S32K3x4 FlexCAN example

Voledi — Wed, 11 Dec 2024 07:53:38 GMT

Hi, Sirs

I am trying to run the example you provided, to communicate between CAN board and CAN tool: Example S32K344 FlexCAN_Ip TX/RX/EnhanceRXFIFO test S32DS3.4 RTD200 - NXP Community
But I am getting the error below when configuring with Tool

Error: Mscr was not configured in Pin tool

Hi,

example was done in S32DS3.4 and RTD200, so you can have issues importing into S32DS3.5 and newer RTD if have any.
Anyway for an error you have, use MSCR number from pins used in PINs tool.
For example for some GPIO pin

BR, Petr

thanks for your reply,

i have solved the above error problem when setting Mscr=27 and Mscr=28 for PTA27 and PTA28

i am new to CAN, let me ask how PTC20 and PTC21 affect our CAN application ( Does it work without PTC20 21 ?) , what are the necessary and sufficient factors for a CAN communication to run
thanks

Hi,

those pins are connected to CAN transceiver's EN and /STB inputs on the EVB. Those are pulled up on the EVB to put CAN transceiver in active normal mode.
But if there is a need to change its mode etc, those pins will be needed as well.

BR, Petr

Hi,

I am using S32DS 3.6 AND RTD 5.0.0, to avoid conflict with project Example S32K344 FlexCAN_Ip TX/RX/EnhanceRXFIFO test S32DS3.4 RTD200 - NXP Community made on S32DS3.4 and RTD200

I did the following steps:
- Open FlexCAN_Ip_Example_S32K344 -> Config Tool -> Enabel PinTool->PTA27 PTA28 PTC20 -> SiuI2_Port setup ->Update code
- Replay old main.c with main.c of Example S32K344 FlexCAN_Ip TX/RX/EnhanceRXFIFO test S32DS3.4 RTD200 - NXP Community

The result I got the error below, I attached the project here, can you help

Hi,

check for name of pin config structure in Siul2_Port_Ip_Cfg.c and use parameters of Siul2_Port_Ip_Init accordingly.

It would be something like this...

Siul2_Port_Ip_Init(NUM_OF_CONFIGURED_PINS_PortContainer_0_BOARD_InitPeripherals, g_pin_mux_InitConfigArr_PortContainer_0_BOARD_InitPeripherals);

BR, Petr
