Enable Spread Spectrum on IMX8M-Mini

As title, I just find the IMX8QX-Plus has official Spread Spectrum instruction as following:

User Guide of Spread Spectrum Support for i.MX 8QuadMax and i.MX 8QuadXPlus Display

But there are many difference between IMX8QX-PLUS and IMX8M-Mini, I need IMX8M-Mini relate instruction, does the NXP official can provide it? Thanks a lot

Hi May

unfortunately I am not aware of similar documentation for i.MX8M Mini, but

it is supported and described in sect.5.1.5.4.4 SSCG and Fractional PLLs i.MX8M Mini RM

i.MX 8M Mini Applications Processor Reference Manual

So how to implement spread spectrum on IMX8M-Mini, I have no idea after I saw that section of RM file as you send, do you have example codes?

Thanks

Hi May

unfortunately I am not aware of example codes. So you will have to

develop them himself or apply for help to Commercial Support and Engineering Services | NXP

to develop them.
