Hey Rashad,
Are you using a USB to serial convertor in between or so.....
Are you sure that P0.14 is pulled low so that you enter the bootloader?
You can also try to set the UART baud rate to a low value like 9600.
Your power supply connections are fine.
Check this guide to see is you have missed any step.

I'm not sure what you mean , the developer of the programmer has marked the transmit pin as Rx because it should be connected to the mcu Rx and he has marked the receive pin as Tx because it should be connected to the mcu Tx, are you suggesting the user to connect them otherwise in this specific case?
Is the manual wrong?
Do not know if the manual is right or wrong, I know.
Lpc214x Rx pin is connected to the TX pin of the FTDI.
LPC214x Rx pin to pin TX of the FTDI.
The DTR pin of the FTDI RST operates THROUGH THE 74125.
The RTS pin of the FTDI operates the P0.14 pin THROUGH 74125
if this is true and everything is ok and in spite of that does not work look no problems with connections possible maybe in flash program settings, baud rates, serial set up, handling the serial port DTR and RTS pins must be to so SPI etc etc.
I talked to manufacturer for this issue and I came across that ,manufacturer has already made a cross connection means he has WRITTEN RxD OF FTDI as TX on connector and TXD as RX on connector , for easy connection to programming header on ARM board.
Now I can flash the code
here manufacturer should clarify these things that he has connected already crossed, so user will not get confused , any way its working now
You mean that up until now it wasn't working because you were crossing the programmer outputs (Tx->Rx and Tx->Rx)?
I think the manufactures is not to blame as the manual is crystal clear, the image I have posted in post #9 is from the manual and describes clearly the connection scheme that the user should apply.
is very clear that the manufacturer is correct and it is clear what he wrote.
"But," There customary rules
And we all know also that we usually connect the RX signal to TX and vice versa, but there are some that do different things. I do not know what are the reasons or where the benefits.
For it is clear that if we do things in what common sense suggests we tend to simplify the understanding and the
