Altera DE-10-Nano UART Rx and Tx in Pin Planner

Hi Iggy,

Looks like you found some special software tool developed by Terasic to deal with pin assignment issue.

• FYI... this is Intel FPGA forum. Perhaps it's better if you check with Terasic directly since you are using their board and also their software tool
• You can contact Terasic support via support@terasic.com

But even if I look at the terasic software screen shot, it only assign IO standard to UART pins but not the actual pin location itself. So, maybe you don't need to assign the pin location after all. You can check Quartus fitter report later to verify whether UART pins is auto assigned to correct pin location or not.

Also like I said, make sure you have configured the IO pin mux setting correctly in HPS IP as these are multiple function IO pins.

Thanks.
