/bin/init hangs

Altera_Forum · ‎05-03-2006

hi all,

I am trying to boot uclinux on 2s60 board. where my kernel is hanging

moment it calls /bin/init. I have build uclinux with changed memory layout

where base addresses and irq number differs then default memory layout .sof and .ptf files

given by microtronix. Also I have remover support for compact flash in my case.

I can boot uclinux build from microtronix .sof and .ptf file on the board with similarly

generated file system. I tried "root=/dev/mtdblock0 ro" as well as nfs boot with root=/dev/nfs ro,

and seems fine (nfs boot init gives error with init: execv failed, but get login and prompt ok) .

But when I give my memory layout sof and ptf file the compilation is successful but kernel

get hangs when he calls /bin/init.

Any one has any idea why it is happing so???

Do I need to build new busybox ???

Is it not possible to boot uclinux with custom memory layout on Altera boards ??

Do I need to change my quartus-II 4.2 and nios-II 1.1 versions ???

Any suggestion where I am going wrong ???

If any one need I can post my sof, ptf and nios2_system.h files.

thanks in advance

Ankur

try the buildroot guide and work on a Linux box, it is easier to use and customize.

What dose it mean ? Could you post your *.ptf here?

If kernel starts up and gives log messages, It seems your hardware(sof) is OK, so maybe there are mistakes in kernel config and rootfs.

It might be problem in mtd maps.

That's why, I would prefer using initramfs as a beginning.

You can't success on nios2 uClinux without Linux knowhow.

I realy feel it is totally wrong to develope Linux/uClinux on Windows.

What is the last message of init?

check etc/inittab in your rootfs.

or you can used the sample inittab attached build0411.zip of buildroot guide.

hi hippo, lefred and all,

I saw lefred linux boot dump which is different than mine. In my case

I get these prints...

VFS: Mounted root (nfs filesystem)

Freeing unused kernel memory: 64k freed (0xxxxxx - 0xxxxxx)#

I am able to get prompt "#" and it gets hang, i.e. Counter on seven segment

display get stop and led glow freezes.

But before going into some more discussion first let us try buildroot !!!

thanks

Altera_Forum · ‎05-04-2006

Some suggestions:

1. Sometimes the kernel can't necessarily detect what the filesystem type is on flash so you might add rootfstype=jffs2 or whatever filesystem type you are using to the kernel commandline.

2. You may not have compiled in the block driver for flash so you need to have at the very least the CONFIG_MTD_BLOCK=y in your .config file.

3. The kernel also needs to have the filesystem type used compiled into it.

hi hippo and all,

I am facing some issues while running ./build script for buildroot.

looks like nios2-linux-uclinux-gcc is missing in my case.

I can't make out where I went wrong, could you please just have look

over the error print and kindly help me out of this problem.

Is there any thing else I need to download for running buildroot ???

I have downloaded all the packages (snapshots) from my windows m/c as I am not familier with wget [my sys wget is not able to resolve web addr !!!].... etc.

thanks

which linux distro do you use?

check your buildroot/build_nios2/staging_dir/bin,

are there the cross gcc?

I would suggest you put the buildroot dir in your home dir as user. ie ~/buildroot .

please try, rm -rf ~/buildroot/toolchain_build_nios2

and make again.

hi hippo and all,

I am using redhat - 9 on my host system for develop.

Cross gcc is not there in buildroot/build_nios2/staging_dir/bin....

Now I have shifted buidroot dir in my home dir but still its failing with same error...

I read that redhat-9 "make" has some problem ... do I need to update my host system linux-ver to some Fedora version.

Do I need to build cross-uclibc-gcc by my self or buildroot will do it for me ????

thanks

Ankur

The "make" of redhat is too old.

You should use Fedora Core 5.

The buildroot will build the cross gcc.

I have prepared the binary buildroot tools, you can try it without building buildroot.

hi hippo and all,

I tried your binaries and it worked http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

What I actually did is ... on my redhat-9 system I untared your pre compiled gcc and stuff, then through your already build file system's help I build my kernel and it worked perfectly fine.

I can now see file system in ram file system boot. But still facing some issues with nfs root ....

It doesn't look like any problem with buildroot or file system ....

I am getting following error while booting same kernel with nfs boot support enable

mm/vmscan.c 736 Kernel BUG!

mm/vmscan.c 738 Kernel BUG!

.

What I found is I have enabled bit swaping feature in my nios processor in fpga configuration. Next I will try disabling it and will update result on forum.

Thanks for all your help

Ankur
