[ECOS] Problem with PowerPC simulator

[ECOS] Problem with PowerPC simulator

[Andrew Lunn]

Looking back in the archive i found a message that described my
problem. Please could someone tell me what the fix was.

The changes i made to the configuration are to change the HAL to
PowerPC, and enable the Minimal simulator. The processor is spinning
outside of the program....

Are you using the default configuration? 

Could you try building the library and tests with the default
configuration in a new build directory to see if it makes a difference
(this would ensure that settings from a previous configuration/build
are not being used).

I don't think it was ever resolved.

These addresses are wrong. _start should be at 0x4000 or so. Are you
sure you selected RAM startup, and didn't save and/or build on top of
an different configuration?

You cannot set it to RAM/ROM startup. Then you select the Minimal
simulator the Startup type option is not available. Thats only for the
Cogent PowerPC Evaluation board. Do i have an old version of the
config tool? I have version 1.1, Oct 29, 1998, 04:59:55 (someone was
buring the midnight oil!)

Im not quite sure what i did, but it now works, i get the PASS and EXIT lines

I think i changed back to the Cogent eval board setting, enabled
startup type ram, swapped back to the mininal simulator and rebuilt
everything. Maybe the startup type option needs moving from being a
subsection of Cognet to the same level as the Cognet and Minimal
simulator.

I think the problem is that you are using the same build directory for
Cogent and SIM. 

There are known dependency problems when changing config, so the
startup type may not have been reset properly when you started
building for SIM.

The workaround is to use separate build directories.

Cheers,
Jesper

That would not be quite right either. The startups available do depend
on the platform. Some platforms might only support RAM startup because
nobody has contributed a ROM startup yet. Other platforms might have
several different RAM startups, depending on which ROM monitor is
installed on the board - exactly what hardware is already initialized
and how may vary with the ROM monitor.

Instead it may be desirable to give a stronger visual indication of
the current platform and startup, to avoid confusion. This is
something we will bear in mind as the host-side software evolves.

Small correction: that was true at one point, but I believe all the
problems in this area were fixed or worked around before the 1.1
release. It should not be possible for any object files built for a
previous platform to affect the current build. If anybody can
reproduce the problem then please let me know how.

[ECOS] Problem with PowerPC Simulator

[Ramesh Naidu]

Hi All,

     I would like to develope one application using
 powerpc simulator and an application on linux and
 these two applications need to share a common
 data/memory. Is it possible for these two
applications
 talking to each other ? I have installed eCos on
Linux
 and both applications are running on same PC.

 Thanks in advance for u r suggestion.

 Ramesh Naidu

I don't know anything about the powerpc simulator....

Do you really need to use the powerpc simulator? Could you use the
synthetic target. eCos can then access the linux system calls and
setup access to an area of shared memory.
