[ECOS] Hello Example

[ECOS] Hello Example

[Ron Avisa]

I have setup the ecos config for a "default" cirrus ARM 7xxx board with RAM 
startup
and 7212 cpu settings. I have flashed my board with the cymon_ROM bootloader.
I have built the ecos kernel and tests and have been able to download and 
run them
successfully.
The next step then was to put together a simple app and try downloading that.
I modified ...\eCos\examples\makefile to have a working dir pointing to my 
ecos-work_install
directory and I set XCC up for ARM 7212
and did a "make". This seems to work fine producing a 1.2M image.
However when I attempt to download this via GDB/insight I get

"error: invalid download offset message"

Any help is appreciated,

Thanks

Ron

Good, so there's nothing intrinsically wrong.

If you open the console first, there should be some output. What is it?

using gdb/insight I am connecting on serial port 0 successfully at 38400.
I have the download at connect option disabled.
I then select FILE->OPEN /c/Program Files/Red Hat/eCos/examples/hello.exe
  I start a console window, connect and see the following:
--------------

0xe0006338 in ??()

(gdb) LOAD

Error: invalid download offset: /files/redhat/examples/hello.exe

--------------

Any thoughts?

Oh hold on. I think this might be something to do with spaces in filenames.
What version of GDB is this? Perhaps try the latest GDB snapshot:
http://sources.redhat.com/gdb (or http://sources.redhat.com/insight if you
want the GUI).

Re: [ECOS] Hello Example solution

[Ron Avisa]

Many thanks!
I moved all the example files to

         /c/work/examples/

and tried running them from there and they work perfectly.
I'll go ahead and get the latest GDB snapshots as well.
Thanks again,

Ron

Yeah, it would be useful if you tried it with a recent GDB so that I can
arrange to get it fixed if the problem is still there.
