How could I disable MPU of K64F

[gloria]

Hi, I am using KDS3.0+KSDK1.2.0 and K64F board. How could I disable MPU because I want to use USB CDC. Which file should I modify to diable it?

Many thank!

Hi

Add

MPU_CESR = 0;

to any code before USB initialisaition.

​Hi Mark,

Should I add any header file?

Hi

You should find the register (possibly with slightly different name) in an existing header file.

In an emergency you can use

*(unsigned long *)0x4000d000 = 0;
