Problems using new ATMEGA328p-PU in my Freetronics Eleven Board (Uno Compatible)

Question

Hi,

I am an absolute beginner and I am having trouble uploading to a new chip in my Uno compatible board.

I purchased a freetronics beginners kit which came with an Uno compatible board (link below).

Eleven (100% Arduino Uno Compatible) | Freetronics

I also purchased a bunch of ATMea328P-PU chips from ebay described as 10pcs New ATMEGA328P-PUATMEGA328P-PU Microcontrolle r With ARDUINO UNO R3 Bootloader IC Chip (Link: 10pcs NEW ATMEGA328P PU Microcontroller With Arduino UNO R3 Bootloader IC Chip | eBay).

What i was hoping to do is use the freetronics board to upload sketches to the new chips and then embed them directly into some projects i want to make (led parking sensors and water tank level sensors).

I was thinking that because the listing said the chips have bootloaders installed i could take out the ATMega in my board, replace it with the new chip, upload the sketch and take the chip back out. Have i missed vital steps (e.g. an external programmer or something)?

When i tried this I kept getting errors that say:

avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xb0

this repeats 10 times and then says

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

If i take out the ne chip and put the original back in it works fine and uploads as normal.

Any advice would be greatly appreciated.

Mine too, just because of the not in synch message frequently depends on wrong settings of the CPU. The better solution is to use any arduino-like compatible to re-upload the bootloader on the chip. Enrico

Hi Jessica,

I have looked at the schematics of the Arduino Uno and the Freetronics Eleven and I can see no obvious reason that it isn't working. If you have access to or can borrow a genuine UNO I would try the chip swap again to see if the chips you bought work with the UNO. You could even try putting the UNOs chip into your Eleven to verify that it works. It is always possible that your ebay chips don't really have the bootloader or they got a bad load. You could also try searching for the error messages you received on the Arduino Site to see if they have any further suggestions.
