S32K1 MBD CAN Message Lost after Disconnection from BusMaster

ykarata1 — Mon, 26 Oct 2020 09:50:27 GMT

Dear All,

I am using Model Based Design with S32K144 DEVKIT. I have implemented CAN communication. My communication block are typically categorized under two title.

1. 28 piece TX message

2. 1 piece RX message

When I build the model, code is embedded to the DEVKIT and I can see the all TX messages on my CAN line from BUSMASTER.

The problems that I have are:

When I disconnect via BUSMASTER and if that time is bigger than 1 sec as far as I measure, It never sends any of the TX messages. I need to reset again to see any CAN Signal.

My questions:

1. What may be the reason of this failure?

2. How can I solve that?

Any help will be appreciated.

Thanks.

NOTE: I could not share my model. If needed please let me know on e-mail.
