Ive burned the bootloader to a new atmega328 and have the bare minimum setup on a breadboard to be able to talk to it from the Arduino IDE. I figured I would try something new and use the FTDI Friend to program the chip, but every time I go to upload I get the same error: avrdude: stk500_recv(): programmer is not responding.
The board is selected as Uno, and I've tried every type of programmer it lists. I've installed the latest FTDI driver (OS X) and tried a few different hookups and i still receive the same error.
Has anyone else run in to this?

Re: FTDI Friend Error with Atmega328
Which bootloader did you burn to the chip?
Do you know that your bootloader is active during the upload attempt? Do you have an auto-reset circuit or are you resetting manually?

I burned the generic bootloader that comes with the Arduino IDE. I've also built in an auto-reset circuit with a 1k from pin 1 to +5 and 1u cap going to the 328 pin 1. Ive also tried with the FTDI friend with the standard CST and changed it over to DTR.

Re: FTDI Friend Error with Atmega328
Do you have any leds hooked up to verify that it is resetting and the bootloader is running?

The only LED i have hooked up is to pin 13, running a basic blink sketch. The LED goes out and flickers for a short period and then starts blinking again after the failure.

Re: FTDI Friend Error with Atmega328
The bootloader should give you three short flashes after a reset. This indicates that it is ready for an upload. If your auto-reset circuit is working, the flash pattern should be the same if for a manual reset.
You can also try doing a manual reset just as the upload starts. You need to time it right, so it may take several tries.

Re: FTDI Friend Error with Atmega328
Found the issue... I was using the wrong size cap. However a manual reset seems to work perfectly so until .1uf caps come this will work. THanks for your help!
