The AM335x SoC has a total of 6 UARTs (UART0 to UART5 as referenced
in documentation, etc) available to it. The best choice for the
PDU001 is UART3 as it is wired to the header K2; enter 4 here to
use UART3. UART0 is connected to the EIA-485 transceiver. If you
really need to use it, you are advised to remove the transceiver U14
from the board. UART1 is wired to the backplane and therefore
accessible from there or by the backplane connector K1 of the PDU.
Any other UART then UART3 (enter 4 here), UART1 (enter 2 here) or
UART0 (enter 1 here) are not sensible since they are not wired to
any connector and therefore difficult to access.

Summary
=======
This document covers the PDU001 target.
Hardware
========
The PDU-001 (Processor and Display Unit) is a plugin card for 19" racks. It is
manufactured by EETS GmbH (https://www.eets.ch). The core of the board is a m2
SOM from bytes at work (https://www.bytesatwork.ch) which in turn is based on
AM3352 SOC from TI (http://www.ti.com).
Customization
=============
As usual the console serial interface is set by CONFIG_CONS_INDEX. Best choice
is 4 here since UART3 is wired to the connector K2.
The Run LED on the PDU-001 can be turned on red by setting CONFIG_RUN_LED_RED
or green by setting CONFIG_RUN_LED_GREEN. Setting CONFIG_RUN_LED_OFF will turn
off the Run LED.
Booting
=======
The system boots from either eMMC or SD card cage. It will first try to boot
from the SD card cage. If this fails (missing or unbootable SD card) it will
try to boot from the internal eMMC. The root file system is always expected to
be located in the second partition of the device (eMMC or SD card) that pro-
vided the boot loader.
