We have a PowerPC 440 EP (from a AMCC Yosemite evaluation kit) and we are in the process of evaluating OSes for it. The industrial strength ones (like vxWorks) are too much feature-wise and money-wise, so we're hoping to try out uC/OS-II.
Why not using a feature-rich, money-efficient solution like Linux? One of the big advantages is that you get a running system completely for free and out of the box...
The software has to eventually undergo certification, and uC/OS-II should be a smaller codebase to certify than Linux.
- Can the porting layer of uC/OS-II use some of the u-boot functions for PCI
and ethernet access?
It can, if you use the GPL2 based "Open Source Licensing" model of uC/OS-II.
- Are there any existing instructions on how to build (or create a makefile)
uC/OS-II using the compilers supplied by the ELDK? I keep getting a failure to "find entry symbol _start", even if I include the gcc libraries, crtbegin.o, etc.
Well, that's starting to be off topic here...
