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 five seconds to let the bootloader know that you are going to
override the default root file system. After you hit <enter> the bootloader will boot the factory root
file 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 file system
upgrade and re-perform it.
Performing the Linux Subsystem Kernel Upgrade
First you need to download the Linux Subsystem Kernel firmware 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 file to your Sonoma using either
ftp
or
scp
. If you are using
ftp
, transfer the
previously downloaded file using
binary
transfer mode from the remote host to this specific file 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 file}
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:
upgradekernel
