C9120AXI U-boot issue

[Kalin Hristov]

Hello,

One of my home APs stopped working after being reset via the button

Here is the log:

U-Boot 2017.09 (May 21 2020 - 19:22:05 -0700) Broadcom BCM49408

Board: VANC-i

*** Board is not initialized properly ***

Uncorrectable ECC Error: intr 0x50, addr=0x0, blk=0,

Uncorrectable ECC Error: intr 0x50, addr=0x1000, blk=0,

Uncorrectable ECC Error: intr 0x50, addr=0x2000, blk=0,

Uncorrectable ECC Error: intr 0x50, addr=0x3000, blk=0,

There errros continue then it asks me to select board type partitions types and 

nand0: MTD Erase failure: -5

After that it reboots and the errors the same..

This seems like corrupted U-boot NVRAM.

As this is my home AP and does not have warranty can  someone please provide the SPI flash image via U-boot dump, so I can reprogram the flash and try to fix it. If someone can help it would be gladly appreciated as this is used at home and does not have warranty and I don't want to throw away so good and expensive device.

Thank You

I want to return to my original reuqest, please can someone provide an image of the SPI flash of the device, where the CFE and the second stage U-boot loader resides?

thanks Kalin. I purchased the access points through EBAY and CISCO express and the ap's are still in LLHW till 2027 however CISCO is not replacing asking for authentication of customer name on which these devices were registered. I do not who was the customer purchased these devices and I purchased from EBAY and I have all the valid purchase proof but CISCO is not accepting. I tried this LLHW, I told them its under life time limited warrenty. any help to change the ownership of the device? the EBAY seller is not changing the names.
