HIP:TS-7000:redboot

Configuring RedBoot for NFS booting

Note:

• If using minicom as your terminal emulator, make sure both hardware and software control are disabled...
• Boot the TS board normally, and then in /etc/sysconfig, edit these two files:

• file: "ifcfg-eth0"

DEVICE=eth0
#IPADDR=192.168.0.50
#NETMASK=255.255.255.0
#NETWORK=192.168.0.0
#BROADCAST=192.168.0.255
BOOTPROTO=static
#BOOTPROTO=dhcp
ENABLE=yes

• and file: "network_cfg"

### Technologic Systems
General Network Configuration File
###
       NETWORKING=yes
       GATEWAY=192.168.0.1
       GW_DEV=eth0
       HOSTNAME="desired name"
       BOOTPROTO=dhcp
       DEFRAG_IPV4=no
       FORWARD_IPV4=no

Then Do the following:

• 1. Boot the board and press Ctrl+C

2. This should drop you into the RedBoot command line

3. "ifconfig -l" should display the current configurations, eg

RedBoot> fconfig -l Run script at boot: true Boot script: .. fis load vmlinux .. exec -c "console=ttyAM0,115200 root=/dev/mtdblock1"

Boot script timeout (100ms resolution): 1 Use BOOTP for network configuration: false Gateway IP address: 192.168.0.11 Local IP address: 192.168.0.50 Local IP address mask: 255.255.255.0 Default server IP address: 192.168.0.11 Network hardware address [MAC]: 0x0F:0x0F:0x0F:0x0F:0x0F:0x0F GDB connection port: 9000 Force console for special debug messages: false Network debug at boot time: false

I would strongly suggest that you write/save the default configurations somewhere.

4. "ifconfig" allows you to edit the bootscript that RedBoot executes at boot time.

5. Leave the first line as it is, by hitting return. >> fis load vlinux

6. Edit the next line to: >> exec -c "console=ttyAM0,115200 ip=dhcp nfsroot=[HOST IP]:[root path on host]"

7. Terminate script with a blank line: >>

8. At this point, RedBoot will prompt for some values interactively, I would suggest you incease the "Boot script timeout" some larger value like 10 (1s), this will give you more time to interrupt RedBoot using the Ctrl+C command.

9. Leave all other values as they are, unless if you really want to change them.

10. The final prompt will ask you to save the changes you made by entering y/n.

11. Reboot the board, it should mount root from the host and path specified in RedBoot.

12. If you experience boot errors, check your host configurations and NFS server configurations.
