Arduino Mega 2560 Failture?????

Using Arduino IDE 1.x

Hi, I'm using google translator apology but only speak Spanish.

I have a problem with the Arduino Mega 2560 (AT2560 16AU)

the problem is when I connect the Arduino Mega to a port (which always and connected and works corretamente, look at the silver single LED lights Power and L but the TX and RX not flashing as they always do and to compile a code out this error message ..

El Sketch usa 6.834 bytes (2%) del espacio de almacenamiento de programa. El máximo es 253.952 bytes.
Las variables Globales usan 819 bytes (9%) de la memoria dinámica, dejando 7.373 bytes para las variables locales. El máximo es 8.192 bytes.

help Me please

Do you have three exclaimation points in a row in a string in the program? There's a bug in old versions of the bootloader that chokes if it sees three exclamation points in a row. The bug was long since fixed, but lots of clones ship with bootloaders effected by that bug. (ex, Serial.println("Hello World!!!"); would trigger the bug. Serial.println("Hello World!!"); would not)

(note - it could be many things that are causing it, not just this. The signature of this is the upload proceeding part of the way and then choking in the middle - but you can't tell if that's what happened from looking at the error after the fact)

In my code does not ("!!!")

not this going on, the computer correctly recognizes everything is correct drivers, board, USB cable

Someone else has an idea how to fix it? I do not have money to buy another Arduino Mega :frowning:

Have you performed the loop back test?
-> This tests USB to Serial communication

If works, then,
Are you able to upload the "Blink" sketch?
-> If so, then it could be something code related.

If Blink upload fails, but loop back passes, then it is likely your bootloader is corrupted.
