SEVENSTAX TFTP is an implementation of the Trivial File Transfer Protocol specially developed for use in embedded systems. TFTP is a particularly efficient transmission protocol for simple upload (e.g. firmware updates) and download (e.g. log data) of files. It deliberately avoids complex overhead such as rights management or file system navigation.

  • Trivial File Transfer Protocol according to RFC 1350
  • Client and server
  • Binary transfer mode
  • Packet sizes up to 512 bytes
  • Use of the standard UDP port 69
  • further UDP ports configurable

Suitable clients and servers are available in large numbers and are often already part of a PC operating system. As a command line application, you can use batch processes e.g. for automated firmware upload in production.
