buildroot to build toolchain on Linux

Sorry to jump in like this...

I managed to compile, build and run 2.6.11 acording to your procedure - I apreciate very much your effort and I'm hopping I speak for a lot o people watching this forum.

Of course, I did run into a few problems after booting:

First, my network interface (OpenCores EthMAC + TDK PHY) doesn't want to work. I get to see the link status (100FDX) when I connect the cable and configure the interface, but that's about all.

This, however, is going to require some more work on my part.

The reason I'm writting under this topic is that I get the following messages (boot time or dmesg) and don't know if it's going to affect the operation in a very bad way (or not).

(This should be the NO NETWOK kernel, in spite of the messages you see bellow !)

Why do not find the command : nios2-linux-uclibc-gcc? Thank you.

Hi hippo:

I successed setting net setting.

1) select Netsetting in menuconfig

2) select the fact mac/phy product of net device in menuconfig

The correct setting commadn is:

# ifconfig eth0 netaddr 192.168.0.85 netmask 255.255.255.0 up

Sorry, I am not good at network. Maybe someone better help out.

First, check if you have your net device in kernel menuconfig.

Next, check the boot up message if the net device init.

Hi hippo:

I am testing boa and DHCP now.

Frist I must config the ethernet setting. I use the ifconfig command as follow:

ifconfig eth0 inet addr:192.168.0.85 Mask:255.255.255.0 up

but I find the command not setting my dvb success.

I use ping command use loopback address(127.0.0.1),it's OK.

I think the problem maybe I use wrong config method.

I want to use ifconfig -h command to look for help,but no any information display.

Can you help me? Thank you.

Hi Alex,

Great!

How about user's apps, such as BOA, dhcpd ..etc ?

HI HIPPO:

I make successed,and run in my dvb.

Thank you.

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 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.
