在厌倦了双启动 chrubuntu/chromeos 之后，我决定在基于 XE303C12 ARM 的三星 chromebook 上安装 Arch Linux。我按照这里的说明操作：https ://wiki.archlinux.org/index.php/Samsung_Chromebook_%28ARM%29
我成功地将未经验证的 u-boot 刷入 SPI 闪存，并按照此处的说明，用从 archlinuxarm.org 获得的 arch linux 内核和 rootfs 替换了内部 SSD 上的所有内容：http: //archlinuxarm.org/platforms/armv7 /samsung/samsung-chromebook#qt-platform_tabs-ui-tabs2
在使用 u-boot 提示符后，我的系统成功启动到 SSD 上的 arch linux。但是，我无法再建立 wifi 连接。

这看起来是相关部分：
[ 64.648157] mwifiex_sdio mmc2:0001:1: Failed to get firmware mrvl/sd8797_uapsta.bin
sd8797_uapsta.bin 实际上存在于 /lib/firmware/mvrl/sd8797_uapsta.bin
我不知道 mwifiex_sdio 驱动程序是如何工作的，而且谷歌搜索似乎只是让我在兔子洞里走得更远。我会提到，我确实设法在双启动环境中通过 sd 卡的网络连接运行 arch（使用上面第二个链接中的说明），但那是在我将 nv_uboot 闪存到 SPI 闪存之前。据我了解，SPI flash 中的签名 u-boot 之前加载了驻留在 sd 卡上的未经验证的 u-boot，该 u-boot 又加载了 arch 内核。使用我根据上面第一个链接设置的系统，SPI flash 中的 nv_uboot 直接加载内核，无需中间引导加载程序。我最好的猜测是这个中间阶段的一些不应该被跳过的东西。
lsblk 的输出以获得良好的衡量标准：

-mmcblk0p2 179:2 0 14.7G 0 part /
mmcblk0p1 包含 arch 内核
mmcblk0p2 是 rootfs
那么有人对调试这个系统有什么建议吗？如何确保 mwifiex_sdio 找到它的固件？
对不起，如果我不够详细，这是我第一次在这里发帖。如果您需要查看更多输出，请告诉我，我会发布它们。
