HIP:TS-7000:redboot

Configuring RedBoot for NFS booting

Note:

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

• file "ifcfg-eth0" to:

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" to:

### 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 vmlinux

6. Edit the next line to:

>> exec -c "console=ttyAM0,115200 ip=dhcp nfsroot=[HOST IP]:[root path on host]"

e.g. Booting pmp3 from stewie

>> exec -c "console=ttyAM0,115200 ip=dhcp nfsroot=159.28.230.34:/home/hip/nfs-boot/tslinux-pmp3"

7. Terminate script with a blank line:

>>

8. At this point, RedBoot will prompt for some values interactively, I would suggest you increase the "Boot script timeout" to 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 now mount root from the host and path specified in RedBoot.

RedBoot> reset
... Resetting.

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