Serial Console

I have been trying to get a RS232 console to work for a couple of days now. The kernel I have works great, but I can only use USB-Blaster as terminal. I though it would be as simple as enabling the "Support for console on Nios UART" in the Device Driver -> Character Dev -> Serial Drivers. When I select this, the kernel will build properly, but neither the USB-Blaster or the RS232 dumb terminal worked. Any help would be appreciated. 

 

Thanks,

Hi, 

 

u have to do another configuration : in your file system, edit /etc/inittab and : 

 

--> comment line begining by ttyJ0 

--> uncomment line begining by ttyS0 

 

your file should look like the following : 

 

# inittab for uClinux# Format:# ttyline:termcap-entry:getty-command ttyS0:vt100:/bin/agetty 115200 ttyS0# ttyS1:vt100:/bin/agetty 115200 ttyS1# ttyJ0:vt100:/bin/agetty 115200 ttyJ0

Thanks! Only one problem... I don&#39;t have "inittab" anywhere on the file system. Could this be why I can&#39;t inlcude "init" in my file system? How can I get the builder to make one or where can I get a template? 

 

Thanks,

Relax. 

Life is easier on Linux. 

Throw the Microtronix&#39;s uClinux guide away. 

Take some time browing the nios wiki for uClinux. 

And try out the pre-build image.
