Dear Officer,

We had a SK32K146 EVB board working fine previous, and the demo can be run.

After I downlown my program(via OpenSDA-USB port) in S32DS, at the first, I can debug it. But some error in my program, the breakpoint jump to the default_isr. so I disconnect it and modify my source code. Then I download again. However, the below dialog box will be shown.

I close it, the new dialog box as below:

I have search the related topic on NXP Community, may be they are no help. So I post it again.

The 5V power is OK(J107).

MCU 5V (J15) is OK.

It may be the PLL clock is not init normally.

Please give me some help, I'm at a loss, because the EVB was reveived last day, and it can not use.

Thanks a lot !

I have already solved this problem.

At first, I download a J-Link Commander, and want to erase the chip. But can't connect to target. And the command line shows that "Communication error while accessing MDM-AP."

So I search it in community, and a post shows me a similar situation.
