MMPF0100 in u-boot

[JHY]

Hi,

Below data on i2c in u-boot is from SABRE-SDB but I think it is not from PMIC.

=> i2c probe

Valid chip addresses: 08 48

=> i2c md 0x08 0 10

0000: 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10    ................

How can access register in PMIC?

Hi JHY

had you implemented patch

I2C command in 2014.01 u-boot on sabresd

also could you try exlicitly set address and read data one by one

(without autoincrementing): i2c md 0x08 0.., i2c md 0x08 1.., i2c md 0x08 2..

Best regards
