[hawkboard] OE Kernel Not Booting

[Christophe Aeschlimann <c.aeschlimann@acn-group.ch>]

Hi,

We are at least three hawkboard owners that have the same issue.

Building org.openembedded.dev HEAD with

MACHINE= "hawkboard"
DISTRO = "angstrom-2008.1"

produces a Kernel Image that cannot be booted on our hawkboards.

The behaviour is the following with the following kernel bootargs :

console=ttyS2,115200n8 root=/dev/nfs 
nfsroot=172.16.147.10:/srv/nfs/hawkboard ip=172.16.100.100 
eth=0a:c1:a8:12:fa:c0

And it hangs there forever...

If I add earlyprintk to the bootargs :

console=ttyS2,115200n8 root=/dev/nfs 
nfsroot=172.16.147.10:/srv/nfs/hawkboard ip=172.16.100.100 
eth=0a:c1:a8:12:fa:c0 earlyprintk=serial,ttyS2,115200n8

then I get the following :

And it hangs there forever.

Could someone who has an hawkboard working with OE please detail his 
configuration ? (u-boot, kernel config)

If you have any idea of things I might try to get it working is also 
welcome. Like how to start debugging that ?

Best regards,
