To change LPDDR4 1.1V voltage on imx8m evk

[mikesu]

Hi! Sir,

We want to change LPDDR4 1.1V voltage from 1.1v to 1.05V on imx8m EVK .

It is very useful to verify LPDDR4.

But we do not have any idea how to change the register value of PF4210 .

Could you teach us how to change LPDDR4 1.1V voltage on IMX8M EVK?

Thanks!

Mike

HI

In SW2 setup and control registers(ADD 35-SW2VOLT) setting SW2[6:0] as 0011010 by IIC then you can get the 1.05V SW2 output.
