  1. I have armbian 5.65 ( kernel 4.14.78-sunxi) on BPI M2 Plus

    I can enable hotspot using armbian-config but when connect to AP, no internet access

    Is there any setting missing here??

    I gave you new link few posts back. This work has been done about 2 years ago, so I forgot many details. It seems CONFIG_VIDEO_DE2=y is enough to enable driver, TV plug-in is auto-detected at boot only and only PAL is supported. It seems that that branch also doesn't have simplefb support.

     

    I don't know when I will get back to this, since I'm busy with Linux kernel stuff, mostly Cedrus and DE2 driver.

     

    I modify all u-boot source file mark with "sunxi: video: Add H3/H5 TV out driver"

    Also I make sure 'CONFIG_VIDEO_DE2=y' is there in .config

    u-boot compilation is successful but still no TVE out

    looking at kern.log, kernel is doing something related to TVE, but I don't understand 

    Can you give some highlight what happenings?

    Attached is kern.log and debug

    Hint on how to maybe fix overscanning:

     

    set a smaller resolution by kernel parameter (example):

    
    video=Composite-1:720x480

     

    Move the picture using this tool: https://projects.nwrk.biz/projects/allwinner-tvout

     

    This is a similar approach like I did on legacy kernel (read here)

    how do you set kernel parameter 'video=Composite-1:720x480' for mainline kernel ?

    @zador,

     

    I just added support for TV out, PAL and NTSC standard. Do you think that it is interesting enough to include in Armbian? Maybe for OPi0?

     

    https://github.com/jernejsk/u-boot/tree/h3_hdmi_tv_v1

     

    You have to include "CONFIG_VIDEO_COMPOSITE=y" in defconfig. PAL is selected by default and can be overriden by environment variable.

     

    @jernej you're saying it needs CONFIG_VIDEO_COMPOSITE=y in defconfig?

    I add this in Sinovoip_BPI_M2_Plus_defconfig but I don't see it include CONFIG_VIDEO_COMPOSITE=y  in .config while u-boot compile. Also that link you provide no longer working. Any more details?

    Could you please tell how how did you compile snd-soc-pcm5102a.ko?

    On my NanoPi Neo I

    - changed the .dtb for the Neo

    - did armbian-add-overlay ./sun8i-h3-I2S-out.dts

    - now have in armbianEnv.txt: 

       user_overlays=sun8i-h3-I2S-out

    - lsmod|grep i2s
         sun4i_i2s              16384  0
         snd_soc_core          118784  2 sun4i_i2s,sun8i_codec_analog
         snd_pcm                69632  3 sun4i_i2s,snd_pcm_dmaengine,snd_soc_core  

     

    I think I do only need the .ko in my system - compiled for

    ARMBIAN 5.65 stable Debian GNU/Linux 9 (stretch) 4.14.84-sunxi

    Linux npi-neo 4.14.84-sunxi #3 SMP Sat Dec 1 07:18:41 CET 2018 armv7l GNU/Linux

     

    I did try to see it in "only U-Boot/kernel" in the armbian-build-system - BUT failed :(
    I did see that kernel-menuconfig, but dont know what to do with it and the patch:

     

     

    For the Neo I have the PCM5102A-Hat from FriendlyARM

    https://www.friendlyarm.com/index.php?route=product/product&product_id=169

    and it is/was running fine with legacy kernel 3.4:

     

     

    NanoPi_PCM5102A.jpg

    You have to modify config PCM5102A like below on  cache\source\linux-mainline\v4.14.84\sound\soc\codecs\Kconfig

    config SND_SOC_PCM5102A
        tristate "Texas Instruments PCM5102A CODEC - I2S"

    then replace config-default.conf with attached

    With this conf, script compilation will stop to overwrite kernel source to build patch

    At that time, overwrite original Kconfig with the one you modified above

    Then script compilation will stop again to ask whether you want to add pcm5102a to compile

    Default is N, so you need to enter m for module compilation

    Yeah!! I managed to fix the overscanning issue!  (Credits go to this guy here for pointing me to the right direction!).

     

    All in all my Picture was Overscanning 20 px on every edge.

     

    At first I changed my resolution from the detected 720x576 to 680x536 (2 * -20 px = -40 px) in the script.bin. This results in an visible edge at the bottom of the screen and an visible edge on the right hand side (with a small black border!).

    
    $ bin2fex /boot/script.bin ~/script.fex
    $ nano ~/script.fex
    
    find these lines:
    fb0_width = 0
    fb0_height = 0
    
    and change them to:
    fb0_width = 680
    fb0_height = 536
    
    then:
    $ fex2bin ~/script.fex ~/script.bin
    $ sudo cp ~/script.bin /boot
    $ sudo reboot

     

    Now the picture needs to be moved down and to the right by 40px to be fully visible!

     

    Next I needed to manipulate TV ENCODER RE-SYNC PARAMETERS REGISTER of the H2+ SoC. For this I used a little tool called devmem2 which helped me to directly read and write to the memory, and thus allowed me to manipulate the H2+ registers!

     

    devmem2 can be installed by using following commands:

    
    wget http://free-electrons.com/pub/mirror/devmem2.c
    gcc ./devmem2.c
    sudo mv ./a.out /usr/local/bin/devmem2

     

    After Installing devmem2 I was able to shift the picture by manipulating the value on following Address: 0x01E00130! (=TV ENCODER RE-SYNC PARAMETERS REGISTER, this may differ depending on your SoC, check the Datasheet!)

    First I read back the actual value (so I could revert back changes in case I messed anything up!):

     

    
    $ sudo devmem2 0x01E00130 
    /dev/mem opened.
    Memory mapped at address 0xb6f0d000.
    Value at address 0x1E00130 (0xb6f0d130): 0x3005000A

    Now I was able to move the picture by writing a custom value to the register according to the R40 Datasheet: 

     

    TV ENCODER RE-SYNC PARAMETERS REGISTER Datasheet entry:

      Reveal hidden contents

    Re-Sync.png

     

    Here is how I calculated this value with the help of the Datasheet:

    31 ... Re-Sync Field => 0b 

    30 ... Re-Sync Disable => 0b

    29:27 ... not used => 000b

    26:16 ... Vertical => 40d px => 0000101000b

    15:11 ... not used => 00000b

    10:0 ... Horizontal => 40d px => 0000101000b

     

    All in All: 000000000101000000000000101000b => 0x00140028

    So I used this command to set my display:

    
    $ sudo devmem2 0x01E00130 w 0x00140028

    EDIT: I created a small tool which does the work above for you ;)

     

    Finally I saved the command above in my rc.local file to shift the picture during boot.

    
    $ sudo nano /etc/rc.local
    
    paste following line:
    devmem2 0x01E00130 w 0x00140028

    This is a dirty workaround and should be fixed within the driver!

    Hope this helps to correct your overscanning issues! This should also work with many other Allwinner based Boards. I read that some Bananapi users had a pretty similar problem with overscanning on AV out.

     

    I compile devmem2 but cannot write to register. It shows register value still the same

    I have Banana Pi M2+ which has allwinner H3

    Just an update, X installs and runs fine on the Orange PI Zero using my patch.  HOWTO:

     

    Install a desktop using

    
    sudo tasksel


    after its all finished properly, reboot.  You will then get this:
    https://imgur.com/a/seu9t

    if you want to change video mode, you can do it with xrandr like this:

    
    DISPLAY=:0 xrandr --output Composite-1 --mode NTSC
    DISPLAY=:0 xrandr --output Composite-1 --mode PAL

    You only need the "DISPLAY=:0" if you are doing the mode setting from a ssh terminal.

    Supposedly xrandr can scale the desktop and move it around (which could help with the overcan problem) but i couldn't get it to work in the 5 minutes I allocated to testing it.

     

    how to set NTSC mode if I don't have X11 ??

  11. anybody manage to get bluetooth on BPI-M2+ working?

    I change dts and already enable uart1 and hook cts_rts but get init time out

  12. @Igor for improvement, you might want to create patch on sun4i-i2s.c and include in armbian kernel

    this code will add 20bit and 24bit audio resolution

    here is the code https://github.com/dony71/linux-sunxi/blob/sunxi-wip/sound/soc/sunxi/sun4i-i2s.c

    also i have example overlay for allwinner H3 for pcm5102a codec here https://github.com/dony71/linux-sunxi/blob/sunxi-wip/arch/arm/boot/dts/sun8i-h3-I2S-master.dts

    This is not possible with your setup, based on the information in the A20 i2s documentation. From what I remember when I worked with the PCM5102A then I needed to provide a 32bit sample(this has also been seen with the HDMI audio), do you have these tdm settings in your dts/overlay?

    https://github.com/codekipper/linux-sunxi/commit/977b5838a184350fa8e794420a947d31d81c2e54#diff-9fb7f343370c25c84e919e9a8e392b74R200

    I checked your wip i2s driver code with my hardware and simple codec driver for my clock board. In function sun4i_i2s_set_clk_rate calculates lrck value as

    
    (clk_rate / rate / oversample_rate)*word_size

    and we have, eg (22579200 / 44100 / 128) * 16 = 64 of BCLKs within each channel. But in stereo i2s mode lrck value must be equal slot width. In stable version lrck fixed and equal 32. After I replace calculated value lrck to fixed 32 I successfully played 16/24 bit sample.

    Well, I manage to compile pcm5102a for kernel 4.14.78

    I wonder why armbian kernel never include this in Kconfig, so it show none in menuconfig

    I have to modify Kconfig on-the-fly during compilation, since .config will be overwritten at some point in compilation

    Implementing  "CONFIG_SND_SOC_PCM5102A=m" in userpatches/linux-sunxi-next.config also doesn't work
     

    I try to play some music  

    mclk-fs = 128 in overlay and this will give default 96K sampling rate 

    playing 96K music has no issue, but when i try playing 44.1K music, the music speed is double faster

    anybody knows what could be the problem? maybe some setting in pulseaudio?
