Creating Custom Board File (.mex) for MCUXPresso IDE

SrinathVelavan — Wed, 21 Jun 2023 05:21:04 GMT

Hi,

I am creating a custom board using LPC55S69 as host MCU. For the purpose of adding the custom board to be used with the SDK in MCU Xpresso IDE, I am creating a custom board .mex file.

I have configured the pin map as per my design and now working on the Clocks configuration for the board. Is there any reference for developing a custom board file using LPC55S69 Host MCU?

I am facing difficulties configuring the clocks for the .mex file .

TIA

Hello @SrinathVelavan

What is your issue? Open clock configuration as below:

Then config in left and right parts as below:

And there is a user guide for config tools, attach it for you.

Thanks for the Userguide. I have actually customized the pins as per my design. I am right now doing the clocks but there is no change in the clock sources in my design, I am using the default clock source configuration as per the LPC55S69EVK.

Is the max clock frequency 150MHz for the LPC55S69? Just want to makesure what I have done is right. ( Refer image attached).
