[coreboot] Coreboot and stand alone filo

[Masoud Fatollahy]

thanks again,

Now i have tested it with the new FILO together with coreboot and 
payloadlib, but get the same result. I can see that coreboot writing the 
table with the signature (LBIO) on  address: 0x00000500, but FILO can't find 
this signature when it search the address range.

what should i do? how can i debugg this? I print out the whole memory during 
the FILO search and can not see any LBIO signature.

regards,

/Masoud

thanks for the response,
 
I have downloaded the latest version of filo from Subversion with
$ svn co 
svn://coreboot.org/filo/trunk/filo
 
but this version requires the payloadlib of coreboot, it is what i don't 
want to use

Why?


, is there any other version which doesn't requir 
coreboot/payload/payloadlib?
 

Yes but you will have to fix it yourself, as I wrote in the other mail..

Hi, 
 
I am trying to make coreboot v4 works with a old version of filo(stand 
alone).
 
I build the coreboot and definde a paload which has been build with an old 
filo which is not using payloadlib of the coreboot. 
when filo try to read the linuxbios table , but it can not find the 
signaturr LBIO. and it hangs.
 
 Do i have to use filo and payloadlib of the coreboot, or is it a way to fix 
this problem. we don't want to have any depency between coreboot and filo.
 
thanks,

Hi Masoud,

The coreboot table parser in older FILOs does not support the "FORWARD" tag

http://tracker.coreboot.org/trac/coreboot/browser/trunk/payloads/libpayload/arch/i386/coreboot.c#L140 


I'd suggest that you use newer versions of FILO. However, implementing 
support for that tag in older versions should be rather straight forward, so 
you can give that a try, too..
