buildroot to build toolchain on Linux

Thank you very much! I get the toolchain ,then kernel!

But how do upload the kernel file to flash ?

Who can teach me ?

Who can write a doc ?

Thank you !

Sorry ,my english so poor!

You should find them on the nios2 doc and the forum.

You should download to ram first, and after you have a lot of tests, then download to flash.

check,

Sorry, I can not help you. I don't use CFI flash.

hi hippo:

I have a question aboot follow reference:

*************************************************************************

NOTE : the inittab was missing when patching the uClinuc-dist-test, add it with

CODEtouch ~/uClinux-dist-test/vendors/Altera/nios2nommu/inittab

*************************************************************************

I have already download uClinux-dist-20051110.But I didn't find the uClinux-dist-test. Where is the uClinux-dist-test I can download?

Thanks

hi hippo:

I uesed exec ./build commaand,but i got a erro.

The erro informathion follow:

What can I do? Thank you!

Attached is the zip containing the kernel's usr/initramfs_list. You should have the similar file AFTER the kernel build. If you can't boot kernel, attach the zip containing your file in the post.

You should check the .config of your kernel. Compare it with the file kernel.config in build.zip, the only diff should be atlera jtag console. It must have correct initramfs setup.

Hi Alex,

I think you are using the latest buildroot/uClibc which have problems.

Please use the new build0207 script attached in post#1, remove line 1-34, which prepares source for kernel/uClinux-dist. Remove old ~/buildroot, and run ./build0207

hi hippo:

I remove old buildroot ,rootfs, linux-2.6.x, linux-2.6.15.4 frisst.Then rebuilded the toolschian follow your new update with ./build0207.

But I still failed .I think the failed reason is ccache.samba.org web site

I got follow informathion:

I will search other web to obtain the ccache-2.4.tar.gz, then download it in ~/download dir.If you know other web site what have the file ,pelease tell me.

2) I make process, I got other information about watchdog.

patch file drivers/char/watchdogs/Makefile

Hunk# 1 Failed at 39

1 out of 1 hunk Failed -saving rejects to file drivers/char/watchdogs/Makefile.rej

Hi Alex,

1. the ccache is not required, you can disable it.

cd ~/buildroot

make menuconfig

Toolchain Options--> [ ] Enable ccache support?

make

2. Ignore the watchdog patch fail of the new kernel. You can update the watchdog Makefile later.

HI HIPPO:

I make successed,and run in my dvb.

Thank you.
