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

It might be problem in mtd maps.
That's why, I would prefer using initramfs as a beginning.

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

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.
