Appendix B
For download operations, ensure that the permissions on the file are set correctly. The permission
on the file should be world-read.
Before uploading the image file, you might need to create an empty file on the TFTP server. To
create an empty file, enter the touch filename command, where filename is the name of the file you
will use when uploading the image to the server.
During upload operations, if you are overwriting an existing file (including an empty file, if you had
to create one) on the server, ensure that the permissions on the file are set correctly. Permissions on
the file should be world-write.
