    RFCOMM TTY support not available

    in Tinkerboard

    Posted


    Hi 

    Replying to myself to keeping trace and maybe help someone. So after building a new kernel with CONFIG_BT_RFCOMM_TTY=Y (using a VM), I installed the new packages using build debs :

     

    dpkg -i armbian-config_19.11.4_all.deb
    dpkg -i armbian-firmware_19.11.4_all.deb
    dpkg -i linux-dtb-current-rockchip_19.11.4_armhf.deb
    dpkg -i linux-image-current-rockchip_19.11.4_armhf.deb

     

    So now my tinker uses : Ubuntu Bionic with Armbian Linux 5.3.18-rockchip

     

    and RFCOMM TTY is working

    Hi,

     

    It seems I'm not the only one : https://forum.radxa.com/t/rfcomm-failures-in-ubuntu-server-image-and-debian-desktop-image/375

     

    If linux-rockchip64-current.config is the right configuration for my Tinker Board, then RFCOMM is set to  # CONFIG_BT_RFCOMM is not set

     

    Trying to buil da new kernel 

     

    root@armbuild:~/build# ./compile.sh
    [ o.k. ] Create example config file using template [ config-default.conf ]
    [ o.k. ] Using config file [ /root/build/userpatches/config-example.conf ]

    Dear all,

     

    I'm looking for help on having  RFCOMM TTY working on a Tinker Board S. Any help will be welcome !!

     

    Using : Ubuntu Bionic with Armbian Linux 4.19.69-rockchip

    # uname -a
    Linux astrotinker 4.19.69-rockchip #5.95 SMP PREEMPT Mon Sep 2 07:34:36 CEST 2019 armv7l armv7l armv7l GNU/Linux


    I'm trying to have rfcomm tty working with a bt HC-05 dongle, but RFCOMM TTY seems not to be available. The BT HC-05 is well reconized and connected:

    Properly powering the Tinkerboard

    Hi

    According to this thread on Tinker Board forum https://tinkerboarding.co.uk/forum/thread-1877-post-7965.html#pid7965  

    Hi, maniolias
    Since there is a bug on V2.0.4 u-boot, it will cause un-boot when powering by 40 pin GPIO, it needs the below commit to fix which is included 
    in the v2.0.5 u-boot.
    https://github.com/TinkerBoard/debian_u-boot/commit/879646d1d6c714335eb065a404ae033261236213
    So please use the v2.0.5 u-boot

    a fix is needed for the Tinker OS.

    Is this fix:

    https://github.com/TinkerBoard/debian_u-boot/commit/879646d1d6c714335eb065a404ae033261236213

    applied (appliable ?) to Armbian Stretch or Bionic ?

    hmm... 

    3A should be more than enough... Maybe it doesn't deliver what it promised or.. Voltage is lower than 5V? Did you check it with a multimeter 'under load' (means during the time it 'should' power your SBC)?

    Well, I tryed with a AC/DC 5V 3A power, which voltage is correct,  connected on pins 4 (vcc) and 6 (gnd)  and the board does not boot !? It seems Tinker Board S can not be powered from the GPIO anymore ?

    Just  made a support request to Asus

    Hi everyone !

    First post here, glad to meet you.

    I'm trying to powering up a Tinker Board S using pin 1 and 5 with a step down buck convertor. The main power is coming  from a 12v ac/dc convertor connected to the dc/dc buck convertor set to 5V and 3A. The card just looping trying to boot. Did anyone experience this issue ? Do you have any advice on what step down buck convertor tu use ?

    Thanks
