Error Using NCM: Frimware Upgrades

so by chance, where is the TFTP root directory pointing to for your TFTP server? if you are using the built-in SW TFTP server the default location should be something like "C:\TFTP-Root"

I've seen this issue come up because part of the job is to copy the firmware from the repository to the root directory for the TFTP server, and that function was failing. We corrected it by repairing the core services, completing the config wiz, and restarting the box.

I'd verify that the permissions for the TFTP root directory all check out, for troubleshooting purposes you may wanna just give "Everyone" read/write" access. If it's still failing try repairing the core services.

By default that TFTP root Directory should be empty and NCM transfers files in and out of it as needed, so it sounds like that bit may not be working correctly for you right now.

Hello.

Have the same problem.

""Everyone" read/write" access" - without effect.

Please help.

Thank you for replying christopher.t.jones123​. For some reason, I thought I replied earlier, but the message didn't post, it was saved as a draft.

Yes, the TFTP directory is c:\tftp-root. I copied the files there myself. However, I think back-then, the tftp target directory had been changed by someone (perhaps me while I wasn't thinking about what I was doing) to the c:\sftp-root directory. Anyway, I do sometimes experience the problem when the file is in the wrong directory.

rusfatman​, please check:

     1. The file is in the c:\tftp-root directory.

     2. The TFTP program is configured to target the c:\tftp-root directory.

     3. All the APEs have the same file in the same place.

The NCM documentation specifically says not to use the default folders, yet the script pulls the FW from those locations by default. This was pretty confusing as I was setting this up.

So a little clarification on how the process works. When you kick off the firmware upgrade operation one of the first things is that it copies the firmware from the repository location into the TFTP or SFTP root location, and that's where the device downloads it from, then it removes the image from the root location after it is done.

If you are having issues with firmware transferring to the device cause it can't find the file in the root location, I would recommend investigating why that underlying task of copying it from the repo to the root location is not happening correctly.

I believe the reason they don't want you using the root location as repo location is it can mess with some of those underlying tasks

I just ran into this issue the other day.  I had the image file in the SFTP-Root folder.  After removing it the upgrade took place as expected.

The mechanism still seems a little strange though.  Doesn't it imply that you cannot do multiple simultaneous upgrades?  (Since it would start one upgrade and then the image would be there so any subsequent job would fail until the first finished).

If you wanted to know more about how NCM do the firmware upgrade you can, enable the session trace log.

It will generate logs how NCM takes place the firmware upgrade.

Also here some documentations for reference:
