Unhandled Interrupt code is executed for SKEAZN8MFK4 MCU when using Processor Expert to configure FTM0

[juliusjai]

Hello, I'm using CW MCU v10.7 and trying to configure Processor Expert for SKEAZN8MFK4 MCU.

I'm configuring FTM0 to test timer interrupt. When the code executes void FTM0_Init(void), the OpenSDA debugger stops and triggers PE_ISR(Cpu_Interrupt) -> Unhandled Interrupt Code.

PE_ISR(Cpu_Interrupt)
{
/* This code can be changed using the CPU component property "Build Options / Unhandled int code" */
PE_DEBUGHALT();
}

Additional details:

Evaluation Kit used is TRK_KEA128.

All I have is PE generated code, so I assume everything should be working.

Any idea why Unhandled Interrupt is executed with the above conditions?

Hello Alice,

I have attached the project in my original message above.

Thanks for the help.

Hi Julius,

I tested your project on my side, it can work well .

Please check whether you choose the right chip when debug , have a alook bout my attachment video .

Hope it helps

Have a great day,

Hello Alice,

I followed exactly your video and I can confirm I'm setting the right MCU that is KEAZN8M4.

By the way, are you also using TRK_KEA128 for demo board?

Thanks.

Julius

Hello Julius,

I'm really not sue why you create a KEAZN8M4 project on TRK-KEA128 board ,

if you use TRK-KEA128, you can create the KEA128 board, and when debug , please choose the

target KEAZ128M4, not the KEAZN8M4.

Hope it helps
Have a great day,

Hello Alice,

My final hardware design will be using KEAZN8 that's why I would like to create a KEAZN8 project.

Currently, I only have TRK-KEA128 evaluation kit.

So, can you please confirm if you are using a KEAZN8 evaluation kit when you tested my project?

At least I can narrow down the issue, and maybe I don't have to continue investigating why KEAZN8 is not working with TRK-KEA128 evaluation kit.

Thank you.

Julius

Hello Julius,

Yes, I use the demo board "TRK-KEA8"(SKEAZN8MFK4), it can work well.

The address of SIM_SCGC is different between KEA8 ank KEA128( you can checked it on Reference manual ),

For KEA8:

For KEA128:

so when you download the KEA8 project into TRK-KEA128,  this enable FTM0 clock gate code can't enable the FTM0 clock.

  /* SIM_SCGC: FTM0=1 */
  SIM_SCGC |= SIM_SCGC_FTM0_MASK;

then when you operate FTM0 registers, it will run into Hard_Fault interrupt .

Hope it helps

Have a great day,
