nect the Serial I/O Port and Test the Serial I/O Port for setup details. When you have connected
your terminal to the serial I/O port, apply power to the Sonoma.
Pay close attention to the terminal window while the unit is rebooting. After the Linux bootloader
displays the message
Default kernel: FACTORY
To override and boot the UPGRADE version of the kernel,
type UPGRADE within 5 seconds
.....
Booting with FACTORY Kernel
Default Root File System: UPGRADE
To override and boot the FACTORY version of the Root File System,
type FACTORY within 5 seconds
you must begin typing “factory” within ve seconds to let the bootloader know that you are going to
override the default root le system. After you hit <enter> the bootloader will boot the factory root
le system. Watch the rest of the boot process to make sure that you have successfully recovered. If
the system boots normally, then you should resolve the problems with the previous root le system
upgrade and re-perform it.
Performing the Linux Subsystem Kernel Upgrade
First you need to download the Linux Subsystem Kernel rmware from the EndRun website to a
place on your network which is accessible to the Sonoma. The link to the Sonoma upgrade page is
shown above.
You may transfer the le to your Sonoma using either ftp or scp. If you are using ftp, transfer the
previously downloaded le using binary transfer mode from the remote host to this specic le on
your Sonoma: /tmp/kernel.gz. The kernel image will be named with a software part number like:
6010-0064-000_2.00.uImage. When following the instructions below, substitute the name of the
actual kernel image that you are installing for 6010-0064-000_2.00.uImage. Issue these commands
from the console of your Sonoma:
ftp remote_host {perform ftp login on remote host}
bin {set transfer mode to binary}
get 6010-0064-000_2.00.uImage /tmp/kernel.gz {transfer the le}
quit {close the ftp session after transfer }
If you are using scp, you may open a command window on the remote computer and securely
transfer the kernel image from the remote computer to your Sonoma. A command like this should be
used:
scp –p 6010-0064-000_2.00.uImage root@host.your.domain:/tmp/kernel.gz
Now issue the following command to the Sonoma console to initiate the upload:
