hi,

i am trying to do hello world program mentioned in below video..

https://www.youtube.com/watch?v=yetvltb4hm4

i am using cyclone 5 soc kit.

but i got a problem with rx and tx pin assignment..at 4.45 in video. i am using quartus prime 16.0. here the below mentioned pins are not assignable.

so i tried by assigning only clock, but in terminal after running program nothing is displaying. so i think its because of not assigning the pins for tx and rx. anybody know how to solve this problem ?

baudrate is 115200 for both uart ip and terminal. and i am using same package as mentioned in usermanual.

my doubt is hps pins are not assignable, so how to solve this problem?

the above one is from user manual of cyclone 5 sockit .(you can get it from google it & first result and then page 38)

so anybody know how to do it . any help is really appreciated

thanks
