Wrong Image Format for bootm command, ERROR: can't get kernel image!

adf10 — Fri, 21 Apr 2023 16:24:01 GMT

I have an AP7532 which does not boot, connecting with the console it reports Error message: Wrong Image Format for bootm command", "ERROR: can't get kernel image!" as you can see here:Error

I've waited or max failed attempts but it does not happen.

If I press ESC before loading runtime image it let me in with a basic CLI and I can see some commands that suggest an image could be loaded via tftp.

Can you help me with instructions on how to do this and, is the image the file we use to upgrade the firmware?

Thank you in advance for your help

Check if the kernel image file is in the correct format for your platform. The boot loader typically requires that the kernel image file be in a specific format, such as ELF or Binary. Make sure that the kernel image file is in the correct format. Flying Together

Check if the kernel image file is corrupted. The error message may indicate that the kernel image file is corrupted or damaged. Try downloading or copying the kernel image file again from a reliable source and make sure it is not corrupted.

Check if the file system is supported. The boot loader may not support the file system used by the kernel image file. Try formatting the file system to a supported file system.

Check if the boot loader configuration is correct. Make sure that the boot loader configuration is set up correctly to load the kernel image file. Double-check the configuration file and make sure it is configured correctly.

The most likely problem with this device is flash memory corruption. Try booting it's secondary FW. If it fails as well register RMA and send this device for replacement - it should still have a "limited lifetime warranty".

use help to see the commands

when i remember right you can use "printenv" to see the config and "setenv" to change the settings.

you´ll see the ip of the ap, i think the gateway address and the configured address of the tftp server.

you can try to load the ap image and boot it

take the LEAN image without the gui

Images supplied by Zebra are for their internal firmware flashing utility and I doubt if it would be possible to flash them in using low level "BIOS" utilities.

Thank you for your suggestion, I've been trying to do as you mention, however Image is downloaded but not booted. I'm using bootp which acording to help can boot a downloaded image from tftp , I also used tftpboot with the same result. Do you know any other procedure to do this?

unfortunatelly i don´t have ideas anymore.

best would be to open a gtac case for a rma.

ap should have limited lifetime waranty as far as i know.
