CSI2 LDO Needs to Be Disabled when Module Is Powered On

CRITICALITY

High

DESCRIPTION

Enabling CSI2 LDO shorts it to core supply. It is crucial the 2 CSI2 LDOs on the device are disabled if CSI-2 module is powered on (0x4845 B304 | 0x4845 B384 [28:27] = 0x1) or in ULPS (0x4845 B304 | 0x4845 B384 [28:27] = 0x2) mode. Common concerns include: high current draw on the module supply in active mode.

Errata does not apply when CSI-2 module is powered off (0x4845 B304 | 0x4845 B384 [28:27] = 0x0).

WORKAROUND

CSI-2 module enabled:

Set the following register bits to disable the LDO:

For CSI2_PHY1: Set bit 6 of 0x4845 B828
For CSI2_PHY2: Set bit 6 of 0x4845 B928
