hi, Herrenschmidt Thanks for replying to this topic! > That looks more like a HW error to me unless you are hitting completely > the wrong system addresses. The HW is OK. If I plug this card into another ppc board: mpc86641-hpcn, it works fine.

Would you mind telling me at what position should I add the printk? I can only print pci_iomap's return address which is mentioned in the previous mail, it is 0xfc7fc000. The following is part of the linux boot message: PCI host bridge /pcie@e000a000 ranges: MEM 0x00000000a0000000..0x00000000afffffff -> 0x00000000a0000000 IO 0x00000000e2800000..0x00000000ea7fffff -> 0x0000000000000000 /pcie@e000a000: PCICSRBAR @ 0xfff00000 Is 0xe2800000 the iobase_phys of the PCI bridge? So any suggestion is appreciated! regards, wolfking. -- View this message in context: http://linuxppc.10917.n7.nabble.com/can-t-access-PCIe-card-under-sbc8548-tp71775p71874.html Sent from the linuxppc-dev mailing list archive at Nabble.com. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
