I had a freaking 4 days now finding out what was going wrong while uploading sketches on Arduino Pro and Arduino Mini. Thanks to the net I found solutions, but unfortunately not all information in one place. This is why i thought i but this together in one post.

My Pro and Mini would terminate each attempt of uploading sketches with an error. The cause for this could only be wrong cabeling from FTDI to Arduino or missing bootloaders.

Therefore my first step has been to burn new bootloaders by turning an Arduino Uno into a bootloader:
 
Load Sketch ArduinoISP from Files/Examples on Arduino Uno
Uno         Arduino Pro/Mini
D11         D11
D12         D12
D13         D13
5 or 3.3V                   VCC
GND         GND
D10         RST
Select Arduino Pro or Mini according to what you are using  from Tools/Board
Select w/ Arduino as ISP from Tools/BurnBootloader
Off you go...

No the wireing for the uploading
The FTDI used is the UM232R. Same wiring possible with any FTDI Board

For 3.3V Boards
Arduino Mini/Pro 3.3V      FTDI
TX         RX (5)
RX          TX (1)
5/3.3V          3.3V (19)
GND          GND (24)
RST         DTR

Arduino Pro 5V      FTDI
TX         RX (5)
RX          TX (1)
5/3.3V          USB = 5V (14)
GND          GND (24)
RST         DTR


I did this with 4 different boards and it worked perfectly and smooth....Have fun
