ML310 With Linux

From RCSWiki

Step 1. Set up hardware

(a) take main board and power supply out of box
(b) ground yourself and plub in DDR SDRAM
(c) plug in serial cable -- red (stipple/black) pin1 belongs closest to edge of board (this is the FPGA UART jack, J4)
(d) plug in IDE cable to PRI IDE -- red (stipple/black) pin1 is closest to the LEDs and red switches (not edge of board)

   NOTE:  the connectors on the ml-310 board are HALF keyed; many cables assume that one of the male pins on the board have been remove and, on the ml-310, it has NOT been removed. Drill
   out the filling for one cable.   

(e) connect the power supply to the main board and to the IDE disk

Step 2. Hook up host and power on.
(a) connect a serial cable to the back of the PC and plug it into the FPGA UART (J4) cable. Some RS-232 cables are straight-through and some are null modems. You want a null modem. If you have a straight-through cable you put a null modem adaptor inline.
(b) start up minicom (I like kermit but Linux seems to have adopted minicom) to set up the parameters:

   minicom -s 
 
                                                                                                                                                                     
   This will take you straight to the configuration menu.  press the down arrows to menu option "Serial port setup", hit return. Make sure that A shows  "/dev/ttyS0" (assuming you plugged the
   ml-310 serial cable into COM1).  Next make sure E says "9600 8N1" Finally, turn off hardware flow control.  (Maybe this last step is not needed -- I'm just being conservative.)
   Escape to go to the main menu. 

                                                                                                                                                                     
   SAVE AS DEFAULTS and EXIT.  At least one version of minicom saves the results as defaults but doesn't use those defaults until you restart it.
                                                                                                                                                                     

(c) Alright... moment of truth. Turn on power. The green LEDs should flash, then all light, then go off and progress back to being all on. Meanwhile you should get a power-on test on the minicom screen:
