MARVELL BOARD: RD-88F6281A -CURRENT

[Andreas Tobler]

Hi all,

I'm very new to arm hardware, but not to FreeBSD.
I got my hands on a broken (software like) ix2-200 Iomega StorCenter. A
few wires and a screen session allowed me to dive into it and I tried to
boot -CURRENT on it. Below where I end.

The config I used is the DB-88F6XXX with enabling the INVARIANTS etc.
The board itself identifies as the subject says. It has this:
Soc: 88F6281 A0CPU running @ 1000Mhz L2 running @ 333Mhz
SysClock = 333Mhz , TClock = 200Mhz
DRAM (DDR2) CAS Latency = 5 tRP = 5 tRAS = 18 tRCD=6
DRAM CS[0] base 0x00000000   size 256

Has anyone a hint or an idea where to start debugging this?

TIA,
Andreas
