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. 35 36choice 37 prompt "State of Run LED" 38 default PDU001_RUN_LED_RED 39 help 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. 45 46config RUN_LED_RED 47 bool 48 prompt "Red" 49 help 50 Lit Run LED red. 51 52config RUN_LED_GREEN 53 bool 54 prompt "Green" 55 help 56 Lit Run LED green. 57 58config RUN_LED_OFF 59 bool 60 prompt "Off" 61 help 62 Do not lit Run LED. 63 64endchoice 65 66endif 67
