HP 54522A Firmware Re-flash Error

 

Hi,

I'm getting an error when I try to re-flash the firmware from disk on my HP 54522A oscilloscope that I purchased a year ago. The scope has been working fine for a year and started giving me trouble during the boot up check. I replaced the lithium nonvolatile ram battery and while trying to re-flash the latest firmware from the disk, I get an error during the update. The ROM image flashes successfully but after the re-flash of the System image I receive the following Message stating "Updating From File: System Failed: 4, 15, 38982". I'm wondering if this is indicating a bad flash Rom IC. Any help would be appreciated. Note: The disk read of the System image file reads successfully during the re-flash but fails on the writing to the Flash Rom (Attached picture shows error results).

Thanks in advance

So I ordered some N28F010 150 Intel Flash Memory IC's from Ebay and will be attempting to replace the 1st Flash IC to see if this solves the issue. I'm assuming that the error is indicating the memory location of the failed flash writing to be the 1st Flash IC. There are 8 of these Flash chips on the board so I will replace this one and hope it takes care of my problem. I can't find any memory mapping documents for this board so hopefully my assumption is correct on this issue. Sure wish there was a schematic for this HP oscilloscope. Would make troubleshooting so much easier. I've searched everywhere and no luck finding any additional info except for the service manual that doesn't tell me what I need to know. Will post my findings to let others know if this takes care of this problem.
