Occasional ContributorDE10-Nano 1 Mega Baud Serial Transmission using UART
Hello sir,
The UART IP cannot work alone, it should be connected to a processor or a custom logic that take care of the initialization and processing of the IP. I have attached a design example for you to show how to connect UART with Nios II processor. Furthermore, it has a piece of C code to initialize and run a communication stream between two UARTs on the same board.
Thank you,
Frequent ContributorHello,
This IP is used for connection with peripherals, like sensors. If you want to have it as external hardware UART connection, the FT232R hard chip should be helping you if you connect it with the two pins GPIO (TX & RX).
VROGE2But will that work on the DE10-nano SoC where the peripheral in question (UART) is located on the HPS rather than the FPGA? I understand how it would work on a board where the UART is located on the FPGA because the RX and TX pins can be mapped to the UART but when the UART is on the HPS I cannot directly map to those pins.

Hello,
This is valid for FPGA side only. If you want to use the UART of HPS, this requires a modification on board level to map the pins, i.e. it can be used only when you want to build your custom board.
Thank you
