hi,
i found a problem using a pci sound card in the DHT-WALNUT.
It has been correctly recognized by the kernel, the DMA feature (ppc405-dma) is setted, but the card is not working.
somebody says it is a bug, somebody says ppcboot solves the problem inizializing the pci in the correct way. I don't know, i'm using the uboot v1.1.4 and it is not working
also have a look to this

<> header type = 0x00
<> BIST = 0x00
<> base address 0 = 0x00000000
<> base address 1 = 0x80000008
could you help me to understand how to plug a soundcard ?
:)
best regards
