I am facing some issue.I have described some steps below,please go through it and let me how can I fix this issue through Software?Is there any flag need to clear/set or anything?I am using TJA1028 LIN transreceiver for this.
- Monitor LIN bus and +5V
- Confirm the LIN communication is OK
- Perform a short-circuit between LIN and GND with a switch (relay or other) to short the LIN every second (not short – short – not short = 1second) during 10 second.
- Sometime, when the LIN short to GND is removed, the ECU wakes up and the LIN communication runs normally
- To be sure of the result, perform the test several time ( At least 6 times)
- You should observe an issue when the LIN short to GND is removed, you don’t recover the LIN communication
- To recover the LIN communication a HW reset is needed ( power off – power on the power supply)
