use ? For me it's a beaglebone black.

@gideond

Most of the information is in the Arm Architecture Reference Manuel, but it's a really big file with a lot of information. The base is almost the same across the type of Arm processor.

How far have you gotten with the BBB? I bought one recently with the aims of porting my kernel to it,
but haven't done much other than reading the ARM System Developer's Guide and setting up a cross
compiler. Any tips before I dive in?

I only run my kernel on qemu for the moment, I use the BBB for a rocket competition in my university only. We use a linux embedded system for the moment. Maybe try to play with the linux operating system before flashing everything. We got some problem with a SD card, some time and I think it's about a electric short on our PCB. The OS on the memory chip copy itself on the SD card... So keep a backup of your SD card maybe it's will never append to you but we never know.

And a other advice I can give you respect the voltage limit of the pinout ! If it's say 3.3 volt it's really 3.3 volt (Duh!) at 5 volt the board stop working forever.....
