System Error on phone; runs fine in emulator

[dracula78]

My application runs perfectly in the emulator, but when installing it on the device (Nokia N91) it only gives a "System Error" when starting the application.

An app-TRK session showed that the execution didn't get far:
The initial breakpoint is here:

GLDEF_C TInt E32Main() {
    return EikStart::RunApplication( NewApplication );
}

And NewApplication calls this function in e32base.inl:

inline TAny* CBase::operator new(TUint aSize) __NO_THROW {
    return User::AllocZ(aSize);
}

The value of aSize is 0, and the System Error occurs there.

Two questions:
- What's happening here; why does it differ with the emulator run...?
- How can I get the phone to display error code in case of a panic or system error?

I'd read about the ErrRd file, but it doesn't seem to work on my N91 test-device. With Nokia PC Suite I can see a C: drive (Phone memory) with only a Data directory; it has an E:\RESOURCE directory though, which is on the Memory card. After installation of the ErrRd.sisx I don't see an ErrRd file appear anywhere.

However, the error code thing would be helpful for future debugging... Do you happen to recognize the "System Error"-on-startup problem?

I think that you need to read a bit more. Try this: http://wiki.forum.nokia.com/index.ph...ded_panic_code

By installing the sis package the ErrRd file was probably created though that does not mean that it is in any way visible (nor need it be).

Once extended panic information enabled the "System error" message would probably be followed by "-1" (KErrNotFound) indicating some problem with the registration file or some missing component (dll, resource ...) .

[dracula78]

Yes, that was also displayed in the screenshot. However, after installing the ErrRd.sisx (which went fine), the dialog still shows "System Error". Sorry for not having mentioned that clearly in my previous post...

[ltomuta]

Interesting ... can you please post the firmware version of your device ?

If i am not wrong, you are launching a Ecom from a Stub exe. I face the same problem if my ECOM is not correctly installed / registered. check to ensure that it is registered in ECOM plugin

skumar_rao: Thanks for the reply. Can you explain a bit more about that? My application is an exe (not a dll), but what exactly is an ECOM? How do you register it?

I've tried both on-device debugging and installing the generated .sisx, both with the same results: "System Error" before the application is even displayed.

Itomuta: Tomorrow I'll post the firmware version of the device, if I can figure out how ;)

[ltomuta]

If you do not know what ECom is that it is likely that you do not use it. As for what ECom is there is enough documentation in SDKs and Forum Nokia ;)

For finding out the firmware version dial the following code on your phone.

ECOM - > EPOC-COM
They are used to support Plugin Architecture. For more information try going through this http://www.forum.nokia.com/info/sw.n..._0_en.zip.html

It has all the Docs about ECOM

My N91 firmware version:

V1.00.028.13
29-03-06
RM-43

Somehow, the "System Error" now no longer even appears; instead, when launching my installed application the screen flashes once and returns to the app. menu. As a test, I single-stepped through HelloWorld with App TRK, installed and ran it, all with success.

Could it be that when the wrong capabilites are selected (or missing) in the .mmp, this behaviour occurs? I have no idea where to look for the cause of the crash, because none of my code actually gets executed yet.

Hi,

Did you tried uninstall the application and deleting all its necessary files and install it again...?

Peter

[dracula78]

Yup, I removed the application and re-installed it several times, without result.

You mention "all its necessary files"... I assumed that all resources are included in this .sisx file I'm installing, is that correct? If I'm wrong, where do I put the various resources used by my app (.wav, .bmp, .rsc, ...), and how?

Search for this pdf file in forum nokia "S60_Platform_Symbian_Platform_Security_FAQ_v2_0_en" this is good pdf talking abt various resources used by your application and its path etc.

This is very Simple Error to solve.

Please install new EPOC in your system. compile your code make sis file.

Your problem solved. I have faced same problem. i done clean EPOC build it is working fine.
