Arduino Pro min can't load a sketch

Using Arduino IDE 1.x
1

I put the bootloader on the Arduino PRO mini using a Arduino UNO and the green light is blinking.

I used a uart bridge with my PC and I try to upload a sketch, I get :

-> avrdude-original: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00

I went back to arduino and reburn the bootloader and here the output. It seam fine to me.

So I works with the arduino but not with the UART bridge. What I'm my missing.

Arduino UNO is connect to pro mini as below when I burn the bootloader --- on the chip it it "mega328p-au 1533"
11 to 11, 12 to 12, 13 to 13, 10 to rst, 3.3 to vcc and GND to GND.

When I try with UART bridge, it's connected this way:
DST - RST, 3.3V - VCC, GND -GND, TX - RX, RX -TX.

Do you need a programmer all the time connected to the pro mini to program it, What I'm I missing????
Help!!!!!!!!

What is the UART bridge? These signals look odd: DST - RST
Maybe disconnect that, and press Reset on the Promini when the IDE shows "Compiled xxx of 32xxx bytes".
Can be easier to get the timing of the reset press if you select File:Preferences and turn on verbose outouts.

This is what I'm taking about, might call it the wraong way.

And here the arduino i'm trying to get to cooperate.

I can't open e-bay links (blocked). Does that unit have DTR at one of the headers, or available on a pin somewhere? Many have the chips Reset input pin brought out, which does no good at all.
If DTR is not brought out, you can cut the trace that brings Reset to a header and add a wire from the DTR pin on the chip to the header so it can be used to reset the 328P.
Looks like pin 28 if this is the same chip.

You can get those elsewhere in CA for much less:

Do a search on ebay with this, first item.

It's working... The GRN I thought it was Ground. Why they didn't call it RST or just plain RESET.... What dose it stand for GRN, green? Anyways.... So I reconnect everything the way you said and change to 57600 baud and "ET VOILA".... I'm sure I already try this but... I tried again on RPI with the usb and it's work... So in turn I tried with the UART port and what do you know it works... At first it didn't because I had my reset in the wrong GPIO but in the end it work.

The combination of wiring being wrong and baud rate being set to low cause all my problem. So here how it plug.
In any case, baudrate at 57600
FTDI -> Arduino Pro Mini prog header

DTR -> GRN (Reset)
RX -> TX
TX -> RX
3V3 ->VCC
GND->GND

This is how it's plug via the RPI
RPI -> Arduino Pro Mini prog header

GPIO 16 -> GRN (Reset)
UART RX -> TX
UART TX -> RX
GPIO 1 3V3 ->VCC
GPIO 39 GND->GND

Autoreset file for rpi:

#!/usr/bin/python

fd = sys.stdin.fileno()
fl = fcntl.fcntl(fd, fcntl.F_GETFL)

GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
dtr = re.compile('.+TIOCM_DTR.+')
start = time.time()
pin = 16
