Hello Champs,
In the Errata ERR005852 "Analog: Transition from Deep Sleep Mode to LDO Bypass Mode may
cause the slow response of the VDDARM_CAP output".
The workaround is "The software workaround to prevent this issue it to switch to analog bypass mode (0x1E), prior to
entering DSM, and then, revert to the normal bypass mode, when exiting from DSM"
Does this mean that 11110(0x1E) is a special value which turns digital LDO into "analog bypass mode"?
Best regards,
Nori Shinozaki
Solved! Go to Solution.
Hi Nori
LDO "analog bypass mode" IMX6DQRM
sect.50.7.4 Digital Regulator Core Register (PMU_REG_CORE)
is value:
11111 Power FET switched full on. No regulation.
so description in errata can be considered as misprint.
Best regards

Hello Igor,
Thanks! So you mean, 0x1E is typo in the Errata, 0x1F is a correct value to turn on analog bypass mode?

Hi Nori
yes 0x1F is a correct value
