system core clock control

[yf2]

Dear support,

I am testing a computing library on RT1170-EVK and I noticed that my SystemCoreClock reads out 528Mhz, not close to 1Ghz as expected.

Is there any simple method to boost the system core clock speed on RT1170-EVK? plain C code fragements are welcomed.

Regards,

yf

Hello
Hope you are well.
You can use config tools from MCUXpresso to generate the code that enables running the core at 1Ghz.

It is important to mention that only consumer grade RT1170 is able to run at 1GHz.

If you have more questions do not hesitate to ask me.
Best regards,
Omar

Thanks a lot for your information.

Currently I am not using the IDE and the "fsl_clock.h" librariess yet. I will see how to use the config tool.

If you know some simple code fragments, please also teach.

Config Tools allows you preview the generated code for that configuration. You can download the standalone version of the tool so you can integrate the configuration on the IDE you are using: MCUXpresso Config Tools|Software Development for NXP Microcontrollers (MCUs) | NXP Semiconductors
MCUXpresso Config Tools currently supports the following toolchains:
• IAR Embedded Workbench
• Keil MDK uVision
• Arm GCC

If you have more questions do not hesitate to ask me.
Best regards,
Omar

Can I assume that the MCUXpresso Config Tools is not specific for EVK boards but also apply to customer boards?

You´re correct, since the tool focus on the MCU.
