RE: [ECOS] Problem with running application on ARM Integrator

[<joeri_melis at agilent dot com>]

Is there an SDRAM module present?  When we were using gdb and redboot (over a year ago) we needed the SDRAM to be there.  If I recall correctly something in Redboot required it (we used ecos 28-03-2002 at that time).  Also if you have stuff on the pci bus that needs memory I think you will also need it.

We currently run an application on an arm7tdmi integrator without problems (ecos cvs 09-04-2004, gcc 3.3.2, ld 2.14) without redboot and configured in romram startup mode.

Regards, Joeri.

When I download the test I get a message that the application is loaded 
into 0x00040000 and doing a memory dump from there shows it to be present.

For Redboot, I chose the Integrator 7TDMI Redboot template and imported 
the redboot_ROMRAM.ecm file. Furthermore I disabled the ethernet support 
because I grew tired of waiting for it to finish booting. I had the same 
problem before I disabled this however.

For the test application I chose the Integrator 7TDMI default template 
and built it without any changes. I have also tried the minimal and the 
net template.

The repository is the 2.0 snapshot.
