I'm having trouble uploading basic sample sketches to my arduino Lilypad. It takes a really long time to upload (1-3 minutes) after compiling. The IDE shows that the sketch has been uploaded, however, the console shows nothing. Everytime I plug in my board, the light keeps blinking, but nothing else happens.

After failing to see any sample sketch working, I tried with this simple test, and it still didn't work.

void setup() {
    Serial.begin(9600);
}

void loop() {
    Serial.println(1);
}

So far I've checked the port, that the right board is selected and I've installed the latest drivers for my FTDI conversor (mini usb to TTL FTDI FT232RL). These are the error mesagges:

And so on.

Any ideas? Thanks for your help.

I would suspect a corrupted bootloader is affecting the communications with your Lillypad (ATMEGA328P). You could try reprogramming the bootloader using another Arduino as ISP connecting it to the pins according to this image:

Lilypad ICSP port

As it was already reported in other forums, there are some counterfeit boards on the market. If that is not the case, it is not uncommon for the bootloader to get corrupted if the board is mishandled when powered-up or if you look at it when it's not in the mood ( :P ).

Try to follow the steps from this guide in order to reload the bootloader.

Another option is to use an USBasp like this and burn the bootloader as it is explained here
