  1. I have a TV box with S905L3B (dtb file in android system is named gxlx2_p291_1g.dtb). However, I can't find a suitable dtb file for Armbian. So I wonder if I or someone else can adjust or modify the dtb file to boot an Armbian system if I have the gxlx2_p291_1g.dtb and gxlx2_p291_1g.dts files from the Android system(4.4.2)?
  2. I have a problem. I try to boot "Armbian_5.67_Aml-s9xxx_Debian_stretch_default_4.19.7_20181228.img.xz" on a S905L 3B TV box, the ditb file use the default one (it works for S905L). I use a TTL to USB device to check signal, and it started to login stage. However, the LAN port and HDMI port seem not work, as I can' t use SSH to connect to Armbian and I can't see any thing on the screen. So I guess maybe the dtb file is not suitable, and there may not be a suitable dtb for S905L3B. Could I modfiy a dtb file based on the S905L dtb file and the dtb file from the Andriod system in the S905L 3B TV box?

  4. I have a problem. “ddbr” can not make a backup of a andriod system in a Amlogic S905 TV box with a NAND flash, see this link for more details. When I use 'ddbr' in an Ambian system booted by USB drive, it shows below: root@SumavisionQ5:~# ddbr DO YOU WANT TO BACKUP OR RESTORE ? BACKUP=(b) RESTORE=(r) b UNABLE TO FIND ANY EMMC OR SD DRIVES ON THIS SYSTEM!!! I think someone else must have the same problem. Can we make an improvement of 'ddbr' , so that it can be used for a NAND flash.
  5. Hello, everyone! I have an S905M device (Sumavision Q5, RAM:1G, ROM:8G), I made a bootable USB with an Armbian image( ARMBIAN 5.44 user-built Ubuntu 18.04.5 LTS 3.14.29, use gxbb_p201.dtb file ) . I want to use "ddbr" then “b” to make a backup of the EMMC. However, root@SumavisionQ5:~# ddbr DO YOU WANT TO BACKUP OR RESTORE ? BACKUP=(b) RESTORE=(r) b UNABLE TO FIND ANY EMMC OR SD DRIVES ON THIS SYSTEM!!! then I use command "lsblk", I found all partitions(cache, params, ... , data) of the internal storage (8G ROM) for andriod system are treated as seperated disks as shown below: root@SumavisionQ5:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 1 14.9G 0 disk |-sda1 8:1 1 128M 0 part /boot `-sda2 8:2 1 14.6G 0 part / cache 250:0 0 512M 0 disk params 250:1 0 64M 0 disk logo 250:2 0 32M 0 disk recovery 250:3 0 32M 0 disk rsv 250:4 0 8M 0 disk tee 250:5 0 8M 0 disk crypt 250:6 0 32M 0 disk misc 250:7 0 32M 0 disk instaboot 250:8 0 512M 0 disk boot 250:9 0 32M 0 disk system 250:10 0 1G 0 disk data 250:11 0 4.9G 0 disk zram0 253:0 0 100.9M 0 disk [SWAP] zram1 253:1 0 100.9M 0 disk [SWAP] zram2 253:2 0 100.9M 0 disk [SWAP] zram3 253:3 0 100.9M 0 disk [SWAP] use armbianmonitor -u, a detail info is uploaded in From that, I find something the 8G ROM is in NAND instead of in EMMC : [ 6.263857] nandphy: Nand PHY Ver:XXX.XXX.001.0006 (c) 2013 Amlogic Inc.

Could command “ddbr” make a backup of NAND flash? OK! As far as I know,command “ddbr” can not make a backup of a andriod system in NAND flash. ________________________________________ Background................................................... I also have a device (Tianyi, TY1208-Z, RAM:1G, ROM:8G) with S905L, and I have successfully made a backup file of EMMC. The EMMC is normally recognised as shown below: root@aml:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT mmcblk0 179:0 0 1.9G 0 disk |-mmcblk0p1 179:1 0 128M 0 part `-mmcblk0p2 179:2 0 1.7G 0 part mmcblk1 179:32 0 7.3G 0 disk |-mmcblk1p1 179:33 0 122M 0 part /boot `-mmcblk1p2 179:34 0 6.5G 0 part / mmcblk1boot0 179:64 0 4M 1 disk mmcblk1boot1 179:96 0 4M 1 disk zram0 253:0 0 50M 0 disk /var/log zram1 253:1 0 417M 0 disk [SWAP]
  6. Yes, you can make a bootable USB with an Armbian image . Use "ddbr" then “b” to make a backup of the internal EMMC. The backup file will be in /ddbr of the USB device. Restore that image file with "ddbr" then "r" to another device with same hardwares.
