How to download the mtd block via TFTP?

[A.W.C.]

There is no way to update Busybox to latest version, I can only use existing version, the code is precompiled and running on embedded device.
Regards,A.

 Version 1.4 is seriously outdated.
please try the latest version. You are missing several fixes from the last years.

note: there is no need to replace BB completely. you can create tftp only and see
what is happening. Do not use links otherwise you may accidentally overwrite your
current binary.
