Problem with first run

This is a newbie question.

Installation and upload of the kernel and file system went smoothly on my 1s10 development board. Howerever first connection via terminal with the uClinux failed with the following message: Warning: unable to open an initial console although LED/7seg. counter did run. I will appreciate if anybody could help me. The configuration of my system and full listing of the terminal window are:

- Quartus 4.1 SP2

- Nios II

- ByteBlaster JTAG UART

- free RJ1 Ethernet socket

- no CompactFlash card on the socket

Listing:

[SOPC Builder]$ nios2-terminal

nios2-terminal: connected to hardware target using JTAG UART on cable

nios2-terminal: "ByteBlasterII [LPT1]", device 1, instance 0

nios2-terminal: Warning: The JTAG cable you are using is not supported for Nios

Sounds like its possibly a problem with the console device node.

In the filesystem project that you have, can you double check that there's a file called:

<project>/target/dev/@console,c,5,1

If the file doesn't exist, try creating a blank file with the name I just provided. Re-build, and re-upload your filesystm project as detailed in the Getting Started Guide.

I'm about to leave for the weekend but I'll be back on Monday morning if my advice above didn't work.

Thaks for your help.

This is weird but I didn't have /dev/ subdirectory under my filesystem project at all...

oh... hmm... if you build a new filesystem project, does it include the /dev directory? I believe you need to enable the "base" package when configuring the filesystem project through the "new project wizard".

Yes, but the weird thing is that I did it. Second attempt to build a new filesystem from the scratch was OK. Anyway thanks for your help again.

Looking at the kernel commandline, I noticed that you passed:

root=/dev/hda rw

/dev/hda represents the entire disk/drive. What you want is to specify a partition. In your case, that would be the first partition.

So your kernel command line should read:

root=/dev/hda1 rw

Give that a try... I think that should solve the problem.

the cf is formatted with ext2fs.hda1 has bootable primary partition,as the quick guide suggest.

we also have tryed with the correct device minor-major number(hda is 0301,as the file on /dev indicate)
no boot,the bios cannot found the device(unknown block(3,1) )
