I run the boot loader example according to the document "AN4367".The boot loader example is based on FNET stack.
The PC pings the MCU successfully.The MCU always shows that "TFTP Error: Code 0 "Connection failed" when running the command "tftp".
I use the tool "wireshark" to capture the Ethernet data. The tool does not find the "tftp" request that is based on UDP protocol.
Can you help me find out the problem?
