This prevents extroot configurations from working as overlayfs is mounted before USB device can be powered on. This commit fixes this by enabling USB in devicetree. Related discussion links: - https://forum.openwrt.org/t/usb-power-is-off-on-boot/229007 --- Extroot configuration requires the USB to be powered on before preinit_main/80_mount_root. Probably the simplest approach is to enable it in the devicetree. Another approach would be to add a script into /lib/preinit that will power on USB via /sys/class/gpio/usb-power/value E.g. cat /lib/preinit/79_power_on_usb do_power_on_usb(){ echo '1' > /sys/class/gpio/usb-power/value } boot_hook_add preinit_main do_power_on_usb Signed-off-by: Valeriy Manzhos Link: https://github.com/openwrt/openwrt/pull/19149 Signed-off-by: Hauke Mehrtens --- diff --git a/target/linux/ath79/dts/qca9558_mikrotik_routerboard-96x.dtsi b/target/linux/ath79/dts/qca9558_mikrotik_routerboard-96x.dtsi index 684ca8632a4..4e219d167c1 100644 --- a/target/linux/ath79/dts/qca9558_mikrotik_routerboard-96x.dtsi +++ b/target/linux/ath79/dts/qca9558_mikrotik_routerboard-96x.dtsi @@ -44,7 +44,7 @@ usb_power { gpio-export,name = "usb-power"; - gpio-export,output = <0>; + gpio-export,output = <1>; gpios = <&gpio 13 GPIO_ACTIVE_HIGH>; }; };
