I was able to download the bootloader to my robostix and verify it from the flash.
Now my problem is that I am no longer using the AVRISP cable. I have moved to the UART cable which has a FT232R Breakout board to my USB port. AVR Studio can't connect any longer to the Robostix.
My settings are to connect via STK500 or AVRISP and auto detect the COM port.
No response from the board. I wonder how I can download a program via UART to Robostix now that I have the bootloader there.
I used my voltmeter to measure the voltage across the +V and GND on the UART of the Robostix and no voltage registered. Does the UART get power from the laptop USB or from the Robostix power supply? Or do you supply a separate power to the FT232R breakout board? I measured the voltage across the breakout board and there also no voltage. Is it possible my UART cable has bad wiring?
According to this tutorial I don't use AVRStudio to download via UART cable?
