About output between VDD_PU and VDD_SOC LDO in i.MX6DQ.

Dear All,

 

Refer to the Note of Table 6. Operating Ranges in IMX6DQAEC(Rev.4).

======

6  VDD_SOC_CAP and VDD_PU_CAP must be equal.

7  VDD_SOC LDO output set point is equal to the VDD_PU LDO output set point.

======

 

But, VDD_PU LDO is off in uboot or DVFS processing with VDD_SOC LDO enabled in jb4.2.2_1.1.0.

Does this have the possibility to cause a problem?

(Some issue wasn't seen on custom board.)

 

Best Regards,

Keita
