porblems when generate the zImage

Altera_Forum · ‎06-10-2006

hello guys, i have encounted a problem and came for your kind help.

to generate the zImage file, i input the command 'make', then it has the following errors, what should i do? need to make some patches? i've patched the uClinux-dist.diff.gz provided.

[bigmagic@tu053020 uClinux-dist-test]$ make

make -C tools/ucfront

anybody met similar problem before? please give some advice on it, thank you very much!!

You need a full-featured timer in your sopc builder.

thank u very much hippo, i added a timer in the sopc builder and the problem is solved.

i compile the kernel under linux, but now that, it shows cannot find nios2-elf-gcc, i should install something else?

thank you again.

What is the message?

check if you have "cc" which is a symlink to "gcc" ?

cc -v

if not,

su -

cd /usr/bin

ln -s gcc cc

Check if you have nios2-linux-uclibc-gcc,

nios2-linux-uclibc-gcc -v

if not, setup the PATH.

hippo,thank you for you kindness, i will try it when i get back to the lab tomorrow.

another question, what's the size can a smallest uclinux be? is it able to be uploaded to a flash of only 2M BYTE?(with kernel and the file system)?

The smallest size of compressed kernel (with initramfs) is around 600KB.

It will grow if you enable more kernel config or more apps,data etc.

The compression rate is around 1:2 .

If you didn't use complex programs such as ssl/ssh , 2M should be enough.
