I have some questions. 1. I cannot shutdown my system. : I install android x86 6.0-R3. When I push ACPI power button, pop up window said shutdown. When I click that Icon, I cannot shutdown my system. It loops said it is trying to shut off(in my language). 5 min, 10min, It still trying to shutting down. 2. Wi-Fi / BT not work. I think, next link is same issue. https://www.udoo.org/forum/threads/udoo-x86-android-not-seeing-wifi-bluetooth-module.6956/ 3. I want to use USB GPS(Serial) and USB LTE modem(Huawei E3372). I insert USB to my Udoo x86, kernel log said, device descriptor read/64, error -71 So, I decide to check kernel config. I download android x86 and check their config. $ . build/envsetup.sh $ export ARCH=x86 $ lunch android_x86-eng $ make -C kernel KCONFIG_CONFIG=kernel/arch/x86/configs/android-x86_64_defconfig O=/work/config/.config xconfig First, I check drivers related to GPS(USB SERIAL) and WIFI/BT. pl2303 : M iwlwifi : M I think, setting of kernel is correct. So, I decide stop checking it. Please help me how to solve these problems. Thank you for reading.
