[SOLVED] FTDI and Atmega328P Error

Other Hardware 3rd Party Boards

Hi,
I want to upload a sketch to an atmega328P-Au with an FTDI but for some reason I get the following avrdude: stk500_getsync(): not in sync: resp=0x30

I have made the following connections
Arduino Uno slave Atmega328P-AU

  1. +5V +5V
  2. GND GND
  3. pin 13 SCK
  4. pin 12 MISO
  5. pin 11 MOSI
  6. pin 10 RESET
  7. pin 7 LED-HEARTBEAT
  8. pin 6 LED-ERROR
  9. pin 5 LED-PROGRAMMING
    0.1uF cap from VCC to GND
    0.1uF cap from AVCC to GND
    0.1uF cap from AREF to GND
    16MHz Crystal from XTAL1 to XTAL2
    18-22pf cap from XTAL1 to GND
    18-22pf cap from XTAL2 to GND
    10K resistor from VCC to RESET

Any ideas about this ? The board selected is Arduino Uno, the serial port is the correct one and the driver is also installed.

Thanks in advance,
Alex

You are carefully following Nick's instructions?

Okay after adding a 1uF cap, a 10K resistor and a lot of pressure to the chip I was able to successfully upload a sketch !!!

Thanks for the hint !
