Help Configuring RT595 clock

Hello All,

Please, I need some help reconfiguring the RT595-EVK board clocks. I am new to the RT595 and most NXP Cortexes.

I want to connect the LPC5536 I3C as Master running I3C @37.5MHz to the RT595 as Slave. I believe that the I3C sample code for the RT595 is running at 396MHz and the I3C (DIV 4) at 99MHz

I need to figure out a common I3C clock for both boards. either I bring the RT595 down to 37.5MHz or I find a common clock that works for both boards. The PLL for the LPC is running at 150MHz and the I3C (DIV 4) 37.5MHz

I am attaching the clock files for both boards to this post.

Can anyone please help me?

Thank you!

#LPC5536 #LPC5569 #i.MXRT595

Hi,

I have tried to use MCUXpresso config tools to configure the I3C clock for only LPC5536, I attach the screenshot here:

Pls check if you configure it correctly
