Hello. I am going round and round in circles trying to program a Cyclone IV EP4CE6E22C8N on a mini board. I get the message:- "Error (169057): Can't place I/O pin clk at pin location 24 -- I/O pin uses weak pull-up, which is not supported by this pin location". My board has a 50Mhz clock at pin 24. If I set week pull-up off I get errors:- "Error (169187): Following feature(s) of I/O pin ~ALTERA_ASDO_DATA1~ has invalid setting(s) in the configuration scheme ACTIVE_SERIAL when the pin is placed at pin location 6 Info (169189): I/O feature 'Weak Pull Up' has an invalid setting. The setting should be ON." for four pins I am not using.
Did you set the ASMI (DCLK, ASDO, DATA0,nCSO) pins to use as regular IO in the Quartus II option? Go to Device and Pin option -->Dual-purpose pins then change to "Use as regular IO" for DCLK, ASDO, DATA0 and nCSO.
nysuf. Thank you...I've been searching for ages to find this setting option. Quartus is a great piece of software in what it does but there are so many options off so many menu choices it can be confusing to a noobie!! Thanks again.
