    other times uploading HEX fiel gives:

    avrdude.exe: AVR device initialized and ready to accept instructions

    Reading | | 0% 0.00s avrdude.exe: arduino_read_sig_bytes(): (a) protocol error, expect=0x10, resp=0x90 avrdude.exe: error reading signature data for part “ATMEGA328P”, rc=-3 avrdude.exe: error reading signature data, rc=-1

    the response is always the same: resp=0x90 what should it be?

    thanks to all kind of help

    dear all, I have a lot of problem with this demo board: - serial connection won’t work properly: seems that the board TX data at 57600, 7,N,1 but it accept command at 8,N,1! So command “R 00” return “Invalid Command” - if I reply in 8N1, it responds, but it’s almost unreadable: “Reg. Addòå󳺠Š¢µ·ž®±´½±ž±™…„ž” the board seems to be BROKEN !!!!

    So I decided to upload the HEX file. but upload won’t work, too: it stops each time in different position. SEEMS ARDUINO BOOTLOADER NOT PRESENT! But I am new with arduino. Should it be?
