Hi, I use i.MX6 Android KK4.4.2 BSP. I noticed the CPU run at 792MHz because I can see the following message when uboot boots up:

CPU: Freescale i.MX6 family TO1.5 at 792 MHz

Could anyone let me know how to change i.MX6 CPU frequency to 1GHz or 1.2GHz? Thanks!

Hi Rita,

Thanks for you reply! I can now change CPU frequency to 1GHz based on your info. I will study if it can be changed to 1.2GHz.

We have some i.MX6Q chips which support 1.2GHz.
