openwrt x86-64 编译问题

[debiansid]

自己编译的固件无法认出 rootfs ，官方的就可以。
rootfs 在 cf 卡上，请教下 ata_piix 如何编译进内核？

[coffeecat]

如果有挂载其他硬盘，改编译选项 /dev/sda 为 /dev/sdb 看看，或者单独挂载 cf 卡

另外查查 ata_piix 的 dependent ，全部编译进去就行

@coffeecat ata_piix 选项在 kernel_menuconfig 里面选？

@coffeecat 还是一样问题， 无法认出 root device

[debiansid]

root@openwrt-x86:/# df -h
Filesystem Size Used Available Use% Mounted on
rootfs 46.5M 32.4M 13.1M 71% /
/dev/root 46.5M 32.4M 13.1M 71% /
tmpfs 998.7M 2.3M 996.4M 0% /tmp
tmpfs 512.0K 0 512.0K 0% /dev

先用 trunk 先顶住，看看怎么解决这个问题吧

[debiansid]

问题应该是自己编译的内核没有 sata 驱动，且不能作为模块编译，今天再试试

[debiansid]

@coffeecat 官方的完全没问题

[lisaac]

@debiansid 查查看是否是引导问题，具体情况看你目录结构以及编译的时候 grub 配置项。

[debiansid]

@lisaac 试过了 还是驱动吧 不能启动时 系统没认出 sda

[lisaac]

@debiansid CF 卡应该是 usb 驱动吧， xhci-hcd ehci-hcd

[debiansid]

@lisaac 插在主板背面的 sata 的应该是
