- Subject: Re: [ECOS] Download a RedBoot on AT91
I have a relatively current CVS tree for building eCos
code now for the EB40 target. I'm also in the same
boat as far as the EB55. Just received mine yesterday
in the mail and want to get redboot/tests going on it.
Can I expect the patches to work with the current CVS
or do I need a certain CVS date to apply the patches
to first?
If I understand correctly:
1) Apply AT49xxxx flash patch
2) Apply EB40A target patch
This splits apart the EB40, EB40A and AT91 code ???
3) Make a EB55 target simular to EB40 and EB40A
targets by modifying the appropriate directories and
files for the EB55, ie ecos.db the *mlt *ldi files etc.
Is this the gist of it?
I guess the next thing to do is read the porting guide
and just dive into it.

Just copy those,
