Altera_Forum · ‎02-13-2006

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!

Altera_Forum · ‎02-13-2006

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.

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

Altera_Forum · ‎02-15-2006

You should do the "touch" command after "./build" finished.

What can I do? Thank you!

Altera_Forum · ‎02-17-2006

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.

Altera_Forum · ‎02-17-2006

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

Altera_Forum · ‎02-17-2006

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.

Altera_Forum · ‎02-17-2006

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.

Altera_Forum · ‎02-17-2006

HI HIPPO:

I make successed,and run in my dvb.

Thank you.

Altera_Forum · ‎02-17-2006

Hi Alex,

Great!

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

Altera_Forum · ‎02-20-2006

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.

Altera_Forum · ‎02-20-2006

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.

Altera_Forum · ‎02-20-2006

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 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.

Altera_Forum · ‎02-21-2006

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.

Altera_Forum · ‎02-21-2006

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.

Hi hippo,

Thanks for the prompt answer.

You see, my network driver is not really ready, yet. So, for my tests I configured the kernel without network support (NO NET).

For the network part I was, mostly, concerned with why I still see some netwiork messages. The network is not a major concern of mine, just yet.

Now, I know the goal here is to be able to use initramfs and, because of that, the cfi & mtd-related messages are what i'm concerned about.

"

.....

failed to ioremap

.....

mtd: partition "romfs" is out of reach -- disabled

....

"

Where do these come from and what (if anything) should I do about them ?

(of course, I could read the sources and figure out for myself, but the time I have is very, very limitted)

Also, I am going to need access to the flash in the very near future, so I'd like to be able to mount readonly a flash partition, if at all possible. That's why I did not totaly removed the MTD and CFI options.

What would be the minmal options to be able to access the AMD flash on the eval board and nothing else ?

Thanks again,

Daniel
