Hi all, I am using a DB64360 with a single 7455 processor and I am having a problem that is driving me nuts. I have a PCI card that contains a P2P bridge and an serial bus controller behind it. I am trying to use it under Linux and I can't seem to get the required resources. I have this card working under an ev64260 though. The serial bus controller requires 3 regions: BAR 0: 1 MB non-prefetchable BAR 2: 2 MB non-prefetchable BAR 4: 64 MB prefetchable.
I use u-boot as my bootloader (although Dink 32 gives me the same problems under Linux) because I am a bit more familiar with the code. I get error message when the kernel scans the bus saying: PCI: Cannot allocate resource region 1 of PCI bridge 2 PCI: Cannot allocate resource region 2 of PCI bridge 2 PCI: bridge 2 resource 2 moved to 9ff00000..9fffffff PCI: Cannot allocate resource region 0 of device 02:00.0 PCI: Cannot allocate resource region 2 of device 02:00.0 PCI: Cannot allocate resource region 4 of device 02:00.0 PCI: Failed to allocate resource 0(0-fffff) for 02:00.0 PCI: Failed to allocate resource 2(a0000000-9fffffff) for 02:00.0 PCI: Failed to allocate resource 4(a0000000-9fffffff) for 02:00.0 Any ideas why this may be? I am really at a loss and I was hoping for a bit of insight. I am attaching the complete log from u-boot to Linux including an lspci ouput at the end. As for hardware, I am using a DB64360 with 7455 at 931 Mhz. The Discovery II part is a rev A2. The kernel is 2.4.21-pre7 from the _devel tree, along with your most recent work from the _galileo tree. Everything else is working well but this card is giving me huge troubles. Any help would be greatly appreciated! Thank You Brian Waite ** Sent via the linuxppc-embedded mail list.
