How can I output the current clock speed the MCU is setup for / running at? As the iMXRT1062 comes in Industrial and Consumer versions, and I'd like to state the clock speed right at boot.
Solved! Go to Solution.
Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) How can I output the current clock speed the MCU is set up for / running at?
-- In the SDK library, it provides the CLOCK_GetFreq() function to get the clock frequency for a specific clock name, and I've attached its code below.
Have a great day,

Where's the code?
Hi,
Sorry, I forgot to attach the code before, and please check it below.
