Still not having success with SM P4DPE

[Atherton, Stephen]

Ron and James, thanks for clueing me in on the fallback image stuff.  I'm
still not quite doing something right though, it seems.

My config files are below.  I based these on the samples in
mainboard/supermicro/p4dpe.  The fallback image is 81k and contains the
etherboot payload...this doesn't seem right to me but I don't know what else
to do.  If I don't specify the etherboot payload, it tries to use vmlinux
which is much, much bigger.

So I run the config script on both files, then go to the fallback/ and
primary/ directories and run make, and I get a primary romimage of 458752
bytes and a fallback image of 81920 bytes.  That doesn't seem right.  What
am I doing wrong?  Oh and though I was doubtful, I did do a "cat
primary/romimage fallback/romimage > finalimage" and burned the final image.

Also, from the looks of the makeprocess my two image files are basically the
same binary stuff but one has a lot of null padding.  They both contain the
eepro100 elf image and linuxbios.rom...

Anyone see what is wrong with this picture?

Greetings,

It looks like the fallback image is being built wrong.

This can be hacked together manually. linuxbios.strip should be the actual
LinuxBIOS code. The objective is to assemble a 64K (exactly) block
containing:

1. etherboot
2. null padding (can be generated with dd if=/dev/zero)
3. linuxbios.strip.

I just use calctool to figure out how much padding to use and
cat eepro100.elf pad linuxbios.strip >fallback.bin

the 64K fallback.bin can then be appended to the primary image to get the
full rom image.

That's a little ugly, but it should get the job done.

Just as a final verification, in linuxbios.map, ZKERNEL_START for the
fallback image should be 0xffff0000. That is whjere it will look for the
fallback etherboot. Also, it will ljmp to ZKERNEL_START-8 to transfer
control to the primary image. I'm slowly trying to disentangle that on the
boards I have. Unfortunatly, I don't have a P4DPE.

G'day,
sjames

[ron minnich]

to simplify this I'm going to just show you my files, which work. I just 
built a linuxbios yesterday that worked fine on the P4DPE-G2.

my romimage sizes for this are 64K and (512k-64k)

Note that fallback size is 40K which with the 24k etherbooth gives you 
64k.

I think your normal file has a typo on the rom image size.
