Dear all

I still face the same issue

I added Signal tap to the design and tried to capture the signals but i see the CTS stays high and RTS stays low all the time

Will the UART transmission and reception works if i set the RTS and CTS signals in Sopc builder

I connected the CTS pin of FPGA to CTS pin of RS232 and RTS to RTS pin of RS232

Please give some idea to solve this problem

regards
