我在iMX6 SabreSDB单板上,通过PCIe接口连接了TW6865视频采集卡(支持4路视频,4路音频),
编译kernel时,选项加了:
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
编译出kernel后,可是NFS启动加载新编译出的kernel,lspci命令显示找不到设备
root@freescale ~$ lspci
lspci: /sys/bus/pci/devices: No such file or directory
并且在kernel启动过程打印的信息中也没有关于PCI的信息,求助!!!
