unable to upload new file to tftp server

unable to upload new file to tftp server

[Toews, Dietrich]

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

Could you retry with current master? There have been some changes
recently.

Hi, Sascha,

I did not see the changes in master.
So I made the same patch and it works.

Thank you!
