Hi NXP's team,

i have some problems, I attach the source code below

*My Target

-CAN communication between S32K344 and CAN tool based https://community.nxp.com/t5/S32K-Knowledge-Base/Example-S32K344-FlexCAN-Ip-TX-RX-EnhanceRXFIFO-test-S32DS3-4/ta-p/1536225

*My hardware and Software

-S32K3x4EVB T172/orQ172 i'm not sure, S32DS 3.5, RTD 5.0.0

-I connected CANH, CANL, CAN_GND each togeter between Board and CAN Tool, but no date was be traced

*Can you check if they work on your side, and point out my mistakes?

Hi@Voledi

S32K3X4-T172 and S32K3X4-Q172 are different, and the CAN transceiver are different.

This demo is based on S32K3X4-Q172, and the transceiver used is TJA1153.

And this demo is based on S32 DS V3.4+ RTD 2.0.0, which is not compatible with the version you are using.

The attached is a routine based on S32K311, you can refer to it, the version is consistent with what you are currently using.

Hi@Voledi

According to the information in the picture, the transceiver here should be TJA1153, so there is no problem if you refer to this link, but this is based on S32 DS V3.4 + RTD 2.0.0.
