What is needed for FTDI

Projects Programming
1

Hey guys,
Just bought a USB FTDI programming board. Having some issues with programming my arduino mini. AVRDude
Below is how I have it connect.
FTDI Board - Mini
GND - GND
CTS - GND
VCC - VCC
TX - RX1
RX -TX0
DTR - DTR

I am running on Windows 8.1 using Arduino version 1.0.5,
Com Driver is CDM 10.00(the latest from FTDIChip.com)I have the set the com port to 7 and check the "Set RTS on Close"
I have Pro Mini 328 5V selected. I am unsure of what programmer to select I do not have an option for FTDI

I am getting avrdude: stk500_getsync(): not in sync: resp=0x00 as my error which I believe is communication error.

Please help
Thanks

Does your mini have power ? (did you solder the pads from the middle pad to +5v on the bottom of the FTDI BD ?)

TX - RX1
RX -TX0
DTR - DTR

Would it not be a good idea to use the same port on transmitt and recieve?

Also check that the TX and RX are both the same way round on both devices. On some devices TX is an input and RX is an output. It depends on how the equipment is classe, as DTE or CTE.

Is this a clone?

Selecting "programmer" is for connecting an AVR ISP to the SPI interface pins (SCK, MISO, MOSI, Reset, Vcc, Gnd). It is not applicable to the USB/Serial adapter.

I am assuming Arduino does have power the LED is lit; The middle pad and +5v are now solder together. I was able to program the mini using an Arduino Mega but now I am using the Mega for a permanent project and thats why I bought the FTDI programmer. More than likely the FTDI programmer is a clone.

Using a meter I verified TX pin to TX on the IC and the same for RX. I check both on the FTDI chip and the atmega328.

"FTDI programmer" not a programmer - just a USB/Serial adapter.
USB serial goes in, is transferred to bootloader via the uC serial port.
Bootloader responds, goes out to PC.

There is a bootloader installed on the chip, yes?

My old sketch is still running so I am assuming the bootloader is still on there. I tried another mini that I have successfully programmed via ISP and receive the same error. I read that the FTDI might be flashed with the wrong settings so I downloaded Mprog and reflashed the eeprom with the default settings. then I read and parsed to verify everything was successful. I've also tried re installing the drivers several times.

I have a 3RD pro mini that programmed successfully and was able to repeat the outcome. I am still unsure what is the issue is with the other two. Might be a poor connection with the header. Thank you everyone for the help.
