K60 hang issue if use PTE24 and PTE25 for UART communication in MQX4.2 RTOS

[Thiru1]

     Last time I had used MQX3.8 RTOS. It was working properly. Then i upgraded to MQX4.2. I am using K60 kinetics MCU pins PTE24 and PTE25 for UART communication. Some Times the MCU is hanging, even though I set OSC1_CR = 0 and MCG_C10 = 0. I disabled UART communication, then there is no MCU hang issue.  How to solve MCU hang issue.

Hi,

Are you using a custom board?
Which BSP are you using? According you mention I assume you modified the clock configuration, right?  If so, could please let me know all the modifications you made?

Have a nice day!
