Unable to upload to Arduino Pro Mini with FTDI

Development Boards Arduino
1

I have a couple Sparkfun Arduino Pro Minis and Sparkfun 3.3v FTDI Basic. I am unable to get programs to upload to the board with FTDI programmer.

avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x00

I have two of these boards and they both have the same issue. I have tried some other FTDI boards, but get the same problem with them. I can upload code via an Atmel ICE so it seems the processor is working fine. I have also reburned the bootloader several time with no luck. Every once in a while, I will get one script to upload, and then the problem comes back. Tried several cables plugged directly into the computer and not through a hub.

I’m ready to just throw everything away since I can’t get any work done this way. Any suggestions on what else to try?

Hello, so you got a pro mini 3.3V version, right? Have you installed the FTDI driver properly?

Yes. As I said in the original post, "Every once in a while, I will get one script to upload, and then the problem comes back. " I have ordered a couple more Arduino Pro Minis and will see if those will work.
