RE: [ECOS] loading programs to RAM via RedBoot (using minicom on Linux)

I figured it out.  The person who installed my Linux box
forgot to include the lrzsz-XX.i386.rpm!!!  Sorry about the
post, it was pilot error on my part.  Funny that minicom would
not complain that /usr/bin/sx did not exist.

Things are working great now.

If you don't try to do the upload, what speed do the "C"s come out? If it's
faster than one every two seconds, you need to improve your delay_us.
Otherwise, you might have to just type faster :-).
 
You could up the values in the #defines at the top of xyzModem.c. Really
those should be CDL options anyway.

[ECOS] loading programs to RAM via RedBoot (using minicom on Linux)

[Warren Jasper]

I'm not having much luck using the load command
with minicom via a serial connection to RedBoot.
Perhaps someone can tell me what I am doing wrong or
did not configure correctly.

1. RedBoot> load -r -v -b 0x100000 -m xmodem
CTRL-A Z -> S -> xmodem -> select file to upload 
I then see:

CCCCC..........Can't load '<null>':Timed out
RedBoot>

When I dumped the memory on the ARM at 0x100000, nothing came
across.

Any help or suggestions would be appreciated.
