Hi: thanks a lot for your advice. I have printed the value of PCI_RST(GPIO[13]) before switching from NAND to PCI, the value is 1. Itmeans PCI_RST has been driven high.
but the board still resets while the kernel calls "davinci_cfg_reg(DM646X_PCIEN)" in the file of board-dm646x-evm.c I just select the PCI bus support in the configuration of kernel,and I do not select the support of mtd and ata in kernel. shoud I do some configuration about the Davincihd1080p evm while it acts as a PCI host? best wishes! _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
