uClinux boot up

I have created uClinux filesystem using the distribution downloaded from this forum. When I power up the nios2 board, the uClinux can't boot up untill I open nios2-terminal. What is the reason?

Hi Writer,

Please check page 11 of the "Reference Guide.pdf", it says:

If the JTAG UART is chosen as the console, in order for the kernel to proceed normally, the nios2-terminal utility must be started, either through command line or Eclipse. This is because the JTAG UART FIFO will soon become full if no application reads data out of the JTAG on the other side, and printk (hence the kernel) will get stuck. Fortunately, just starting the nios2-terminal will bring an already stuck kernel back to normal. If starting nios2-terminal is not wanted, please disable JTAG UART console in the Linux kernel configuration.[/b]
