Hi Jonathan,

Thanks for your help.Now Redboot is working.

    I followed the example on provided in the book "Embedded software
development with eCos", by Anthony J.Massa, P.300

But when I tried to load file using Redboot, I got the following error

Copyright (C) 2000, 2001, 2002, Red Hat, Inc.

RAM: 0x00000000-0x02000000, 0x00024628-0x02000000 available
RedBoot> load -v -m ymodem
*** Abort! Attempt to load S-record to address: 0x00020000, which is not in
xyzModem - CRC mode, 1(SOH)/1(STX)/0(CAN) packets, 3 retries

what does cause this problem?

Your RedBoot is using quite a bit of RAM, and the RAM app is built to use an address within it. You need to change the RAM base address in the mlt files.
