using fprintf with stdout parameter in NIOS2

Hello.

If I want to write alternative output string to JTAG_UART and NIOS_UART can I use the function fprintf using the distenation as the first parameter?

Is it possible to chose the stdout during run or it must be define fix, and if I can what should be the parameter to place in for JTAG_UART & NIOS_UART?

Thanks

    Hi,

    Greetings and welcome to Intel's forum.


    Yes, you are able to write alternate output string to JTAG_UART and NIOS_UART.

    Here is an example writing to uart1 for your reference: https://www.intel.com/content/www/us/en/docs/programmable/683525/17-0/introduction.html (Section 7.7.2. General Access to Character Mode Devices)

    Unfortunately, you are unable to choose the stdout during run time so you will have to set it first.


    Hope this clarifies your doubts.


    Thank you.
