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.
