Application doesn't run on Colibri T20 256MB V1.2B

Hi
I managed to have a Colibri with our application working properly and created a backup.
Now I am trying to use the backup on other ones but I get this error:

What is the problem?
I tried on different Colibri modules but I get the same error.

Hi @shivaOD ,

The message in the log view panel says: “nvflash configuration file error: file not found” so i guess the .cfg files is missing or corrupt. Can you explain how you start the update tool? manually? or by auorun link/batch file? If by autrun, please provide details. most probably a file path error.

BTW: is the problem with USB solved?
