Hi,
Two humble apologies in advance:
1) sorry for spamming y'all that didn't hit the 'delete' button or spam filter already and have wasted valuable seconds reading this
2) sorry if this is completely the wrong place for this email --- please let me know where I should have gone instead
However, given the following (and other similar blurbs I found on the Wiki):
Potential Ports
We are always interested in adding ports to other CPU families supported by the GNU tools. If you are interested in working on a port or are ready to submit one, contact us.
- Atmel AVR
- Xtensa
- Motorola MCore
- Texas Instruments C6x
- ARC
- ...
This is to let "us" from "contact us" know that I am interested in porting rtmems to Motorola MCore, or to be more specific, to my s8g001 processor (and s8g1eb platform/board), which is 99.999% compatible with MCore (i.e. minus some MCore bugs).
I'm going to go ahead with this starting next month, with or without help, and any comments/suggestions at this point would be welcome (especially the "don't bother, it's already been done" kind:)
I'm primarily a hardware/processor/ASIC/SoC designer, but I do know my way around software (C/C++/assembly/etc), although my OS/porting experience is limited (for now).
I've worked on/with MCore processors for many many years, and I'm intimately familiar with the hardware and ISA, having system-designed with, and (re-)developed/implemented several MCore variants (SM210/M210S/M310S/C306/C310/C312/CS320/etc and my own compatible s8g001/011/012/021 cores) in various 0.35u to 45nm processes and FPGA.
At this point, I've got my MCore compatible processor(s) coded, synthesized and running on my FPGA board. I've cross-compiled GCC/binutils with Newlib, to the point where I'm able to compile simple C-code programs and have those execute on my processor/board.
I've got a big/long technology roadmap that includes faster cores, multi-core platforms and DSP-extensions, however, my immediate/next step is to have 'something' OS-ish ported to my core/board such that it can boot up to a linux-ish command-line prompt. I'm assuming that rtmems will suit, and that it (porting) can be done for a system that includes just one CPU, some RAM, ROM, and one or two serial ports for I/O (text display and keyboard?). I'm happy to add other hardware as needed (eg MMU, graphics, etc). The ultimatre goal is to have all the bells and whistles (full blown desktop/server linux, openCL, etc) on an MCore based many-core platform, but one has to start somewehere. I'm guessing just porting/booting rtmems will be difficult enough to keep me entertained for a while...
So, there! Comments anyone...?
Thanks,
Michiel (sgtas at mail dot com).
