About the nios-elf-gcc problem

Question

I install the tools CDK4NIOS and use nios-elf-gcc to compile the U-Boot-1.1.4.For the test,I input:

make DK1C20_config

make

......

The follow message is like this

make[1]: Entering directory `/root/u-boot-1.1.4/common'

I don't know what's wrong.Beacause I don't modify any file except set the gcc PATH.

I'll be very happy if anyone can reply.

Really, you should not user Nios, unless you are maintaining an old product.

You should move to Nios II. You can find evaluation software from Altera's site.

And there are binary toolchain, which you can download from Nios wiki.

It seems OK.

You may also try out the latest u-boot release 1.1.5 .

Next you will need to download to sdram, and try out.

Then you need to learn to program u-boot to flash.

You may search the forum and find a lot of helpful posts from Scott.

During your learning, it would be great if you can take down your experience on the wiki.

Finally, welcome to the wonderful world of Nios II.
