[ECOS] Hello_eCos_World on iPAQ.

[ECOS] Hello_eCos_World on iPAQ.

[Victor Tarasov]

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:

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.

This is probably not what you really wanted to do.  You'll need to build
a separate configuration just for the 'hello' program, like this (in a
directory just for this):
  % mkdir /tmp/ipaq_ecos
  % cd /tmp/ipaq_ecos
  % ecosconfig new ipaq
  % ecosconfig tree
  % make

Then re-do your commands, but use /tmp/ipaq_ecos instead of /redboot/ecos-ram

Why do you want to recompile RedBoot?

Are you using the precompiled binaries available from 
http://sources.redhat.com/ecos/boards/ipaq.html ?

Once you know you've got something working, then you will probably find it
easier to rebuild and be sure there aren't any problems with e.g. your
tools etc.

It looks what you are describing is that you are using the build tree
configured with "ecosconfig new ipaq redboot" to build your applications.
This isn't right - the redboot template is used solely for building redboot
itself. Instead start with a new clean build tree and just use a default
configuration like:

ecosconfig new ipaq
ecosconfig tree
make

In fact then do:

make tests

which will build some test applications under install/tests/ which you can
try out on the board, which may help avoid any pilot error in building the
hello world example.

Do recompile RedBoot you must use the redboot template only. Make sure you
are using a new clean build tree when you build for a different template. 

I take it you are following the instructions in the RedBoot user's guide on
installing for the ipaq, of course.

Here is my 'hello':
#include <stdio.h>

int main(void)
{
  int i=23;
  printf("Hello, eCos world! %i\n",++i);
  ++i;
  return 0;
}


It seems that target console output do not pass through 'mangler'.
With the diagnostics output directed to the channel 0, the "$O..#" message, can be seen on the host.


#include <stdio.h>
#include <cyg/hal/hal_arch.h>           /* CYGNUM_HAL_STACK_SIZE_TYPICAL */
#include <cyg/hal/hal_if.h>

const char test_string[] = "$O5468697320697320612074657374206d657373616765210d0a#12";

int main(void)
{
  int i=23, cur;

  cur = CYGACC_CALL_IF_SET_CONSOLE_COMM(CYGNUM_CALL_IF_SET_COMM_ID_QUERY_CURRENT);
  CYGACC_CALL_IF_SET_CONSOLE_COMM(0);
  printf("%s\n",test_string);
  CYGACC_CALL_IF_SET_CONSOLE_COMM(cur);
  printf("%s\n",test_string);
  i++;
  return 0;
}
Target dies after the second printf.

Re: [ECOS] Hello_eCos_World on iPAQ.

[Gary Thomas]

How does this relate to your problem?  Can you send your 'hello' application (source)?

I tried these steps with our sample 'hello' program and there had no problems.

Tell us more about this, how you built it, which version of RedBoot you
are using etc.  AFAIK we do this all the time.

Thank you, now I can recompile redboot and seems it works properly on the iPAQ.


Another question:
I try to debug Hello application through the unique serial port of iPAQ.

Could you suggest any reason why writing to the /dev/ttydiag or to the /dev/haldiag kills the target

I think the issue is that anon CVS is not uptodate with respect to those
changes. I was going to do it last Friday, but timed out. Ditto Monday,
ditto today :-|. Tomorrow for sure.

Yes, there was a problem here.  This can be fixed by adding the command
  % ecosconfig add fileio
just before the 'ecosconfig tree' line.

There were no changes required to that file for the fixes I made.  Here's how
to build that file:
  % ecosconfig new ipaq redboot
  % ecosconfig import $ECOS_REPOSITORY/packages/hal/arm/sa11x0/ipaq/current/misc/redboot_Compaq.ecm
  % ecosconfig tree
  % make
The resulting file 'install/bin/redboot.bin' is what is distributed as "redboot.Compaq".
