Hi all,
I am trying to bring up a small WinCE based terminal with LinuxBios instead. I'm using the eaglelion/5bcm as a starting point. With this the system comes up, starts etherboot, etherboot loads my Linux kernel (up to text "....done") and then nothing more happens.
Some things confuses me:
.... Devices initialized Copying IRQ routing tables to 0xf0000...done. Verifing copy of IRQ routing tables at 0xf0000...failed Wrote linuxbios table at: 00000000 - 0000017c checksum 2df2 ....
I read in the archives that this failure could be solved be undefining CONFIG_COMPRESS. But it did'nt help. Any other hint to solve it?
When etherboot starts:
..... Etherboot 5.4.2 (GPL) http://etherboot.org Drivers: RTL8139 Images: ELF Protocols: DHCP TFTP Relocating _text from: [000100e0,000219a0) to [03aee740,03b00000) Boot from (N)etwork or (Q)uit?
Probing pci nic... [rtl8139] - ioaddr 0X1000, irq 0, addr 00:30:AA:00:25:1B 100Mbps full-duplex Searching for server (DHCP)..... Me: 192.168.1.5, DHCP: 192.168.1.2, TFTP: 192.168.1.2, Gateway 192.168.1.2 Loading 192.168.1.2:i586Linux ..(ELF).. ....done
Is "irq 0" correct at this point of time?
Does LinuxBIOS needs any preparations/patches on the Linux kernel to boot and run it? I tried with enabled framebuffer console (and activated screen in the Geode) and with console on serial port. Both without success (also I tried 2.4 and 2.6 kernels).
Thanks for any help in advance.

But it still hangs after downloading the Linux kernel :-(

Have you enabled serial console in your kernel config? and did you specify it on the kernel command line? (ie. console=ttyS0,115200n8)

Yes, attached. But I'm not sure if this is the right place to patch. Maybe there is a better place to enable this feature?

Yes I did. Its not my first embedded target that I bring up (but my first with LinuxBios). So that was the first I care for. The UART address seems ok, so I think Linux can find and use this device.

what version kernel?
enable early printk and boot with earlyprintk=ttyS0,115200,keep
and see what you get (copy to me)

I tried with 2.4.28 and 2.6.16.

It seems only true for 2.6 kernels, isn't it? I did not find any menu entry in 2.4.28 for this, right?

Sorry that's all. No more output after the word "done".
I also attach the kernel configuration file.
Maybe etherboot does a bad thing? I built this payload not by my own, I downloaded it from their website (as an "ELF (LinuxBIOS) ROM Image (.elf)"). I didn't touch any of the customising configurations.

All right, I tried now:

The behavior is a _little_ bit different.
<many dots snipped> ....done Unknown firmware type: LinuxBIOS Firmware type: PCBIOS
But nothing else. What does it mean?
BTW: mkelf-linux is from the mknbi-packet that I'm using for other etherboot targets.

Does anybody know who outputs this string? Is it etherboot or the Linux kernel? I cannot find these strings in the sources, neither in the kernel nor etherboot sources.
Juergen
for 2.4 you want eric biederman's early printk patch, and I have it *somewhere*, but can't find it.
