FWIW: I
had issues with TFTP timeout’s as well while
downloading . I found that the length error is not handled
correctly and I got timeouts (T) even when the data was
perfect. May not be the perfect solution or the correct
place to fix it for good, but it fixed my problem. I’m
downloading binary files up to more than 30MB without any
issues now.
