      2. 3.1.2  Early versions of the AM571x IDK EVM not installed with SOC devices rated for the full industrial temperature range
      3. 3.1.3  AM571x IDK EVM does not support eMMC HS200 mode
      4. 3.1.4  PCIe PERSTn line not in proper state at start-up
      5. 3.1.5  EDIO connectors J4 and J7 should support real-time debugging for both PRU1 and PRU2
      6. 3.1.6  HDQ implementation not correct
      7. 3.1.7  Removing the power plug and inserting it again while the power supply is energized can cause damage
      8. 3.1.8  Software shutdown of PMIC not operational
      9. 3.1.9  CCS System Reset fails
      10. 3.1.10 AM571x IDK EVM design contains two clamp circuits that may not be necessary
      11. 3.1.11 Crystal connected to osc0 needs to have 50ppm or better long term accuracy
      12. 3.1.12 Software must program the CDCE913 for 0pf load capacitance
      13. 3.1.13 Protection diode D2 should be rated for 5V
      14. 3.1.14 PHY address LSB for U9 and U15 can be latched incorrectly

  8. 4Revision History

2.2.2 TPS6590377 PMIC

The power requirements of the processor are met by the TPS6590377 Power Management IC (PMIC). The power sequencing requirements of the AM571x processor are also handled by the TPS6590377 PMIC. Figure 2-2 shows the supply connections from the TPS6590377 PMIC to the AM571x processor.

Refer to the AM571x Sitara Processors Silicon Revision 2.0 Data Manual (SPRS957) for more information about the required supply voltages and supply sequencing. Also refer to the TPS659037 Power Management Unit (PMU) for Processor Data Manual (SLIS165) and the TPS659037 User's Guide to Power AM572x and AM571x User’s Guide (SLIU011) for details about its operation.

Note that the production version of the AM571x IDK EVM uses the TPS6590377 PMIC that supplies the voltages needed for the latest silicon version of the AM5718 processor. Beta prototype IDK EVM units used the TPS6590375 PMIC and Alpha prototype IDK EVM units used the TPS6590372 PMIC.
