I recently bought a FTDI to serial adapter on amazon about a week ago. And it worked fine for a day when uploading some test code to my Arduino Pro Mini but then I kept on getting the error message - Upload error: Failed uploading: uploading error: exit status 1. The board connects fine to my computer, but the Arduino Pro Mini has trouble staying in the correct position to get the code uploaded. Anyone have any suggestions on how to keep the Pro Mini in place with The FTDI adapter? And how to fix the Error?
If you cannot hold the Pro Mini stable then solder a header to the Pro Mini.
Also cross-check using another FTDI and Arduino. Some China products tend to fail very soon.
