I had a look for similar post , but can't see one.
I built a minimal component board for a Atmega 328 MCU and fitted a 6 pin ICSP header for programming using a USBAsp. it worked , no problem. Then jsut for fun I tried programming my Eleven board with the USBAsp - again no problem, but when I tried to go back to the using the usual mini USB connector to upload sketches , I get "programmer not responding" message from the IDE. What have I broken and how do I fix it?
ICSP then no USB
Re: ICSP then no USB
When you upload sketches using the ICSP pins the Arduino bootloader is wiped from the microcontroller, as it isn't necessary - you're directly uploading the code to the MCU.
To get your Eleven back to normal, simply upload the bootloader to the Eleven using the Tools>Burn Bootloader option in the IDE, then upload your sketch as normal via the USB cable.

Sometimes life's like that

Re: ICSP then no USB
Ive got the same problem.
i can program with your USBASP but cant use the micro usb on the Eleven.
Any ideas??

Try reflashing the bootloader (connect USBasp to ICSP pins and use "Tools>Programmer>USBasp" in IDE then "Tools>Burn Bootloader".iSteve wrote:Ive got the same problem.
