MKM34's code stop at FLL Initial (IAR 7.7)

Hi~

In the mass production project, several MKM34 could not write the program through J-LINK.

After tracking the code, it was found that the code would stop at  WAIT_FOR_FLAG (MCG_C1, CLKS, CLKST).

I tried many ways, and finally found that the program can be downloaded normally under the same settings of IAR version 7.2, but it will stop at FLL Initial in version 7.7 of IAR.

 

Please give some comments~

Thanks
