Audi McAvoy / Mbed 2 deprecated FRDM_K64F-TFTP

Super lightweight, not at all robust, TFTP server for FRDM-K64F eval board.

Dependencies:   EthernetInterface mbed-rtos mbed

Fork of FRDM_K64F-Ethernet by Rangel Alvarado

Super lightweight, not at all robust, TFTP server for FRDM-K64F eval board. This tool supports read-only access to two files. It does not support NACK responses or timeouts. The tool is intended for use by our test department to check out Ethernet functionality on our main processor board.
