Dear all. I have a board that consisted of mpc7410+gt64260+pci_device, and I have already success to read/write the pci_device. After init the pci_device, I command to the pci_device that read data from main memory(sdram), but, the pci_device does not operate and return only fail...
I think that this is the DMA Problem... so I want to know that how to set the register of gt64260 to do DMA operation. I already set PCI SCS[0] Size Reg, PCI SCS[0] Base Addr Remap Reg, and PCI Base Address Enable Reg. what I omitted? or ... please help me... Thanks everybody. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
