Appendix A Known Deficiencies in Am571X IDK EVM
38
Power Solution Not Sufficient for Full Pcie Plug-In Card Compliance
38
Early Versions of the Am571X IDK EVM Not Installed with SOC Devices Rated for the Full Industrial Temperature Range
38
Am571X IDK EVM Does Not Support Emmc HS200 Mode
38
Pcie Perstn Line Not in Proper State at Start-Up
38
EDIO Connectors J4 and J7 Should Support Real-Time Debugging for both PRU1 and PRU2
38
HDQ Implementation Not Correct
38
Removing the Power Plug and Inserting It Again While the Power Supply Is Energized May Cause Damage
38
Software Shutdown of PMIC Not Operational
39
CCS System Reset Fails
39
Am571X IDK EVM Design Contains 2 Clamp Circuits that May Not be Necessary
39
Crystal Connected to Osc0 Needs to Have 50Ppm or Better Long Term Accuracy
39
Software Must Program the CDCE913 for 0Pf Load Capacitance
39
Protection Diode D2 Should be Rated for 5V
39
PHY Address LSB for U9 and U15 Can be Latched Incorrectly
40
3.3-V Clamp Circuit Needs more Margin
40
Current PMIC Does Not Provide the Mandated Power down Sequence
40
Power Supply Droop May Cause Board Reset
40
AM5718 Pin N21 Must be Connected to 1.8 V, as It Is VDDS18V_DDR1 and Not N/C
40
