Set Core Clock of iMXRT1011 to 400 MHz

[Masmiseim]

Hello community,

is there an example available of how to clock the core of the #MIMXRT1011CAE4A (400 MHz)? In the SDK is only an example for#MIMXRT1011DAE5A (500 MHz) available

The PLL6 is used as a clock source to reach the 500 MHz. For 400 MHZ PLL3_PFD3 or PLL2_PFD3 must be used. I could get this running when started by the debugger, but it will not boot anymore.

Regards

In the meantime a new Version of the SDK is released which contains beside the 500 MHz also a 400 MHz configuration example.

This one work as expected.

Hi,

You can make use of ConfigTools and the clocks tool to modify the core frequency.

Best regards, Daniel.
