Subject: unable to upload new file to tftp server
Date: Mon, 10 Sep 2018 10:08:52 +0000 [thread overview]
Message-ID: <F272D9410BD38E429D604B94748C61547AB0D488@WIEMS02101.ceu.corp.heidelberg.com> (raw)
Hi,
when I try to upload a new file from barebox to an tftp server I always get the error: "Function not implemented".
When the file is existing on the server, there is no problem.
Prerequisites:
- mounted directory to an tftp-server
- test: cp local.file /mnt/tftp-dir/remote.file
Progress:
- first step of cp is to get the "stat" of the file - the answer of the tftp-server is ENOENT.
- then cp tries to open the file, but it does only add O_TRUNC when the file exists
- tftp_do_open returns ENOSYS when O_TRUNC is not set
So you can't upload a non-existing file, but in most cases one needs exactly that.
Dietrich
