Are the read ID codes expected values?

Fortunately, your target has a lot of RAM and you can build the eCos
tests for RAM startup. Default startup type for your target is ROM
startup, so apply one import (see the below). Then try to upload and
run those tests via serial port using the built RedBoot (without FLASH
support) to continue a learing of eCos:

ecosconfig new <target>
cat >ram_startup.ecm<<EOF
cdl_component CYG_HAL_STARTUP {
    user_value RAM
};
EOF
ecosconfig import ram_startup.ecm
ecosconfig tree
make && make tests

If all passed smoothly, you find all tests under install/tests directory.

BTW, it exists a translation of the famous eCos book in Japan:
http://ecos.sourceware.org/docs.html


Hope that helps.
