Hello,
I'm using the uCLinux ported by Microtronix. I'm trying to use the web server but I can't see the initial page. I use the open core ethernet. I built the filesystem as described in the linux quick start guide. I can use ftp and telnet but when I type the IP in the web browser, I can't see the web page. Can someone help me? Thanks a lot, MarcoLink Copied

If you log in and run ps, does boa appear in the process list?

A silly question, but /home/httpd does have stuff, and you're either running boa as root or have the permissions set properly?

- under /home/httpd are the files index.html and ukit.jpg (Microtronix example)
- boa is started by rc script (see below). In difference to the example, I added the line /bin/ifconfig... # !/bin/sh# # system startup. # set up the hostname /bin/hostname Nios2 # expand and mount the ramdisk /bin/expand /ramfs.img /dev/ram0 /bin/mount -t ext2 /dev/ram0 /var -n /bin/expand /ramfs.img /dev/ram1 /bin/mount -t ext2 /dev/ram1 /tmp -n # mount proc file system /bin/mount -t proc proc /proc -n # mount sysfs /bin/mount -t sysfs sysfs /sys -n # manually assign ip address (uncomment and edit as appropriate)# note: first ifattach (no args) sets local loopback /bin/ifattach# /bin/ifattach --addr 10.1.1.99 --mask 255.255.255.0 --net 10.1.1.0 --gw 10.1.1.11 --if eth0 /bin/ifconfig eth0 192.168.1.239 netmask 255.255.255.0 # try and get ip address automatically...# /bin/mkdir /var/dhcpc# /bin/dhcpcd -NRY & # start up the internet superserver /bin/inetd & # start up the web server /bin/boa & # mount Linux server:# (uncomment and edit as appropriate)# /bin/mount -t nfs 192.168.1.30:/home /mnt/nfs -n -o nolock # mount master ide disk partition(s):# (uncomment and edit as appropriate)# /bin/mount /dev/hda1 /mnt/ide0 -n # that's it... success exit 0- Mark as New

In home/httpd there are only the files index.html and ukit.jpg
index.html is a html script. These files are working.- Mark as New

Ok, can you be more clear about how you don't see the web page? Do you get a 404 response? Does the query time out and you get nothing?

When I enter the IP in the web browser, the browser found the IP, but the site is not loaded.
I have logged the network traffic (with Ethereal). The traffic stopped after 5 packets. I can't attach the log-file today, because it's located on another PC.- Mark as New

What is the result if you try it manually, i.e. from some other (preferably unix) computer:
<div class='quotetop'>QUOTE </div> --- Quote Start --- telnet [ip of board] 80 GET / HTTP/1.1 Host: [ip of board][/b] --- Quote End --- (note that you have to hit enter twice after the Host: line. What do you get back, if anything? (note: you're using telnet to be an HTTP/1.1 client with the board as server; you can do this from the board itself if that's your only unix system available.)- Mark as New

I have captured the ethernet packets, as I called the website.
There are 2 HTTP Packets 1. packet GET /index.html HTTP/1.1 2. packet Continuation The second packet includes the last 77bytes of index.html. But where is the beginning data from index.html? Next, I tried to create a new smaller index.html. <html> <head><title>Test</title></head> <body bgcolor="white" text="black"> <td>Hello</td> </body> </html> J copied this new index.html into home/httpd Now I can see it in the web browser. As I now captured the traffic, I saw 2 packets again. 1. packet GET /index.html HTTP/1.1 2. packet HPPT/1.0 200 OK (text/html) This 2. packet includes the index.html. Whats wrong with the bigger index.html? Where is the first data? And what is the packet Continuation?- Mark as New

What direction were those packets in? If you could label every packet with its direction, that would be helpful.

So what do you get in response if you do:
<div class='quotetop'>QUOTE </div> --- Quote Start --- telnet 192.168.1.239 80 GET /index_old.html HTTP/1.1 Host: 192.168.1.239[/b] --- Quote End --- (note the extra blank line at the end.) What does the server send back to you?- Mark as New

telnet open 192.168.1.239 80 ? Then I have no response until the timeout is reached.- Mark as New

Can you use a unix box or telnet from cygwin under windows? I'm not familiar with the toy tools that come with windows, and I don't think that windows telnet is powerful enough to do this sort of debugging.

I have tested with telnet under linux. I created 2 testcases. Case 1 was a small website. In case 2, I added some characters to this website.

Ok, so we can see where it's failing, at least (at Boa's end, before it tries to do anything at all).
Man it would be nice to strace boa to see what it's up to. Failing that, can you cat the file on the filesystem? I mean, just make sure that any old process can read it successfully. Also, can you try creating an html file of roughly the same size as old_index.html just to try to eliminate size as an issue?- Mark as New

I made some tests with filetransfer over ftp yesterday.
I can transfer files with any filesize (small and large files) to the uCLinux board. but I couldn't download these files from uClinux board to the PC. I only could download files with size smaller than approximately 520bytes. That means files fitting in one ethernet packet. I think there is a problem with tx-buffering in the ethernet kernel driver. When I compile the kernel, I receive some warnings in open_eth.c.- Mark as New

Hello,
I solved my problem. I think the reason was the clock delay (phase) for the SDRAM. To solve the problem I changed the CPU clock in 2x Ozsillator clock (65.536MHz). The delay for the SDRAM clock is 170 degree. Now it runs on the Microtronix Cyclone 1C20 Developement board.- Subscribe to RSS Feed
