MK60FN1M0VLQ15/MQX clock configuration

[pasini]

Hi

I am using MK60FN1M0VLQ15 and MQX with IAR IDE.

I have an external 4MHz cristal as clock source.

Where and how do I set the clock registers to make the MCU work in this frequency with USB interface ?

Do I have to change bsp_cm.c ( hard coded ) ?

It seems all macros in bsp_cm.h as useless. creepy.

Thanks

Luiz

Hi Luiz,

Are you using MQX_4.1.1?

If yes please review Section 4.1 of C:\Freescale\Freescale_MQX_4_1_1_GA\doc\mqx\MQX_BSP_Porting_Example_User_Guide.pdf

And C:\Freescale\Freescale_MQX_4_1_1_GA\doc\mqx\MQX_BSP_Porting_Guide.pdf

This explains how to use IAR with PE to change clock configuration.

Regards,

David
