I'm having a problem linking a Xino to FTDI adapter to a USB to TTL.
I have connected them as follows -
XINO adapter USB-TTL
GND GND
CTS
VCC 5V
TX RXD
RX TXD
DTR RST
When I tried to upload a sketch, I get the following-
avrdude: stk500_getsync(): not in sync: resp=0x00
Any ideas would be appreciated
Thanks
Ideas anyone?
Does the baud rate match the bootloader's baud rate?
Yes they match
Hi i have the same problem
Did you find a solution ?
2 things spring to mind, is the usb-ttl adapter real ftdi or cp2102, i have cp2102 and the reset pin on it is to reset the adapter not the arduino, also the pins on my adapter are labeled tx connect to tx and rx to rx, stupid i know.
one simple way to test the adapter is to short tx & rx together open a terminal on your puter and see if anything comes back when you type
I have a sparkfun ftdi basic adapter.
Il tried to plug tx and rx together and i see what i type in the terminal.
Is the 100nF on RST mandatory ?
I finally found that the problem was me ! 
I chose the wrong board on arduino ide
