I recently bought an Arduino Pro Mini(3.3V 328p, 8MHz) along with a CP2102 USB to TTL UART convertor. When I try to upload a sketch to the Pro Mini using it, I get a avrdude:stk500_recv(): programmer is not responding
error. My connection was like
Arduino pro mini CP2102
TXO ----------------------------> TXD
RXI ----------------------------> RXD
VCC ----------------------------> 3V3
GND ----------------------------> GND
DTR ----------------------------> DTR
I tried inter-connecting the TXO and RXI pins and had no luck. Also pressing and releasing the reset button on the Pro Mini doesn't seem to work either. I also tried programming it with my Arduino Uno, by removing the 328 and connecting correspondingly. Still no use.
Does any one have any ideas?
