BusFault: A precise (synchronous) data access error has occurred

[fedotech]

Hi, 

I'm trying to integrate ccp protocol, the hardward platform is S32K144EVB.  when I copy a string variable, I encountered the following problems：

the console says:

Interrupt command received. Halting execution.
BusFault: A precise (synchronous) data access error has occurred.
Possible BusFault location: 0x09430040.
HardFault: A fault has been escalated to a hard fault.

Could somebody help me? Thanks!

HARDFAULT, thanks.

Hi,

For some reasons, it accesses an unimplemented memory:

Do you have the exact instruction that causes the bus fault?

If so, please double check the pointers in the code.

Hi, I fixed the issue. It's because CANape send a Motorola address. Thanks!
