Question about WM8962 without PMPF0100 PMIC.

Question asked by edwin rose on Aug 15, 2013
Latest reply on May 8, 2014 by Public Account

Hi All,

Now I'm developing the freescale i.MX6 platform.

For cost down purpose, I use discrete power solution without PMPF0100 PMIC.

Now I meet a issue about audio WM8962. It seems can't detect WM8962 as the following console.

I'm trying to disable the I2C signal to PMIC on SABRE Board, the same result with can't detect WM8962.

Both power and I2C are normal.

 

Please help me, thank you very much!
