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.
