buildroot to build toolchain on Linux

Hi Alex,

Great!

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

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.

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 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

hi hippo:

I make boa ,dhcp, netsnmp ,but failed.

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

Your PATH may not have the cross gcc.

check step4 in post#1.

try "nios2-linux-uclibc-gcc -v"

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 !)

I make the http and boa in uclinux-dist-test and successed.

Then I copy boa.config to /rootfs/etc/config/ after I reworked the original boa.config. I make dir /rootfs/home/httpd and I put my index.html in the dir.

copy boa and http exec file to /rootfs/bin.

make kernel again for intramfs.

I download the vmlinux to cyclone1c20 dvb,and it init ok.

I can visit index.html in dvb when I use http as webserver.

But when I use boa as webserver, the uclinux will restart when I viset it use

IE.

HI dumdan,

You are very close to sucess.

1. start with minimal kernel config, (copy kernel2.config to .config).

2. check if you have network support and your opencore emac / tdk phy in kernel menuconfig, better compile-in kernel, instead of modules.

ie, minimal config + network + emac + phy

3. cfi, mtd,ramdisk,and kernel command line are not required in kernel config, because we use initramfs.

4. boot uclinux, and check if the eth0 init sucessfully.

Hi Alex,

1. Are you running linux-2.6.15.4? Please try linux-2.6.x first.

2. Is the httpd, which sucessed, from busybox?

3. should boa.conf and mime.types be placed in rootfs/etc ?

4. try check some debug messages from boa.

..I am really not good at network, sorry.
