Hi,
It seems that I am not so intelligent to run alone my first RedBoot
application on iPAQ.
Can you help me, please?

Package installation was made by:
>ecosconfig new ipaq redboot
>ecosconfig import redboot_RAM.ecm
>ecosconfig resolve
>ecosconfig tree
>make

Hello_eCos was compiled with:
>arm-elf-gcc -mcpu=strongarm                      -c -o hello.o -g -Wall
-I/redboot/ecos-ram/install/include -ffunction-sections -fdata-sections
hello.c
>arm-elf-gcc -mcpu=strongarm                      -nostartfiles
-L/redboot/ecos-ram/install/lib -Wl,--gc-sections -o hello hello.o
-Ttarget.ld -nostdlib /redboot/ecos-ram/install/lib/version.o

Then GDB:
>arm-elf-gdb  -nw  hello

(gdb) set remotebaud 38400

Continuing.

Nothing happens after.

PS: How can I recompile RedBoot for iPAQ?
"RedBoot" template with the imported configuration
$ECOS_REPOSITORY/packages/hal/arm/sa11x0/ipaq/current/misc/redboot_Compaq.ecm
(also redboot_rom.ecm)
gives the binaries that are not working on the iPAQ.
The templates "all", "default" and "stubs" give the error during
compilation.
