I have a programmed AtMega328P removed from a UNO board and in good working condition.
The pcb is done and all basics have been checked.
Trying to download sketch from IDE using a FTDI 232 - USB (5V).
Power supply to pin 7 reads 5.1V with reference to pin 8.
Reset pin 1 is pulled up to Vcc via 10K and also connected to the DTR pin via a 0.1MFD + 1K resistor to GND .
Rest TXD, RXD, 5V and GND are all connected as they should..
Apart from above the Crystal is 16MHz with two 22pf capacitors.
The problem : When connected to IDE the port is identified but the download process halts with following error :
avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xbe
( I can see the DTR pin going low to start the download process )
SO where do you think the possible hiccup is ??
