LLCE LIN interrupt

pmboat — Wed, 27 Aug 2025 02:10:38 GMT

S32G3 has 4 LLCE lin channels, I configured Lin1 channel as slave and Lin0, 2, 3 as master.

I need to verify the slave's receive response function.

I have configured and enabled Lin1's interrupt in EB, the callback function is Lin_CmdFromLlceIsr, when I send a Lin message to Lin1, Lin1 does not enter the interrupt response, only when I enable Lin2 interrupt instead, it can enter the interrupt, Lin1 will give a response at this time, why is this happening?

1. Seems you are working with LLCE LIN? is it right?

2. Which version RTD/LLCE FW you are working with?

Hello, @pmboat

Thanks for your reply.

By default, The Lin LLCE firmware is running on the internal CORE 2, so that the LLCE_INT2 is used for LLCE LIN cases.
