Hello,
I am working on a design in which i need to connect my own uart (rx, tx) to the UART of the board. I've found on "Zedboard Hardware User's Guide" that the rx is on the C14 pin and the tx is on the D11 pin. I've connect my own uart to these pins like:
#### ucf file #####
NET "rx" LOC="C14"
NET "o" LOC="D11"
I got this error in the "place and route" phase:
ERROR:Pack:1107 - Pack was unable to combine the symbols listed below into a single IOB33 component because the site type selected is not compatible.
Summary:
Symbols involved:
BUF symbol "tx_o_OBUF" (Output Signal = tx_o)
PAD symbol "tx_o" (Pad Signal = tx_o)
Component type: IOB33
Site Location involved: D11
Site Type involved: IOPAD
Same error for the rx. I don't know how to resolve this problem. So could someone help me ?
Thank you,
Najem
