Known Deficiencies in AM572x IDK EVM

A.20

Current PMIC does not provide the mandated power down sequence

The current PMIC does not provide the mandated power down sequence as shown in the

Processors Silicon Revision 2.0 Data Manual (SPRS982)

. Production IDK EVMs contain the TPS6590377

PMIC, which powers off the DDR supply at the wrong time. The default programming has been corrected
in the TPS6590379 PMIC. This part will be used for future builds.

A.21

PMIC OSC16MCAP pin mistakenly grounded

The OSC16MCAP pin on the TPS659037x PMIC should be connected to a 2.2-

μ

F capacitor to ground.

Unfortunately, all versions of this IDK EVM have this pin connected directly to ground. Although there are
many IDK EVMs in use, connecting the OSC16MCAP pin directly to ground may damage the
TPS659037x PMIC. Operation may become erratic or it may fail completely. Designs that copied this
design mistake must be corrected.
