firmware disaster

Recently tried reuploading firmware onto my arduino, since I had to modify it to accommodate an additional fan port..... [www.geeetech.com]

Before adding the extender and reuploading the firmware, everything worked fine. Now, when I try to upload, it gives me the following error:



Binary sketch size: 53,108 bytes (of a 258,048 byte maximum)
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer




It compiles fine, but then will not upload or something. I am new to this so any help is greatly appreciated! Thanks.

Are u really using an stk500 to program the arduino... I doubt it. Looms like some setting is amiss telling avrdude that youre using stk500. that is a development board for avr devices by atmel. Yes you could use stk5p0 to program an arduino but not sure why you would...

Do you have any printer host software running? I also wasn't able to upload to my board, before realizing that my printer was still connected to Repetier Host.

The Arduino IDE isn't connecting. That's what the error message means. Could be something as easy as you have another port connected to the board or not having the right port selected in the Arduino IDE selected. Worst case something has happened and the Arduino has failed.

Quit any apps that may be using that port, like your printer host software, make sure the Arduino IDE has the right port displayed and available and try again.
