Excellent! It's not stripped elf.

I see nothinig illegal the above: .text, .*data, .bss do seat silent in
the RAM its total size about 40K.

What's a nice board! IMHO, it's very suitable for eCos. You have ~1M of
a volatile memory.

Graham, let's resume what you've got:
1) You have arm-eabi GNU toolchain with it you are able to build eCos
2) You have a nice bootstrap environment with GDB support -- RedBoot.
3) You are able using X-modem protocol and minicom to upload the images
into RAM. IMHO, if you can to load a test image in a few hundreds of
Kb into the RAM, your GDB must do it too.
Before to start debug GDB protocol, dance with packet's sizes, etc. My
the first guess: you misconfigured eCos build. I do not know how you
configured eCos build. I do not know what you check/uncheck using eCos
So, can you reproduce the below just in Linux bash?
i. Build a minimal eCos stuff as
echo $ECOS_REPOSITORY >> report.txt
echo $PATH >> report.txt
ecosconfig new stm3210e minimal
make -s -C hal/common/current tests
ls -R install/tests >> report.txt
Note: attach the report.txt then.
ii. Leave minicom if it runs!
lsof /dev/ttyS0 ;# you must see no output
iii. Reset the board and invoke arm-eabi-gdb as
arm-eabi-gdb -q -nx install/tests/hal/common/current/tests/basic
Now on GDB prompt type a line by a line (see the below)
(gdb) set logging on
(gdb) set remotebaud 38400
(gdb) target remote /dev/ttyS0
Here you can to see that board connected, if gdb wait here, reset the
board and try `target' command again.
I very hope that will be done. If it will, continue:
(gdb) b cyg_test_init
(gdb) b cyg_test_exit
Please, repeat the above lab1 exactly! And the report about the results:
attach report.txt, gdb.txt. The files should be in that /tmp/lab1
