after searching the Web for hours in hope to get it work I finally need to ask the community for support.
Hope you are able to help me in my somehow "easy" problem.
What I have:
ATmega Pro Mini / 3.3V, 8MHz / ATmega328 -> with preinstalled Bootloader and blinking when powered
USB zu TTL Device with CP2102
I just downloaded version 1.6.7 (tried 1.6.6 yesterday) from here and installed it completely default.
The CP2102 is recognized like that:
Version 22.214.171.124, all options on default.
I connected the Mini Pro & the Programmer like that:
but it doens't change anything if I switch TX & RX.
When I plug in my programmer, both, Arduino and Programmer fire up and show red lights, the Arduino starts to blink in ~1 s intervals, endless. ("Blink" might be preinstalled)
I just wanted to upload an empty sketch, my settings are:
and I definitely set the correct COM Port, switched it to another number and so on... nothing helps.
Upload with programmer always results in:
avrdude: usbdev_open(): did not find any USB device "usb"
no matter what I do, no matter which board or processor I choose.
Ideas? Due to DTR, a manually reset should not be required. Will I need to set specific COM port settings?
Thanks for any support... I tried it now with 3 PCs, 2x Win 10, 1x WIn7, all X64...
