9.13.3 MOST XML Catalog<br />
185<br />
The demo replays a logging file in offline mode to show the disassembly capabilities<br />
of the Trace window. Therefore the configuration imports two sample XML Function<br />
Catalogs. No real hardware is required for running the demo.<br />
9.14 Known Problems & Trouble Shooting<br />
9.14.1 Measurement Windows frequently disabled<br />
In spite of a moderate bus load on the used CAN or MOST channels, the measurement<br />
windows frequently show a notification ‘disabled’ in the title bars.<br />
Please check:<br />
• Are the COM port settings in the windows control panel correct?<br />
They must be 115.2 kBaud, 8 Bit, no parity, 1 Stop Bit, Hardware flow control<br />
9.14.2 <strong>CANoe</strong> doesn’t receive any MOST Frames<br />
Please check at first:<br />
• Does the Optolyzer have light&lock<br />
• Are there MOST frames to receive<br />
• Is the Optolyzer addressed (either in Spy Mode, or with correct node or group<br />
address)<br />
The mode is configured either in the MOST hardware configuration dialog or in<br />
a CAPL program.<br />
• In spy mode: Is the HW Filter switched off?<br />
• Is there a message ‘MOST x: Obsolete Firmware? (Version >2.41c required)’ in<br />
the write window?<br />
This indicates that the time synchronization couldn’t startup. An obsolete firmware<br />
version of the Optolyzer box may be the reason.<br />
If sending MOST frames and receiving Tx acknowledgements works well, but still no<br />
MOST frames are received, the firmware of the Optolyzer box may be obsolete. For<br />
usage of <strong>CANoe</strong> .MOST at least version 2.50 of the firmware is needed.<br />
9.14.3 <strong>CANoe</strong> doesn’t receive some MOST Frames<br />
When running an Optolyzer box in node mode (Master, Slave), only messages sent<br />
to the node’s address will be received. Furthermore, acknowledged frames will be<br />
processed, only. Not acknowledged frames can solely be detected in Spy mode.<br />
While driving the Optolyzer box with high load (simultaneous transmission and reception<br />
of multiple messages), the receiver (Optolyzer) may need several send retries<br />
before it acknowledges a reception to the sender. Adjust the number of retries at<br />
sender site.<br />
