S32K344 CAN demo could not send message succeed on EVB257

[KILLERzheng]

I configured the MCAL in EB tresos, and generate the code. In S32DS IDE, I import RTD modules and move the genrated code(from EB) to the project. Build the project succeed, but it could not send CAN message out, even on PAT7 port ( PT275 on EVB), I could not get any waveform. The project as bellow, could you please help me and figure out where the problems is?

Thanks!

Hi@KILLERzheng

please refer to this answer.

It is not same situation as that one. I know TJA1153 should be initialized before send message, and I have done(may be not correctly). But even if I have not initalized the TJA1153, the mcu TX pin should send message out and I can get the waveform by oscilloscope. However, I can not test any waveform.

Hi@KILLERzheng

There is a example code for your reference.

Name:

"Can_example_S32K344"

Address:

SW32K3_RTD_4.4_1.0.0\eclipse\plugins\Can_TS_T40D34M10I0R0\examples\EBT

BR!

I know it.

But this demo just work as loopback mode. When I change the configration and make it in normal mode, I still can not get the waveform from the TP275(test point, CAN0_TX of MCU).

Could you please help me and figure the error of my own project that I posted before? Thanks

Hi@KILLERzheng

I tested your code, but it keeps going into hard faults, it seems that this is not a configuration error.

Platform_Init(NULL_PTR);

I found the error place. Threr is no configuration error, but the main function is wrong to init the mcu clock
