TFTP problem with Nick Gammon bootloader on mega 2560

koal01:
In the monitor after having inserted Serial.println(status) i can see the dynamic ip, nothing else.

There is no OK

nothing after Upload to IP?
did you upload the modified version over USB?

The modified version ? i flashed the mega with OTEthernet.ino after i modified the version in WiFiOTA.cpp
and no OK in the monitor just the Ip address

WiFiOTA.cpp is located in C:\Program Files (x86)\Arduino\libraries\ArduinoOTA-master\src
an OTeternet is located in C:\Program Files (x86)\Arduino\hardware\my_boards-master\avr

the network upload finished in console and no status is printed in Serial Monitor?

btw: the ArduinoOTA library is in Library Manager and I would remove -master from folder names

Yes i open the serial monitor after having flashed the mega via USB and it displays the IP but no OK

What do you mean by Library Manager ?
There are two library folders, one in c:\users\me\documents\library and the second one is the library i mentionned C:\Program Files (x86)\Arduino\libraries\

in IDE menu Tools > Manage Libraries
