HiIam trying to control the UART , PIO(led's and seven seg disp) ,etc through c-application programs in the nios IDE. I have included the "excalibur.h" include file which contains inf about memory map of the peripherals , default functions ,etc. Now when iam trying to send any character using the function "nr_uart_txchar(int c, np_uart *)" it's showing an error as "undefined reference to nr_uart_txchar()" .This is the problem even with other functions like: "nr_delay()", "nr_uart_rxchar()",etc. None of the default functions are getting executed. But iam able to use the data structures like np_pio_data,etc and iam also able to set the direction and also interrupt priorities,etc .The problem comes only with the functions. Can someone help me out of this problem??????
Your problem is that old Nios software does not work with the IDE. You have two choices:1. Migrate your software to the new interface - recommended 2. There is a legacy mode included which does things the same way as Nios 1, however the same way means no IDE This is all explaine in application note an350.pdf
