buildroot to build toolchain on Linux

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

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 hippo:

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

The erro informathion follow:

What can I do? Thank you!

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

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,

http://www.altera.com/literature/ug/ug_nio..._programmer.pdf (http://www.altera.com/literature/ug/ug_nios2_flash_programmer.pdf)

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

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!

Hi nvs,

The .config is not related to ptf. The ptf is used to create a header file for hardware address.

When you run,

make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- hwselect SYSPTF=your_system.ptf

it will ask you some questions, like these. And you should make selections.

--- Quote End ---

You will always need a cfi memory for the hwselect perl script, even when you use EPCS. Just add a dummy cfi flash to a copy of your real ptf and make the hwselect happy. It is for hwselect only. You dont need it for hardware.

That&#39;s what required for hwselect,

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

You should start with a mininal system with only nios2 cpu core,dram,timer,jtag/serial console and a cfi flash, (which can be dummy and removed later). Note, the interrupt vector (ie, execption vector) should be in uClinux program memory.[/b]

You need a full featured timer.

Hi Sam,

Your Linux env may be too old. Please try install a fedora core 4.

Please select "development" pakages when you install the Linux.

And include compat gcc.

Hippo

Hi hippo,

My environment is gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-53). I try your new build shell script but still encounter the same problem which don&#39;t include bin folder in ~/buildroot/build_nios2/staging_dir. Do i need to change my environment or need to modify something?

Thanks a lot.
