[ECOS] build redboot for AT91FR408

[Shaojie Wu]

Hi,

I have successfully installed redboot on 
Eb40 board and written some code for communicating 
between serial B and host PC, creating  multithreads, etc . 
However, we plan to run the redboot on a board(with AT91FR4087) 
which is designed by ourselves, It seems to do that, I need 
to modify the redboot. Since the eCos and redboot are 
new to me, I was wondering whether some one who did
that before could give me some recommendation regarding  
following questions:

1. what are  the  procedures  to modify  redboot  and 
run it on a custom-built board? (is there any documentation
talking about that?)

2.  is there a redboot version designed specificlly already for 
AT91FR408? , if there is, how to build the redboot?

3. without the support of redboot,  are there any other ways
to use eCos on a custom-built board? ( I found for most of 
the test programs generated by eCos do need the redboot 
to run)



Thans so much.
