      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

2.11.2 GPIO Pin Mapping

The developer can enable GPIO pins individually, as needed, as output, input, or both. Most of the LVCMOS pins not currently allocated for other peripheral use can be defined as GPIO pins. Table 2-5 is a compliment to the schematic and the recommended settings in the pinmux tool. Each of the defined GPIO pins are listed along with the associated pin name and ball number and mode. The last column lists the available physical pull-up (PU) or pull-down (PD) resistor attached or the recommended internal pull-up or pull-down resistor defined in the pinmux file provided for the AM571x IDK EVM.
