[U-Boot-Users] OR1200 (OpenRISC) Support?
Hi Jerimiah,
My question is this--has anyone worked on getting the necessary software put together for u-Boot to support this particular processor architecture?
Not that I am aware of.
If it isn't currently supported are there any tutorials that I could read through concerning creating the necessary additions and modules to support the hardware?
I've always wanted to scratch my itch for the OR1K and bring it up on an Altera Cyclone. I'd be interested in helping out (if I can find some time).
If you're familiar with the Altera Nios, you might find the nios2 tree helpful as a template.
Regards, --Scott

I have a project I'm working on that I think u-Boot would be perfect for. The core processor architecture is the OpenCores OR1200 RISC platform, however, and I see it doesn't appear to be part of the standard release of u-boot. My question is this--has anyone worked on getting the necessary software put together for u-Boot to support this particular processor architecture? It appeared to me that the only place it's mentioned on the Denx site is a brief example of the Custodian system.<br>
That's just a coincidence - we chose an non-existent (and from our point of view also somewhat unlikely) architecture for the example.
I am not aware of any existing code or porting activities.
But at least you already know what the name of the respective custodian repository would be :-)
Best regards,
Wolfgang Denk

Actually, that's not quite true.
Having played with the or1k simulator a long time ago, I made myself believe in the subversive idea that mentioning it in our documentation could possibly lead some attention to it. I'd still love to see a system that can be studied at (practically speaking) every level of the design...
I did not dare dream of that actually coming true though ;)
Cheers Detlev
Well, I'm hoping to start work on creating CPU support for the OR1200 as soon as possible, so maybe I can help fulfill that dream of yours Detlev. ;)
I'm new to the world of U-boot, so I'll probably be asking questions along the way.
