Hi community,

 

I want to confirm about i.MX6DQ PMU.

I understand i.MX6DQ works 792MHz and LDO Enabled mode after iROM code is read when boot sequence, doesn't it?

Then, would you let me know the i.MX6DQ LDO output voltages (VDD_ARM_CAP and VDD_SOC_CAP) after iROM code is read?

 

According to chapter 50.7.4 in IMX6DQRM (Rev.2), the initial settings for VDD_ARM_CAP and VDD_SOC_CAP seem 1.100V after reset.

But these are not satisfied the operating ranges when 792MHz LDO enabled mode.

So I think the LDO voltages are changed by iROM code.
