How does core clock affect uboot/kernel?

[alain_olivier]

Hello,

I plan to use IMXRT1021 for a project, but I notice the industrial and customer versions have a different core clock, 400 MHz and 500 MHz respectively. Is switching from one to the other something transparent or does it require uboot/kernel adjustments?

Thanks,

Alain.

Hi Alain Olivier

The difference between the Industrial and the Consumer is the temperature range, level of accuracy with the voltage, freq, etc. So this is why the Frequency change between that datasheet. Since the image for uboot is chip specific, there should not change anything on this, but the uboot image should consider what chip would use.
