S32K344 Sampleprojects run into a hardware fault

[JoDo]

Hello,

I am working with a S32K344 controller and a S32K3x4EVB_Q257 Evalboard. When I load a compiled sample project from the S32K3 RTD package, the controller runs into a hardware error. When I load the same project into RAM, everything is fine.

I did some debugging and there seems to be a problem with the clock tree, specifically the PLL configuration. However, the Clock_Ip_DistributePll() function in the Clock_ip.c file is causing the hardware error (but not in RAM debugging mode).

I used a new workspace and several sample projects from the S32K3 RTD package (v1.0. Code Drop 01).

Does anyone have any idea what can cause this behavior?

thanks!

Hi, I have similar problem.. Not example but my project also using Clock_Ip and first time with Debug Flash everything works fine. Second time I get bus and hard fault. I have to reset board than and again it will work once than hard fault..

Hi, 

For me also getting same issue for I2C, CAN and UART example programs. It is going to HardFault_Handler. Did anyone know the issue?

Thank you

Hi, 

it is some particular example or all of them? I got some issue with ADC example - the example ends in exception. But other examples works okay.

Hello,

as @kranthi wrote, I have the same exception in several examples e.g. in UART "LpuartFlexio_Uart_Ip_Example_S32K344". But the Hard Fault Exception only occurs when the project is loaded into the FLASH. Loading the same project into RAM does not generate an exception.
