Re: [openrisc] problems on porting uClinux to my own cpu!

["Neal" <ee9721@etang.com>]

My cpu is instruction compatible with ARM cpu, so I'm lucky to use the existing 
arm-elf-gcc+binutils tools.  The remaining task for me is to adapt the source code 
to my cpu.It seems that there is no reference book on this topic.I'm eager for your 
advice.

Thanks for your concern!

Best regards

William Neal

uclinux.org is much more appropriate place for this topic.

But in any case you will need a gcc+binutils port, which is much more complex 
than uclinux+uclibc port.
