Standard specifies no way to send arbitrary sized files in TFTP.

You have 2**16 segments, each 512B, totalling 32MB.

There is enchancement to TFTP increasing segment size, yet most common
method to workaround this limitation is to roll-over segment#, which is
not supported by standard .

You really should migrate to scp If not possible, just try another tftp
which supports segment# roll-over.
