S32G399 LLCE CAN bit timing issue

Yang_C — Mon, 03 Feb 2025 04:34:41 GMT

Hi,

I am using S32G3_VNP_GLDBOX3 to test CANFD 5Mbps, currently I am using the example project <Can_Llce_DS_Can2Can_S32G399A_M7> to modify the CANFD parameters.

When I tried to use Automatic Time Segment Calculation, there's an error popped out and I have no idea how to fix it.

So, can anyone from NXP share the CANFD bit timing parameters for 5Mbps?

Prescaler: ?
PROP_SEG: ?
PHASE_SEG1: ?
PHASE_SEG2: ?
SJW: ?
Transmission delay compensation offset: ?
Sampling Point: ?

My CAN_PE_CLK is 40MHz and I am working on the RTD.

Thanks

Hi @Yang_C,

Please can you share which versions are you using of LLCE and RTD.

Also please share the error you get when you try to use the Automatic Time Segment Calculation.

Thanks for your reply, recent I upgraded the IDE and so issue is resolved.
