[U-Boot] tftp command return value

[l3iggs .]

Hello,

I'd like to test if a file  on my TFTP server exists. I would expect that using 'if tftp filename.ext; then echo exists; else echo doesnt; fi' woudl work here. However, It always shows that the file exists. I expect that others want to do the same thing because grep -r "if tftp" include/configs/ gives 15 hists. 

'test -e tftp filename.ext` does not work either.

Does anyone have a solution for this?

Best,
