wnap 320 - firmware recovery

[Alexandro]

Good day
Need help restoring firmware.
After turning on the wireless point, it hangs.
connected the wireless point through the COM port and saw an error (Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (31.3))
I want to replace the firmware which is located at 0x00150000.
Please tell me the commands to install the firmware for this address
I understand Linux badly.

Hi @Alexandro 

Weclome to the Netgear community.  To know more about your case could you please tell us WNDAP320 is in standalone mode or managed by any controller? What is the current firmware version?

Thanks,

Managed by the controller. And most likely the wireless point began to be updated using the controller and there was a power outage at this moment. version was 3.7.9.0 - updated manually before failure

Hi @Alexandro 

Could you please let us know the model of controller and firmware version of the controller?

How many APs are in this state?

Is this issue you are seeing first time when you tries to manage ?

Is your WNAP320 running quite sometime and recently you are seeing this issue?

Thanks,

Raghu

Hi @RaghuHR 

controller WC7520  version 2.5.0.47

I started to configure it for the first time; for the first time we set up the controller and the wireless
and the only wireless failed
the rest of the wireless work is fine

I downloaded the firmware from the official site, pulled out the file with the firmware from the archive. It turned out to download this firmware to a wireless one using a COM port. to the address 0x80000000 via tftp protocol, then which command to enter in order for the firmware to be written or set to the address 0x00150000-0x00760000: "rootfs"?

There is no possibility to connect the wireless to the old controller, it burned out and cannot be restored
A new exactly the same controller was purchased, but the problem is that the wireless one does not work, I would like to restore it

[Alexandro]

Or I do not correctly understand how to restore wireless work. I would be very grateful if you help me

[Alexandro]

Can you tell me, is there exactly the same wireless, working, with what commands or how can I make a copy of the firmware and upload it to the non-working one?
