It seems the nanopi core/core2 now have 8/16/32 emmc options and the nanopi neo/neo2 images dont have emmc support in them . We need to get emmc support added . the plus2 will not boot the core2 . it locks up .

I have the board and have tried starting work on it. but the dtb src seems to be a issue

Here is a easier way to do gpio setup/teardown To setup , chmod +x armbian_gpio_up and gpio_down put the scripts armbian_gpio_up and armbian_gpio_down in /usr/sbin put armbian_gpio.conf /etc In the armbian_gpio.conf you just have to put the pin numbers as follows # Space separated list of GPIO pins that point IN and have an # Active HIGH state (3.3v = ON, 0v = OFF) GPIO_IN_HIGH="10 12 27" on the lines you need for high/low/in/out. Then run armbian_gpio_up to setup the gpio pins, and run armbian_gpio_down to teardown the gpio. Then run armbian_gpio_up to setup the gpio pins, and run armbian_gpio_down to teardown the gpio. armbian_gpio_up armbian_gpio.conf armbian_gpio_down whiptail_gpio_config.sh

Having run the 4.11 kernel on the new img igor generated for the neo2 . the kernel needs some tuning as the neo2 is running hot. compaired to the 3.x kernel . if there are some pointers where to look please point me and and where the armbian keeps its kernelsrc

I have tested on both the neo 1.3 and the neo 2 with all the wifi adapters klisted as working on armbian and it fails on the neo/neo2 we get kernel crashes. and reboots. this happens even if you boot and then plug on the wifi adapter. . I will attempt to get a log for you

Is armbian dropping debian for devices like the neo and neo2 ? we need debian . we dont use ubuntu ....
