Hello everyone,
I have been trying to send two bytes of response with 3rd byte as a checksum from my microcontroller(S9KEAZN64AMLC) to the CanOe tool. it is showing a Timeout error for only 2 bytes of the response for every consecutive frame ( if send consecutively one is received and one gives an error it continuously), the same code same system, and the same configuration running flawlessly for 4 bytes, and 8 bytes also.
Configuration is Baud rate is configured for 19200
every transmission and reception done in MCU is from ISR. using Read data register full Interrupt for reception (request )Interrupt and Transmission data register empty for Transmission (response)
below is a screenshot attached for the CAN tool receiving data.
below is the attached LIN bus signal from the logic analyzer.
We tried to fix this issue by increasing jitter in LDF, and instead of configuring Transmission data register empty configuring for Transmission complete Interrrupt still same issue .
