    How to patch U-boot ?

    Thanks for the tip. The point is : I would like to make change to the U-boot ( /home/hanguofu/Build-Armbian/cache/sources/u-boot-aml-s9xxx) instead of kernel ( /home/hanguofu/Build-Armbian/cache/sources/LINUX_DEFAULT/20180925 ). How to tell the tool to patch U-boot instead of the kernel please ? I didnot find out such an option or compile switch.

    How to patch U-boot ?

    I run Armbian tool ( checked out from https://github.com/150balbes/Build-Armbian )with command ./compile.sh CREATE_PATCHES="yes" , but only see the request for patch the kernel : [ warn ] Make your changes in this directory: [ /home/hanguofu/Build-Armbian/cache/sources/LINUX_DEFAULT/20180925 ] [ warn ] Press <Enter> after you are done [ waiting ] I would like to patch the U-boot ( u-boot-aml-s9xxx ) instead of kernel . Should I manually add the patch to the userpatches/u-boot directory for my aml-s9xxx board ?
  3. I installed Armbian_5.60_Aml-s9xxx_Ubuntu_xenial_default_4.18.7 to the EMMC of my s905x TV Box , so far so good . Yesterday I trimmed some drivers and built the kernel successfully . The following packages are generated with armbian build tool : linux-dtb-aml-s9xxx_5.60_arm64.deb linux-headers-aml-s9xxx_5.60_arm64.deb linux-libc-dev-aml-s9xxx_5.60_arm64.deb linux-image-aml-s9xxx_5.60_arm64.deb linux-source-default-aml-s9xxx_5.60_all.deb I am going to ssh into my box and run "dpkg -i " commands to update kernel . Is it safe to do so while Armbian is running ?

    Armbian for Amlogic S9xxx kernel 4.1x (>= ver 5.55)

    I put the img. Armbian_5.59_Aml-s9xxx_Ubuntu_xenial_default_4.18.0_20180823.img into a usb disc. and boot it successfully with my TV box. I havenot flashed the emmc yet . Another word , I played with Armbian installed at the U-disc. However , when I tried to upload/download files to/from the box with tool "Xftp 5" ( from NetSarang ) , the tool failed to connected to the box. The box and my pc are in the same local network ( 192.168.0.xxx ) Of course , the ssh service is good and I can log into the box with tool "Xshell 5". Is the ftp service not avail. at the img. ?
  5. I am trying to build 150balbes/Build-Armbian at my Ubuntu18 PC . However , the download process of toolchains are very slow. I had already spent most of the day in it. Unfortunatly , some of the toolchains was downloaded with warnings : [ warn ] Verification failed Could you please tell me the list of all needed toolchains and its source ? I will try to downlaod them in another way. Thanks ! Guofu Han
  6. Since there is a well-known security issue at s905(x) SOCs : https://fredericb.info/2016/10/amlogic-s905-soc-bypassing-not-so.html Is it possible to disable serial console at s905 u-boot ? Does the setting at device tree apply to kernel only or both kernel and u-boot drivers ? Regards ! Guofu Han
  7. I am referring to s905(x) series SOCs. Is it possible to create a cryptpasswd at encrypted OTP and use it to unlock root file system on boot ? If not , is it possible to use a security chipset such as ATSHA204 / DX81C04 / ZW30I8 / SMEC98SP to feed s905(x) the key ? Regards ! GuoFu Han

    ARMBIAN for Amlogic S905 and S905X (ver 5.44 =<)

    Yes . You are right . I did not notice s905x is a 64-bit SOC. Cheer ~~~

    ARMBIAN for Amlogic S905 and S905X (ver 5.44 =<)

    arch ( ARM or ARM64 ) problem : Hi , All : I installed Armbian_5.41.1_S9xxx_Ubuntu_xenial_3.14.29_mate_20180421.img at the SD card for my s905x TV box and it seems O.K. Now I tried to cross compile an application at my Ubuntu PC for this lovely device. The first problem I encountered is the choice of arch. I worked out a 32-bit arm application ( target arch : ARM) with the cross compile tool . The generated binary is : hello-world : ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, not stripped Unfortunately , I did not find the needed interpreter at the tv box . The only interpreter I found at the img at the SD card is : /lib/ld-linux-aarch64.so.1 -> aarch64-linux-gnu/ld-2.23.so Does it mean that the img is for ARM64 arch ? Is there a ld-linux-armhf interpreter at the image ?

    ARMBIAN for Amlogic S905 and S905X (ver 5.44 =<)

    Yes . You got it . I only have a traditional tv set with cvbs ( composite or AV ) input and a computer monitor with VGA input.

    ARMBIAN for Amlogic S905 and S905X (ver 5.44 =<)

    Sorry for my question if it had been asked : is there any Ubuntu img available for MXQ PRO+ 4K ( s905x , 2G/16G ) with cvbs compatibility ? I donot have a hdmi monitor and I would like to try Ubuntu on my tv box. I tried multi-boot with Armbian_5.44_S9xxx_Ubuntu_xenial_3.14.29_server_20180515.img at my sd card , but there is no av ( cvbs ) output at all. I am not sure if the dtb.img is suitable for my tv box ( I tried several dtb files ) or the armbian Ubuntu img does not support cvsb output at all ?
  12. I think webrtc is a very interesting feature for such devices. Unfortunately , I only saw a drive ( UV4L : https://www.raspberrypi.org/forums/viewtopic.php?f=43&t=105019) for Raspberry Pi2/Pi3 in linux. Does somebody here have any idea to cross-compile native webrtc source code for such a device ? Regards ! GuoFu Han
