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

[joeri_melis]

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.

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.

As far as I know no specific magic was used to turn on redboot at that 
time.  I do know that we only got gdb working reliably over the serial 
interface with it (not over net or multi-ice).  But I wasn't the 
person who played with redboot at that time so I can't say for sure 
the configuration wasn't altered.

Comes out of my head so don't shoot me if I forgot some steps.
You need to change CYG_HAL_STARTUP from RAM to ROMRAM (or ROM if you 
want to run from flash) in your ecos.ecc.  The executable you make 
has to be transformed in srec format using objcopy, and then you can 
load it with the ARM bootloader.

But if you are not sure about your application or ecos setup I wouldn't
recommend starting with this as you have no debugging support and you 
are thus responsible yourself for getting anything out of the system.
Do the diagnostic leds give any clue about where it stops working?

Joeri.

  Have you looked at the listing file of your image? What is at 0x04000044?

This seems extremely odd to me.  I just built a test for the integrator
and it loaded at 0x00040000.

It sure looks like it.  How did you configure your eCos kernel?

I have installed Redboot using the Arm Flash Utility and it boots fine 
and I am able to connect to it using GDB.
Downloading the application with Insight also goes well, but when it has 
finished I get

Program received signal SIGTRAP, Trace/breakpoint trap.
0x04000044 in ?? ()

I have tried to set a breakpoint at hal_hardware_init in 
integrator_misc.c - the earliest place I could find - but I still get a 
SIGTRAP.

I get the exact same message no matter which test example I try. Could 
it possibly be Redboot that tries to execute the application from the 
wrong address?

  We have RedBoot/eCos running fine on our board (http://armoid.com). What 
errors are you getting? Have you been able to debug your apps?

I presume that you have RedBoot installed and running?

Have you tried the examples at http://www.mlbassoc.com/examples ?

[ECOS] Problem with running application on ARM Integrator

[Henrik Mau]

I have an ARM Integrator development board with an ARM7TDMI processor on.
I am trying to get an application to run under eCos on it but have 
failed so far.

Is there someone that have succesfully run an application on the ARM 
Integrator with an ARM7TDMI processor on it who can give me some 
guidelines as to how to get a simple application to run on it?
