FlexCAN messaging on KEAZ64 Board

[GarrettMJ]

I am wondering if there is a way to get FlexCAN working on the a KEAZ64 board as I am trying to port over some J1939 CAN code that is setup for a FlexCAN module to a KEAZ board. I am unfortunately not able to get this to work and can't find anything saying this is even possible. Any advice would be extremely helpful.

Hello @GarrettMJ,

Unfortunately, there is not an example about the KEAZ64 board and compatibility with J1939. Nevertheless, it could be useful to take a look to the following information:

• CAN 2.0 vs SAE J1939 - NXP Community
• S32 KEAZ-SDK & PEX, MSCAN Missing --Help! - NXP Community
• KEA128 Sub-Family Reference Manual. Chapter 32 Freescale's Scalable Controller Area Network (MSCAN).
• KEA General Purpose Evaluation Board | NXP Semiconductors, you could download the MSCAN driver here which could be helpful.

Best regards, Raul.

Hi Raul, thank you for the support. Is there any sample code for MSCAN that is able to show it sending and receiving multiple CAN messages? I can only find the Test_Case code for the driver that allows for either 1 message to be sent or 1 message to be received. Any sample code to polling for messages and the sending of multiple messages would be highly appreciated.

Hello @GarrettMJ,

Sadly, the only example of KEA's MSCAN is the Test_Case you mention. Nonetheless, might be helpful to check the following information:

• Using MSCAN on KE16Z MCU
• regarding CAN Tx and Rx in KEA128 - NXP Community
• Questions about sending and receiving multiple CAN... - NXP Community
• AN2283/D: Motorola Scalable Controller Area Network (MSCAN) Interrupts

Sorry for any inconvenient this may cause you.

Best regards, Raul.
