LIN Stack CRC

Hi,

Just a quick question. Based on the LIN stack example, we imported another LDF-File (Version 2.1) generated everything., compiled, flashed. Microcontroller is sending, but on our PC-program for simulating the LIN-Slave we had to change the CRC from enhanced (LIN 2.0) to classic CRC (LIN 1.3). So that communication in both directions is working.

We expected : LIN enhanced CRC (because LDF-File is Version 2.1) from NXP microcontroller.

So can we change the used CRC in the NXP S32DS linstack module?

Thanks in advance!

Hi @nxp_user001123,

Can you please specify the S32K part number, SDK/RTD version and the LIN Stack version?

Thank you,

BR, Daniel

Hi Daniel,

Yes sure:

RTD : 5_0

LIN Stack : 2_0_5

We are using the eval board S32K3X4EVB-T172

Hi @nxp_user001123,

Can you share the LDF?

What frame types do you send?
