Host Computer Configuration

Install tftp onto the Linux host computer

For CentOS I used yum

yum install tftp

yum install tftp-server

then I looked in the file

/etc/xinitd.d/tftp

1. default: off
2. description: The tftp server serves files using the trivial file transfer \
3. protocol. The tftp protocol is often used to boot diskless \
4. workstations, download configuration files to network-aware printers, \
5. and to start the installation process for some operating systems.

service tftp

{

       socket_type             = dgram
       protocol                = udp
       wait                    = yes
       user                    = root
       server                  = /usr/sbin/in.tftpd
       server_args             = -s /tftpboot
       disable                 = yes
       per_source              = 11
       cps                     = 100 2
       flags                   = IPv4

}

to see how tftp was configured by default. The file tell me that the tftp files should be located in the subdirectory

/tftpboot

turn the server on

/sbin/chkconfig tftp on

Download files from JLAB

I downloaded the boot file and VXworks kernel from JLAB

/site/coda/kern/5.5/boot/boot6100_122.bin  
/site/coda/kern/5.5/vx6100_v4.1 

Debug Connector

I then used the serial port on the host computer to interface with the MVME6100 via the "DEBUG" port. The debug port took an RJ45 standard cable so I got and RJ45-DB9 converter. This seemed to work out of the box. Just in case I ever need to make my own connector record the pinouts below.

Information below is Table 5-11 pg 92 of this reference

ROC Pin#	DB9 Pin #	DB9 shell	Signal
1	1	Blue	DCD (Carrier Detect)
2	7	Orange	RTS (Request to Send)
3	5	Black	GNDC
4	3	Red	TX (Transmit)
5	2	Green	RX (Recieve)
6	5	Yellow	GNDC
7	8	Brown	CTS (Clear to Send)
8	4	White	DTR (Data Terminal Ready)

Load in the VxWorks boot kernel

MVME6100> tftpGet -cCLIENT_IP_ADDRESS -sSERVER_IP_ADDRESS -fFILENAME

CLIENT_IP_ADDESS is the IP address of the computer receiving the file
SERVER_IP_ADDRESS is the IP address of the computer hosting the file (by default tftp uses the subdirectory /tftpboot)

Flash the RAM with the program

>MVME6100>flashProgram -d/dev/flash0 -o03f00100 -nfff00

After flashing you flip dipswitch #2 on S4 fo off and powercycle
