S32K312 flexcan example not running on Power reset

Adrish — Tue, 06 Feb 2024 09:49:42 GMT

We want to send CAN messages periodically. I am using the FlexCAN example for RTD 3.0.0. Additionally, i have configured a PIT timer so that I call the Flexcan_send periodically.

The code is building and running fine, but when I do a power reset on the board, the messages only come for a few seconds and then the code gets hanged.

I am using the S32K312 board with RTD 3.0.0.

Need support.

Attaching the example code for reference.

I am also facing the same issue with 3.0.0 version, but I think it will work for 2.0.3

If you find any solution with 3.0.0 version...let me know.

Hi,

setting HSE_clk to 60MHz would work.

Hi @PetrS

Can you please explain how to set this clock at 60 MHz. At present I see it set at 120 MHz.

I tried to change the frequency using the graphical tool inside the IDE but it showed me an error.

I'm using s32ds3.5

Hi @PetrS . I tried the solution you suggested. It seemed to work initially but again the same issue was faced numerous times. After some investigation we found that the watchdog was enabled by default. Disabling the watchdog seemed to have fixed the issue completely.

Thank you for your support.
