Dear QiangHuang:

First, Thank you for your patience. :-)

I installed this epk by admistration tool, and choosen EPXA1 template
to build eCos lib. Then I maked simple test program to link eCos lib, and
got a srec file. Last, I use terminal software to load this srec file by
following
command. Are all steps correct ? The executed result seems wrong.

The eCos version I use is 2.0.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^  <----- very strange ? what is this ?

The attached is the simple test program from book's CD. Thank you.
