Greetings,
I'm a new Nios (I) user. I'm working in my final project about video coding within a FPGA and I've had problems with the communication between the pc and the Nios board. Until now, the idea is that I could send many bytes to Nios uart, corresponding to pixels from an image, and I could see them with a "printf". However, when I run my Nios sw code (in C), it waits and waits for receiving data and it blocks the serial port; so, my another program (which sends pixels from a file) in Java says "Port is busy". Besides, if I run first the program in Java, bytes are sent but the program in C doesn't work, it finishes inmediately.
Any help?? :roll:
Is it neccesary using interrupts?
Thanks in advance.
