Chapter 9. Appendix
This chapter explains how to recover Eddy when flash of Eddy is damaged and it cannot be booted.
9.1 System recovery via Bootloader
Even if the flash in the user area has been damaged, it does not affect system booting. But if the system
continuously reboots due to user program failure, or if the system is inaccessible as a result of wrong IP setting, you
have to change the system to factory default status.
You can reload firmware from bootloader to change the system to default status. In order to do this, TFTP server has
to be installed at the computer with Linux environment.
Note:
Once the bootloader is damaged, it cannot be recovered. Therefore user should not use command
other than ones provided from manual.
9.1.1 Installing TFTP in Linux environment
The following explains how to recover system with bootloader in Fedora core 5 operating system.
If you are using other operating system, you will need tftp-server and xinetd daemon compatible with that operating
system.
First check to make sure tftp-server is installed.
If you don’t install tftp-server, you should install.
After install tftp-server, move provided firmware (firmware folder in SDK folder) to tftpboot folder (usually /tftpboot
folder in Fedora core 5).
