I am working on designing a custom PCIexpress card.

I am trying to write a kernel module that will DMA my custom card.

Right now when i plug the card into linux no valid PCI device shows up (meaning I probably have a error on my end, i know) however, If I halt the system at startup in the bootloader (uboot) I am able to directly access the card as I know in uboot the physical memory address that is mapped to my device.

Is there a way I can access the card in a simliar fashion in linux?

Thanks, Stephanie

Basic diagnostic information about PCI cards can be gleaned with lspci -vvv.

nothing shows up when i do lspci ... I think what confuses me the most is that I can talk to it in Uboot but not in linux... – Without me Its just Aweso Sep 1 '10 at 19:51
