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.

- 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>
