BusFault: A precise (synchronous) data access error has occurred in S32K312, in RTC initialized

LewisThin — Sun, 14 Jan 2024 11:50:02 GMT

I met a fault when initial RTC using mcal

BusFault: A precise (synchronous) data access error has occurred.
Possible BusFault location: 0x40288004.
HardFault: A fault has been escalated to a hard fault.

If I run the program directly, everything is OK

but when i run the program from boot, the program crashed in line 475, the fault is above.

the chip is S32K312

can anybody help?

Hi @LewisThin,

Is PRTN1_COFB1_CLKEN[REQ34] set?

Thank you,

Hi @danielmartynek ,

We are working on S32K322.

We are also facing same issue in Clock_Ip_SetRtcRtccClksel_TrustedCall()

What could be the possible reasons of failing?
