[ECOS] [Fwd: Re: [ECOS] IDT MIPS support]
Tue Aug 8 09:49:00 GMT 2000
I'd like to clarify the following:
1. What does it mean -
"the NEC VR4300 is an implementation of
the 64-bit R4000 architecture (although the eCos port only uses it in
If I understand correctly, the available port is done only for the 32-bit
mode of the MIPS CPU.
If we need the 64-bit implementation in the eCos, compiler and debugger -
what should we do ???
We are very new to the eCos and free s/w - every piece of information will
Thank you very much,
