Я решил установить Arch Linux на свой хромбук Samsung XE303C12 на базе ARM после того, как устал от двойной загрузки chrubuntu/chromeos. Я следовал инструкциям здесь: https://wiki.archlinux.org/index.php/Samsung_Chromebook_%28ARM%29
Я успешно прошил непроверенный u-boot на флэш-память SPI и заменил все на внутреннем SSD на ядро arch linux и rootfs, полученные с archlinuxarm.org, в соответствии с инструкциями здесь: http://archlinuxarm.org/platforms/armv7/samsung/samsung-chromebook#qt-platform_tabs-ui-tabs2
После игры с приглашением u-boot моя система успешно загружается в Arch Linux на SSD. Однако я больше не могу установить соединение Wi-Fi.

[ 64.648157] mwifiex_sdio mmc2:0001:1: Failed to get firmware mrvl/sd8797_uapsta.bin
sd8797_uapsta.bin действительно существует в /lib/firmware/mvrl/sd8797_uapsta.bin
Я понятия не имею, как работает драйвер mwifiex_sdio, и гугление, похоже, просто уводит меня дальше в кроличью нору. Я упомяну, что мне удалось запустить Arch с сетевым подключением в среде с двойной загрузкой с SD-карты (используя инструкции из 2-й ссылки выше), но это было до того, как я прошил nv_uboot на флэш-память SPI. Насколько я понимаю, подписанный u-boot во флэш-памяти SPI ранее загружал непроверенный u-boot, находящийся на SD-карте, который, в свою очередь, загружал ядро арки. В системе, которую я установил по первой ссылке выше, nv_uboot во флэш-памяти SPI напрямую загружает ядро без необходимости использования промежуточного загрузчика. Мое лучшее предположение состоит в том, что что-то из этого промежуточного этапа пропускается, чего не должно быть.
Вывод lsblk на всякий случай:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 1 1.9G 0 disk
-sda1 8:1 1 1.9G 0 part /mnt
mmcblk0boot0 179:16 0 2M 1 disk
mmcblk0boot1 179:32 0 2M 1 disk
mmcblk0 179:0 0 14.7G 0 disk
|-mmcblk0p1 179:1 0 16M 0 part
-mmcblk0p2 179:2 0 14.7G 0 part /
mmcblk0p1 содержит ядро арки
mmcblk0p2 — это корневая файловая система.
Итак, есть ли у кого-нибудь предложения по отладке этой системы? Как сделать так, чтобы mwifiex_sdio находил свою прошивку?
Извините, если я недостаточно многословен, я впервые пишу здесь. Дайте мне знать, если вам нужно увидеть какие-либо еще результаты, я опубликую их.
