Hello, so I am able to burn the bootloader and upload the "ReadNetworkSettings" sketch using Serial USB Comm.

I am also able to ping the default IP when the Arduino is powered and connected (192.168.1.128)

Then I tried to upload the sample "blink" ( utilities\tests\blink\atmega328_blink9.bin ) by resetting the Arduino Board (LED13 now blinks quickly), then type "tftp -i 192.168.1.128 PUT atmega328_blink9.bin" (I already cd'd to the folder). After some times, it says "Connect request failed".

Previously, after uploading the sample "ReadNetworkSetting", the Arduino will be able to run the sketch after about 10 seconds after reset (the upload period).

But if I did attempt to TFTP the sketch (atmega328_blink9.bin), my Arduino is now not able to load the previous sketch and will keep blinking quickly (even after resetting, and waiting for 10 seconds). The previously uploaded sketch is now gone, but I am still able to upload sketches via serial. What should I do?.. (Windows 10 64bit, Arduino 1.6.7)

Hi, I have also had problems with the TFTP tool of Windows. Try it once http://tftpd32.jounin.net with the tool. And adjust or turn off the firewall.
