I'm having trouble uploading a sketch on my Pro mini AT328 5V 16 MHZ that I got from SparkFun.
I'm using an FTDI TTL-232R-5V-WE cable that supplies 5V. I have wired it up as follows: green - green yellow - TX0 orange - RXI red - VCC brown - GND black - BLK
If i try to upload in "verbose" mode by holding down the shift key then pressing upload i get this: avrdude: usbdev_open(): did not find any USB device "usb" If I do it in normal mode I get this: avrdude: stk500_getsync(): not in sync: resp=0x00
I have tried pressing the reset button at various times.
I have done the loopback test posted at the top of this forum, that FAILED. However I have also done my own loopback test by jumping TX and RX and CTS and RTS, that PASSED. I don't know what this means.
I have set the "set RTS on close" in the advanced settings on the COM port.
I have verified the Board setting in the IDE. I have tried Pro mini / pro at328 5v 16mhz as well as what was suggested in the troubleshooting guide of using Duemilnove at328.
I have verified the com port is correct in the IDE setup
I have Verified the drivers are up to date for the FTDI cable-at least according to Windows 8.1 - Does 8.1 suffer from the same ailments as Win7?
I have tried two different Pro Mini's and one of my Pro's
All three seem to have a bootloader installed because I do get a blink on the LED when I press the reset button. They came from SparkFun if that makes any difference?
I have tried most of the above on my windows XP machine as well with the same results.
I don't know what else to try. Any Ideas?
