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. choice prompt "State of Run LED" default PDU001_RUN_LED_RED help The PDU001 has a bi-color (red/green) LED labeled 'Run' which can be used to indicate the operating state of the board. By default it will be lit red by U-Boot. Later in the start-up process it can be changed to green (or heartbeat or anything else) by the kernel or some other software. config RUN_LED_RED bool prompt "Red" help Lit Run LED red. config RUN_LED_GREEN bool prompt "Green" help Lit Run LED green. config RUN_LED_OFF bool prompt "Off" help Do not lit Run LED. endchoice endif
