内核中
System Type->Freescale MXC Implementations下的PCI Express选项
PCI Express support
[ ] PCI Express EP mode in the IMX6 RC/EP interconnection system
[ ] PCI Express RC mode in the IMX6 RC/EP interconnection system
在内核中通过补丁pcie_cap_patch.patch 向kernel中添加TW6865相关的驱动和配置；并在内核的选项选上tw68系列的encoder的编码器
<*> Multimedia support --->
Video capture adapters --->
Encoders, decoders, sensors and other helper chips --->
<*> pcie TW68 video encoder
内核启动log如下所示：
PCIE: imx_pcie_pltfm_probe start link up.
link up failed, DB_R0:0x004a4a02, DB_R1:0x08000000!
IMX PCIe port: link down with power supply 1!
应该怎样解决？ |
