Hello Keneth,

sorry for my long absence.
I'm interested in the patched DLL. I've sent a mail to info@peak-system.com to leave my mail-address.

Thanks for all your effort!

Hello Keneth,

here is my "minimalistic" example: http://pastebin.com/1R4YHdep
Unfortunately it's not really short and looks ugly with all those magic numbers flying around.
But now I used pure C++ without the qt library and the code doesn't produce any threads.

I just realised that this code does ...

Hello Keneth,

I'm not really using threads. I am using the Qt-GUI-framework which produces some threads but all the xcp functions get called inside one thread. But I will write a minimalistic example without using Qt. Thanks for the tip!

In the last minutes it got even weirder. I temporarily ...

Hello Keneth,

For some reason I used the wrong byte order - I set the TXCPProtocolLayerConfig::MotorolaFormat to true instead of false.
After fixing that XCP_DequeuePacket doesn't return 0x800 anymore but the program crashes due to a segmentation fault in the call of XCP_DequeuePacket.
I have no ...

Hello Keneth,

Thanks for your reply!
I double rechecked the return code of XCP_DequeuePacket and it really gives me 0x800.
When would the XCP_ERR_INSUFFICIENT_BUFFER error normally occur?

Thanks for your help!

Hello,

After connecting (successfully) to an ECU, dynamically allocating one dto-entry in one dto in one daq-list and calling XCP_StartStopDAQList, I call XCP_DequeuePacket and get XCP_ERR_INSUFFICIENT_BUFFER as result.

The call of XCP_DequeuePacket looks like that:

WORD packet_buffer_length ...

Hello,

thanks a lot! The ECU uses dedicated DTOs and I did not know about that. I called CCP_GetDAQListSize with the standard CAN-Id, which was obviously wrong. Now - using the daqlist-specific DTO - it works.

Do you know where I can read more about those dedicated/non-dedicated DTOs? I haven't ...

Thanks a lot for your fast response!

Hello lslahrs_,

About the Event:
Registering an event through CAN_SetValue will signalizes that CAN data has arrived. This signal is also received internally by the CCP API in order to work out CAN Frames (convert it to a CCP Frame). It is possible that you ...
