Understood, then I should better buy an Avila board.

Is there anything I should know before doing so, like board version, options or whatever ?

Thanks, Roman.

The qmgr option is already in the AVILA kernel config, I am not sure what you meant Sam ... Shall I use another version of the IAL ?

There is no IAL in freebsd. The qmgr support is there; see the ixpqmgr0 probe line above. This issue is likely that you need to tweak the npe topology in if_npe.c; UTSL. At some point the wired down assignments are to be replaced by hints. However once you get past that you still will hit the issue with the qmgr I spoke of originally--it does not support A* boards. I have no idea what will happen.

Well, at least I now have something that looks like a FreeBSD kernel starting to boot :-)

Thanks, Roman.

Thank you all for your answers,

It seems the explanation is just hereunder, I hope to find some time to give it a try today. I will also check the UARTS btw, it does have two ports indeed.

I do not know if A* boards are common, the one I have is quite old I think, so I guess no. I actually need to evaluate the performance of the IXP42* plateform. If I run in too much trouble with this old board I might well go for an avila. We (you) probably don't want to spend much time on this particular one.

I will get back to you asap with the results.

Thanks, Roman.

Hi,

First of all, congratulation for the work being done porting FreeBSD to the IXP425 !

I have an IXDP425 eval board rev A3 from Intel on which I tried the AVILA procedure as is, just in case, strictly following information from: http://people.freebsd.org/~sam/README-gateworks

My IAL replacement code does not support A3 revs. To fix that you need to add to the qmgr support as the A3 hardware does not have certain functionality the current code assumes.

I assumed A* boards would be rare; am I wrong?

Unfortunatly it will not "go", but just freeze: RedBoot> reset ...

Does anyone have experience with this board ? Does it have any chance to work w/ the AVILA kernel config, or is this one too specific ?

I am using FreeBSD 7.0-CURRENT #0: Thu Dec 14 16:10:30 UTC 2006

It should definitely get further than that but I wouldn't expect the npe support to work right. Try enabling bootverbose by patching the code (since we don't have proper bootstrap support yet to pass that in from redboot).
