    H2: Sunvell R69 Android TV Box (AliExpress)

    Looks like that there is a new board version of this TV Box and unfortunately the Armbian images existing for R69 didn´t work for me. I have tested the images from Google Drive: Armbian 5.59 and 5.46 without success, the same for RetroOrangePi R69 image. I already change SD-Card and power supply, but since this setup works for old R69/PCB version (I have both) I believe that the problem is related with boot process (uboot, fex config, kernel, etc) or other hardware configuration. To understand better the problem I disassembly the device and connect the UART port. From the UART shell I can get some information: - Check Android ROM existing on board have and have U-Boot 2014.07 (May 04 2018 - 09:38:22) and kernel version 4.4.55 - Check the processor info using cat /proc/cpuinfo and confirm that is a Allwinner H2 processor. When I try to boot using the SD-Card and Armbian image only only few information is displayed on shell: U-Boot SPL 2018.05-armbian (Aug 20 2018 - 12:41:20 +0000) DRAM: 0 MiB ### ERROR ### Please RESET the board ### If I insert the SD-Card after android boot the sd-card is recognized, so don´t look and hardware problem on sd-card or power supply. Anyone could give a direction how to get Armbian images working on this new PCB board? Photos of new board and complete boot logs on link bellow. New PCB version is 2.0 from 2018-04-08 https://www.dropbox.com/sh/z0dosazsfkfsifn/AAA_uYLTipqKTRX_e0MYNxDRa?dl=0
