MK10DN512xxx Slow Start

I have PCB with this part I designed in 2012 using CW for MCU V11 and Processor Expert. The external Xtal is 6.144MHz and the PLL boosts to 98.304MHz. The original code had a for() loop timer that was needed before calling MCU_Init() and any other code. If not the CPU did not always start properly (except it always ran fine with JTAG J-Link and IDE). The last time we built the boards was 2013. Now 8 years later we just built some more. Now I find that I need to double the for() loop timer to get the CPU to start reliably. Anyone else seen this issue?

Hi Simon,

Can you give more detail about the problem, like the clock configuration, hardware and what the problem looks like?

 

Regards,

Jing
