When dealing with a corrupted flash or related issues, follow these steps to troubleshoot and resolve the problem.

Boot Loop Process

When a unit is stuck in a boot loop and fails to stabilize, the first step is to console into the unit directly and review the boot process. This can provide insights into why the unit is not booting correctly.

Example Error:

Booting image from Secondary

Wrong Image Format for bootm command

ERROR: can't get kernel image!

could not boot from secondary, no valid image; trying to boot from primary

Booting image from Primary

Wrong Image Format for bootm command

ERROR: can't get kernel image!

Console the Unit:

Connect to the unit via a console cable and monitor the boot process. Interrupt the boot process by pressing b at the boot counter.

Set Up for Recovery:

Connect an Ethernet cable from the management port to the TFTP server.
Ensure the device is in boot mode for recovery.

Example:

Configure Environment Variables:

Set the TFTP server IP and other necessary network settings.

ICX 7450-48> setenv serverip 10.10.10.21

ICX 7450-48> setenv ipaddr 10.10.10.22

ICX 7450-48> setenv gatewayip 10.10.10.1

ICX 7450-48> setenv netmask 255.255.255.0

ICX 7450-48> saveenv

Verify the settings:

ICX 7450-48> printenv

baudrate=9600

ipaddr=10.10.10.22

gatewayip=10.10.10.1

netmask=255.255.255.0

serverip=10.10.10.21

uboot=ruckus/ICX7450/bootcode/spz10115

Version:10.1.06T215 (May 15 2015 - 11:28:23)

Test Connectivity:

Ping the TFTP server to ensure connectivity.
Disable the Windows Firewall

ICX 7450-48> ping 10.10.10.21

ethPortNo = 0

Using egiga0 device

host 10.10.10.21 is alive

Update the Flash:

Set the image file name and update the flash.

ICX 7450-48> setenv image_name images/ICX/SPR08090.bin

ICX 7450-48> update_primary

For versions below 8080f, update the uboot file.

Provide the file name of the boot image to be copied from the tftp server.

ICX 7450-48> setenv uboot <xxx.bin>

ICX 7450-48> update_uboot

Boot the Unit:

Load the image from the primary or secondary flash.

ICX 7450-48> boot_primary
