[tequila1981]

hi there
i have recently purchase an Arduino UNO WIFI board, i am experiencing an issue for upgrading the firmware. The board works fine with the traditional ardunio sketches(blink sketch), even after the firmware upgrade failure. I was following the tutorial (https://github.com/jandrassy/UnoWiFiDev ... k-firmware) on how to upgrade the firmware the error is experienced. Please see the attached file for the error. Can someone assist me on why i am receiving the error. My using a Window 7 PC and upgrading the firmware with the download tool v3.6.6.2
