The boot loader we used was openbios, which was already installed in the flash. We ported a part of ppcboot to linux kernel to complete the pci configuration. Now pci is running well on our Walnut. What we did was: add the function "void pci_init(void)" in in ppcboot directory into "void __init pcibios_init(void)" in Some minor changes were needed such as functions/macros renaming. The conclusion is that ppcboot configures pci well. Above is one of solutions. Swapping openbios with ppcboot will be good. Downloading and running ppcboot, then downloading linux by ppcboot seems well. hideo "dony.he@huawei.com" wrote: > Now I have the same problem as you meet before. > Have you find a good solutions? > Thank you very mcuh. > > machael > > > > > Hi, > > > > I am trying to install Intel eepro100 onto WalnutPPC405GP. > > Basic PCI settings seem good but no frame is transmitted. > > The environment is WalnutPPC305GP with HardHatLinux 2.4.2 from > > MonraVista. > > > > I can read or write eepro configuration registers and other control > > registers via PCI memory space. > > But Bus Master operations do not seem functional.
