I have a Nios II system that is running Linux 3.10.31 and I would like to update my system configuration so that the kernel debug messages during bootup that are sent to stdout are routed to a standard UART instead of the Altera JTAG UART.
From my understanding, what I need to change is the following:
- Add a UART component to my Qsys system and connect to the Nios II processor.
- In my kernel configuration (menuconfig), I need to disable the Altera JTAG UART serial and turn on the enable the standard UART (8250/16550 compatible) serial port.
- In my console boot parameters, I need to change the console output from ttyJ0 to ttyS0
If all is good, I should be able to use minicom to access the ttyS0 port to see the debug output.
Does that sound right or am I missing anything?
Any feedback would be appreciated. I look forward to your response.
