…workaround

Update documentation for USB1 low power mode limitation on SK-AM62-LP and SK-AM62P-LP E1/E1-1 EVMs. When USB1 is connected during low power mode entry, the EVM fails to resume to an active Linux state.

Hardware workaround is provided for both platforms:

  • SK-AM62-LP: Remove resistor R131
  • SK-AM62P-LP E1/E1-1: Remove resistor R169

… limitation

Add documentation for USB1 low power mode limitation on SK-AM62-LP and
SK-AM62P-LP E1/E1-1 EVMs. When USB1 is connected during low power mode
entry, the EVM fails to resume to an active Linux state.

Provide hardware workaround for both platforms:
- SK-AM62-LP: Remove resistor R131
- SK-AM62P-LP E1/E1-1: Remove resistor R169
