Recovery from LIN error

ruihang_wu — Thu, 26 Aug 2021 19:37:07 GMT

How should we use the toolbox to handle errors during LIN communication?

For example, if the slave is supposed to respond to the header when the frame ID is 1, and it doesn't respond for whatever reason, I'm seeing that the master kind of gets stuck and never sends out anything else, even if I try to send another header on the master.

Using freemaster I can see that the lin1_State.isBusBusy and lin1_State.isRxBusy are both set to true. I'm wondering how I could reset the state and try to send out another header if the slave does not respond to a master header.

Yes I have followed the examples outlined in that tutorial. It doesn't really explain how to handle bus errors.
