[syslinux] lpxelinux.0 - 6.02 - failed to load ldlinux.c32

[Petry Roman, SHS-S IT-TS]

Hello, after spending some time searching the mailing list and chatting via irc with some nice people i have to come to the list to ask for help.

First thanks again to some IRC guys: genec for taking some time and to Ady2..

 

First some background. I need to boot a 250mb initrd to some(later all)  of our thinclients , at the moment i´m using tftp but as we all know performance is bad.

 

I have 3 different hardware systems.

Model 1: msi itx board with realtek card with serial port

Model 2: shuttle barebone with intel atom and realtek card, just usb ports

Model 3: shuttle barebone with intel atom and jmicron card, just usb ports

 

I tried pxelinux 6.01 and also 6.02. No luck on Model 2 and 3. Model 1 is booting with 6.02 and 6.01 via lpxelinux.0 without a problem.

I used the stock binarys from the tar.bz , no make was issued.

 

I use this dhcpd.conf entry

host tc10143 {

        hardware ethernet 80:ee:73:5d:43:1c;

        fixed-address 172.31.126.125;

        option host-name "tc10143";

        filename "/thinclients51dev2/lpxelinux.0";

}

nothing more.

 

The client sends dhcp requests, get the options back and starts downloading the lpxelinux.0 via tftp. If the download is completed, it requests ldlinux.c32. it ack´s  the options tsize and bsize.. and that´s it.

Nothing more happens. I connected the client to a hub and did a wireshark trace with my laptop to be sure what happens. So i think the client just don´t start the second tftp get request for the ldlinux.c32 file.

After some time i get an : ldlinux.c32 failed to load.

Logfile from tftp server:

Oct 23 17:19:14 lin dhcpd: DHCPREQUEST for 172.31.126.125 (172.31.4.25) from 80:ee:73:5d:43:1c via 172.31.126.240

Oct 23 17:19:14 lin dhcpd: DHCPACK on 172.31.126.125 to 80:ee:73:5d:43:1c via 172.31.126.240

Oct 23 15:19:14 lin in.tftpd[21957]: RRQ from 172.31.126.125 filename /thinclients51dev2/lpxelinux.0

Oct 23 15:19:15 lin in.tftpd[21958]: RRQ from 172.31.126.125 filename /thinclients51dev2/ldlinux.c32

If someone want´s the wireshark capture i can upload it..

 

As i don´t have a serial console on Model2 and 3, is there a way to try to debug those things. Perhaps a way to display some UNDI Flags to the screen or some more Debug Infos also tot he screen ? Would a usb2Serial Converter help as a debug port?

Any hints are welcome .

Bye

and thanks
