In general it seems Red Hat prefers little-endian. Past discussions on this 
list have indicated that not everything is guaranteed to work in big-endian 
mode.

Have you tried a simple test program?

int main(void) {
unsigned int u;
unsigned char *p;

u = 0x12345678u;
p = (unsigned char *) &u;
printf("%2X:%2X:%2X:%2X\n",*p,*(p+1),*(p+2),*(p+3));
}

I don't know exact answers to your second question, but if you did an 
"ecosconfig new assabet redboot" and then "ecosconfig tree" then "make" you 
would wind up with the RedBoot debugger/loader for the Assabet board. 
Exactly how to load this onto the target board varies with hardware. I'm 
using ARM, not SA, so I can't advise much there :) THe closest document I 
can see is
