How to change DDR voltage setting before DDR calibration

Dear all,

Our product uses i.MX6UL and PF3000.

For some special reason, we need to change the DDR voltage setting before performing the DDR calibration.

I think that is possible by using Plugin instead of DCD.

Is there any helpful information on how to access the PMIC using assembler?

BR,

George

Hi George

 

unfortunately I am not aware of assembler examples, in general

one can look at baremetal sdk PF0100 (similar to PF3000) example

https://github.com/RT-Thread/rt-thread/blob/master/bsp/imx6sx/iMX6_Platform_SDK/sdk/common/pmic/pfus...

 

Best regards

Dear @igorpadykov 

Thank you very much for your reply.

I see, I will try coding with reference to the SDK.

*Please let me know if you find any other better way.

 

BR,

George.
