Boot problem on Tektronix TDS7404 scope? (Solved)

[xiang_zhen]

Hi,  I have swaped out the DS1245, but the issue is still open, there are two issue, one is

nvfs: STATUS: Mounting existing NVRAM file system
tcsTableUnpack: checksum failed on buffer
tcsTableLoadFromNVRAM: tcsTableUnpack failed

the other is:

    TmgrInit("/db")
0x16975c0 (tShell): Assertion failed: status == EXIT_SUCCESS, file ../src/dbmsInterfaceLibrary.cpp, line 149

which should be s.w issue, h.w should be ok, but we don't know how to fix it.

 I removed the # which was before  the NvramClearDb = 1 command inside the topscript and rebooted the scope. Afterwards waiting for a while it seems that the scope hangs at the tektronix logo  After connecting a terminal to the debug port it seem's that the vxWorks is booting but when executing the topscript.hw script,it halt on command "TmgrInit("/db")", same as below.

      TmgrInit("/db")
0x16975c0 (tShell): Assertion failed: status == EXIT_SUCCESS, file ../src/dbmsInterfaceLibrary.cpp, line 149

    please could you help to check and advise, I really have no idea, thanks very much.

Hello everyone,

I'm trying to dump the contents of my NVRAM so that I can save whatever is on there in case I need it going forward. Unfortunately, my TDS 7404 came without a HDD, so I don't have a backup copy of the NVRAM contents.

I'm trying to run @WORP3's code, but it doesn't seem to be working. I do have the files copied to the correct directory, and I made sure not to open them with Notepad. The 7404's terminal doesn't seem to be accepting my commands -- it just spits them back out at me. Maybe someone can give me insight as to what's happening here and if it's fixable without resetting the NVRAM.

I attached a picture as well, so you can see that I'm entering the commands and they're being returned. Apologies if I'm doing something really stupid -- I'm an analog electronics guy with very little understanding of this type of thing.

hi yes it works great look in your vxboot for a nvrdump.bin

i guees you created a custom topscript.hw  like:

Code: [Select]

################### topScript starts ###############################

 

    cd "pc:c:/vxBoot"


after booted type the commandline < NVRAMToFile.txt
