WINCE 6.0 / AM3703 / Unknown exception - code dfff0123

Other Parts Discussed in Thread: AM3703

Hi,

We have an issue using WINCE 6 under AM3703.

When running a software we randomly have some error message : "Application ***.exe encountered a serious error and must be shutdown"

***..exe can be some navigation application (like Drive.exe for sygic but it does the same for another navigation programm), it can be our application (that uses .NET CF), or I already saw "servicesd.exe"

So I build an image including ''error report generator" componant and let running 5 platform during the week end with differents configuration. (One running only Sygic navigation / one running only another navigation software / one running our application / two running our application + navigation)

I got at least one dump file on each platform (2 dumpfile on 3 platform and 4 on 1).

When watching them with Windbg I see the same result :

^{(400002.3d20002): Unknown exception - code dfff0123 (!!! second chance !!!)}
^{Unable to load image srvkm_rev125.dll, Win32 error 0n2}
^{*** WARNING: Unable to verify timestamp for srvkm_rev125.dll}

^{srvkm_rev125+0x3c78:}

I have no idea where it can come from.

Is it an issue with srvkm_rev125.dll? or the dll appears because the symbols could not be loaded?

Any help or suggest are welcome.

Thanks,

Marc.

indeed seems to show that there is an issue with the srvkm_rev125.dll which is related to the PowerVR OpenGL libraries. There could be a bug in this library but fixing it would require heavy investigation and might be long to conduct considering the issue's reproduction rate.

Thanks for answer,

I forgot to update my post, but you are right, I removed PowerVR component from the OS and it seems to works fine now;

Please note that AM3703 does not have SGX (3D graphics core). PowerVR should only be enabled when you have SGX core enabled in the silicon. Hence disabling PowerVR is the correct solution for you.
