Note: This is the second revision of the User Guide. For any
questions or points of clarity, refer to
E2E®.
Note: If only the red power status LED (LD14) is on during
power-up then the connected power supply is not able to successfully negotiate power
delivery with the PD controller on the EVM. This means that the power-up sequence is
not initiated and that connecting to the SoC is not possible. A PD-capable power
adapter is required for this EVM.
Note: The E2 Revision of the AM275x EVM board is identical to
Revision A of the AM275x EVM board.
Note: The E1 revision of the EVM has a known issue surrounding
BOOTMODE8 logic during power-up and reset. BOOTMODE8 has two buffers that can both
drive during bootup and created unexpected states on BOOTMODE8. With BOOTMODE8 in an
unexpected state, any bootmode that depends on BOOTMODE8 configuration are affected.
For more details on bootmode configuration, see the
Boot Mode Selection.
Veify that J22 is not connected
during power-up and reset to have proper BOOTMODE8 values.
All other bootmode signals and
configurations are unaffected.
Note: External power supply or power accessory requirements:
- Nominal output voltage:
5VDC
- Max output current:
3000mA
- Efficiency Level V
Note: TI recommends using an external power supply or accessory
that complies with applicable regional safety standards such as (by example) UL,
CSA, VDE, CCC, PSE.
