I have a custom board I designed and had the PCB made for It is using the ATMEGA328P-AU with 16MHz Crystal and the FTDI FT230XS.
I have flashed the boot-loader and a blank sketch via ICSP. However when I plug the board into USB it is recognized as Basic UART on COM16 however, if I try to upload a sketch via USB I get programmer not responding. Go back to ICSP and it upload the sketch just fine. I have tried selecting Arduino Nano, Arduino Uno, Pro / Pro Mini and even MiniCore (setting the chip and clock) but I still get Programmer not responding. any Idea's? I have tried powering it by putting 10v into the onboard External supply that goes to a SN7805D and Powering it just via USB Still same Error. Tried chnaging USB ports, COm ports and even computers. Any idea's here?
