arduino broke again

i bought an arduino a month ago i got an error message so i posted a forum topic about it that can be seen here nothing helped so i sent support@arduino.cc an email i tried what he said but that didn't work so i emailed him back and i haven't heard back so i bought another arduino it worked then it stopped working and i got this error message

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

i just reloaded the firmware for the 8u2 and it still doesn’t work

Enable "Show verbose output during compilation" in File>Preferences.
Do you have the right COM port chosen?
Does the Arduino show up in Device Manager?
Try the loopback test.http://forum.arduino.cc/index.php?topic=73748.0

Isaac96:

  1. Enable "Show verbose output during compilation" in File>Preferences.
  2. Do you have the right COM port chosen?
  3. Does the Arduino show up in Device Manager?
  4. Try the loopback test.Loop-Back Test Instructions - Installation & Troubleshooting - Arduino Forum

  1. yes it shows a check mark next to COM& (arduino uno)

  2. yes it does

  3. nothing echos back

Make sure you have the loopback test correct. Could you post a pic of your setup?

Here it is

Here is the arduino

Well, the loopback test is supposed to be done with nothing connected to the Arduino. Disconnect everything, short RESET to ground, short the RX and TX pins, and try again.

oh sorry i thought you wanted a picture with the stepper motors and the driver in too
i did the loopback test with nothing connected

Well, if the loopback test isn’t working, that means your USB-to-serial chip is broken. Did you try the loopback test with the serial monitor or with something else? If you don’t already have PuTTY, I have attached it.

PuTTY.zip (259 KB)

yes i used the serial monitor that is in the ide under "tools"
what does PuTTY do?

Just ignore it. It was in case you didn't have a terminal application(stupid mistake)
If the port is showing up but it is not echoing anything back, again, make sure you have the right port chosen, and maybe temporarily remove the ATMega. Try it again.

this is my first arduino project so sorry i don't know what you mean by ATMega

Atmega328P-PU (aka ATMega, aka '328P) is the 28-pin chip on the board.

my arduino is an smd
i have another non smd arduino but i would rather use the smd because it is glued on to my project

(don't worry i put some rubber between the arduino and the metal)

has anyone looked into this???
