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
2. USB zu TTL Device with CP2102 http://www.amazon.de/gp/product/B00AFRXKFU?refRID=46Z2KPKY27M66WD7V4C9&ref_=pd_cart_vw_1_1_p
I just downloaded version 1.6.7 (tried 1.6.6 yesterday) from here and installed it completely default.
Version 126.96.36.199, 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)
and I definitely set the correct COM Port, switched it to another number and so on... nothing helps.
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...
