Just getting started on a new project consisting of a PowerPC 405 processor on a custom board (i.e. no BSP available, we'll have to build one).
Operating system is Micrium MicroC/OS-II; development environment is Eclipse on Windows XP; language is C.
Eclipse on Windows seems most happy with MinGW as a compatibility layer with GCC; it seems less happy with Cygwin although I would imagine it can be made to work. In any case current plans are to use MinGW if we can.
First thing I'll need is a PPC-405 cross compiler port of GCC, that runs under MinGW. Micrium appears not to have a PPC port of GCC at all, in any flavor or for any platform... they told me to contact Corelis and buy their CodeSymphony. I did that (contacted them, didn't buy CS yet) and the information I have is that CodeSymphony is designed for use with the Corelis JTAG controllers only, and to the best of my knowledge and belief there are no plans to implement JTAG in general or Corelis JTAG controllers in particular, on this board.
So, first of all, does anyone know of an available PowerPC GCC port for MinGW? If not, can someone point me in the direction of some literature that I can use to teach myself how to build it?
While all of this is going on, I'll have to investigate this project further and see what plans have been made for board bring-up and BSP (currently I'm only involved in a relatively small part of the software on this board, not involved in the hardware at all).
Thanks...
