21 int "UART used for console"
25 The AM335x SoC has a total of 6 UARTs (UART0 to UART5 as referenced
26 in documentation, etc) available to it. The best choice for the
27 PDU001 is UART3 as it is wired to the header K2; enter 4 here to
28 use UART3. UART0 is connected to the EIA-485 transceiver. If you
29 really need to use it, you are advised to remove the transceiver U14
30 from the board. UART1 is wired to the backplane and therefore
31 accessible from there or by the backplane connector K1 of the PDU.
32 Any other UART then UART3 (enter 4 here), UART1 (enter 2 here) or
33 UART0 (enter 1 here) are not sensible since they are not wired to
34 any connector and therefore difficult to access.
37 prompt "State of Run LED"
38 default PDU001_RUN_LED_RED
40 The PDU001 has a bi-color (red/green) LED labeled 'Run' which
41 can be used to indicate the operating state of the board. By
42 default it will be lit red by U-Boot. Later in the start-up
43 process it can be changed to green (or heartbeat or anything else)
44 by the kernel or some other software.
