New RTEMS user..

[Patrick O'Banion (TMMC)]

Hello,

So I built my first set of "Build Tools" for the sparc erc32 as suggested in the rtems help docs.  I was able to get the gdb SIS working with a modified "Hello World" example. (see attached)

Now I want to start working towards my goal of using rtems on a development board.  Here is where the noob questions comes in...
1. If I create a second set of build tools for an ARM processor, what is the best way to define the directory structure for it?
I currently have these defined for the sparc erc32...

~/development/rtems/5
~/development/rtems/src/kernel
~/development/rtems/src/kernel/erc32
~/development/rtems/src/kernel/rtems
~/development/rtems/src/rtems-source-builder
Etc..

If I build a new set of build tools, can they share these directories?  I expect I will get a second set of "arm" build tools in my "~/development/rtems/5/bin" directory.  I can see how in the src/kernel I can create a new build directory.  For example "~/development/rtems/src/kernel/arm" and recompile rtems for an arm processor there without disturbing the erc32 build.  But what do you typically do for the tools?  I could archive them in a new directory or just change the dir name to something erc32 specific...  There are probably numerous ways to handle it, I was just wondering if there is a standard method most rtems users prefer.

2. My final targets are an adafruit M4 Metro (https://learn.adafruit.com/adafruit-metro-m4-express-featuring-atsamd51/overview) and an adafruit Trinket Pro (https://www.adafruit.com/product/2000).  Could someone maybe help suggest the closest BSP for these boards?  I don't mind attempting to build/modify the BSPs.  I think with some help from the rtems community and google I could do it.

This is my first stab at RTEMS so anything anyone can offer would probably help.  I do have some limited experience with RTEMS from one of my previous jobs (2004-2006).

Thanks for your help.

Regards,
Pat
