WDOG_CS not showing correct value in debug mode using Jlink

MithileshKumar — Fri, 20 May 2022 13:21:13 GMT

Hi,

I am using MKE15Z series MCU. As per datasheet the default value of WDOG_CS should be 0x2980 but what obtained is 0x420 which is incorrect. But with CMSIS-DAP getting the correct value.

Is it related to debugger. If yes, is there any workaround for this.

Hi MithileshKumar,

Did you try to read the value of WDOG_CS through code? Check if the value is the same as the debugger register view?

If you still have problems after updating the J-Link software, it is recommended to submit a technical service request to SEGGER.

Best Regards,
Robin

Yes I am trying to read through code. At startup, the register view for WDOG_CS is shared in the image. But the reset value of the register should be 0x2980(As per datasheet).
