Hello,
Working on a new CK804 board
Which board did you base it on? What are the differences?
I based it on the Asus A8N-E. The only differences are:
1. A8N-E supports 1 Athlon64 dualcore CPU, My board (Asus K8N-DRE)
supports
2 Opteron dualcore CPU's
2. SuperIO's are different.
I would think that there is a board that's more similar, then, but I'm
not
sure.
But besides that, all the rest of the hardware is the same as far as I
can
tell.
and I have it almost booting but it seems the
resource allocator does not like / or want to enumerate the CK804.
It fails before resource allocation, at device enumeration. It's hard
to tell from the log why it went south, but are you sure that the
Southbridge is on HT link 1?
I have no idea how can I tell?
Is there a way to tell what HT link it is on with the factory bios?
There are a couple of ways. lspci from the factory BIOS is probably
the easiest. There are a couple of registers that would tell you.
Try:
sudo lspci -xxx -s 18.0
Then look at the line that starts with e0:
mine is:
e0: 03 00 00 03 03 01 40 40 ...
From the BKDG:
Configuration Base and Limit 0–3 Registers Function 1: Offset E0h, E4h,
E8h, ECh
Remember that the byte order is little endian, and my registers are:
e0 03000003 - bus 0-3 on node 0 link 0 rw enabled
e4 40400103 - bus 40-40 on node 0 link 1 rw enabled
It is acually device 18.1.
Factory bios 0xe0=0x5000103, 0xe4=0,0xe8=0,0xec=0.
So that means I have - bus 0-5 on node 0 link 1 rw enabled
And that is it. So now do we tell coreboot about it?
maybe a custom resourcemap.c???
