I have a RISC-V design implemented on the Genesys2, with a UART that currently works through the USB-UART microUSB port, which just uses the uart_rx and uart_tx lines. I would like to send the UART output through the PmodBT2 to my Mac instead (connect via "screen" command in a terminal). From the Nexys 3 FPGA reference design, I believe I should connect the my uart_tx port to RXD pin on the PmodBT2, and uart_rx to TXD. I have done this and programmed the FPGA, and also established a connection to PmodBT2 from my Mac. However, when I run a hello world, I don't see any output in my terminal window. Do I need to do anything with the additional pins on the PmodBT2 (CTS, RTS, RST, STATUS), or change any settings on the PmodBT2 from the default? The Nexys3 FPGA reference design appears to set RST to 0 and CTS to 1--I tried this but did not see any change. I only want to send data from the Genesys2 to my Mac (one way traffic). Any help would be appreciated.
