Hi,

 

I have a K70 Tower setup and am not getting past a while loop in the BSP.  The comment is "Wait until external reference clock is selected as MCG output.".  This is line 990 in file bsp_cm.c.  The code is:

 

  while((MCG_S & 0x0CU) != 0x08U) {/* Wait until external reference clock is selected as MCG output */

 

I am fairly sure I have my jumpers in the processor board set up exactly like my co-worker's.  And he has been able to run his code just fine.  There are differences between my code and his.  But there should be no difference between at the BSP level.

 

Knowing what to look for (i.e. jumper configuration or code) would be a great help.

 

-thanks
