22 years agouClinux 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?

16 years agoI am having this same problem where I cannot boot Linux (w/MMU) from flash until I connect the USB Blaster and run nios2-terminal. Once I do that, the code runs perfectly from and the messaging comes up on the JTAG console.
I have removed JTAG console support from my image which is what I thought was the problem. Here is snippet from my kernel .config: CONFIG_SERIAL_CORE=y# CONFIG_SERIAL_ALTERA_JTAGUART is not set CONFIG_SERIAL_ALTERA_UART=y CONFIG_SERIAL_ALTERA_UART_MAXPORTS=4 CONFIG_SERIAL_ALTERA_UART_BAUDRATE=115200# CONFIG_SERIAL_ALTERA_UART_CONSOLE is not set Yet, I still see the messages when I connect. Nothing happens in the hardware until I connect the USB Blaster. If I don't have a console, is that the problem? I would really appreciate help as this is urgent (and yes, it's Friday night.)
