  • Tanix TX6

    Quote from ukmark62

    One more thing I noticed was that the RAM in Kodi shows as 3gb. I remember you saying there was some limit on RAM, but there was a hack to get it to show/use 4gb RAM??

    H6 is only capable to address 3GiB of RAM. It has 32-bit address space and lower 1 GiB is reserved for memory mapped peripherals. Take another look at serial output. SPL DRAM driver will correctly report 4 GiB of RAM, because so much of RAM is physically present. However, U-Boot will report 3 GiB of RAM, because so much can be really used.

    No one really knows if there is a way to use that 1 GiB of RAM. It certainly can't be directly addressed.

    ukmark62 please test this image: libreelec-h6.arm-9.1-devel-20190615175620-0b86f08-tanix_tx6.img.gz

    It should have proper U-Boot already, so you just burn it on SD card and try right away. I also fixed resolution detection and HDMI audio. STB has additional pin which has to be enabled in order to correctly read EDID.

    USB3 also doesn't work yet. Anyway, if this works as intended so far, I'll stop right here until I receive my box.

    If you are curious, I uploaded LibreELEC changes here: Commits · jernejsk/LibreELEC.tv · GitHub

    1 Display resolution is limited to 1024x768 and below. Only 60hz frequencies available

    2 No sound (I notice on initial bootup that a "FAILED:Pulse Audio Driver not installed" message showed up. However it has not shown up since I've rebooted again. However, still no audio.

    I'll fix this with next image, which will also have proper U-Boot included.

    Image will have at least two issues - no wifi and no ethernet. I will fix ethernet after I receive my box, but wifi will be hard. Apparently, there are two variants of the box. One with Realtek SDIO wifi module with no open source drivers and another one with PCIE wifi module. PCIE on H6 is quirky and driver may never be properly included in mainline Linux.

    ukmark62 That seems fine.

    Are following lines continuously being repeated or they stop after some time?

    [  OK  ] Started Kodi Media Center.

    [  OK  ] Stopped Kodi Media Center.

    If not, are you sure you correctly identified TX pin?

    One thing you can try at this point is to recreate SD card. Burn image again, overwrite U-Boot and fix DT before first boot. It's possible that something was stored at first boot which doesn't match anymore, like board name.

    ukmark62 Edit extlinux/extlinux.conf again and remove console=tty1 from append line. That way you will get terminal on serial console. Please copy and paste output of dmesg.

    BTW, please use pastebin for it or at least use spoiler tag.

    Write the Orange Pi 3 image to sd card (using rufus), then "dd" only the u-boot-sunxi-with-spl.bin to same sd card?

    In general, yes. How you write image to SD card is up to you. I use "dd" for everything, but that is not the best method.

    Which dtb should I use or is that irrelevant? Thx

    In this case you'll use orangepi3 DT, which of course is not optimal, but it should show some signs of life. Later, we should write Tanix TX6 specific DT.

    ukmark62 Great! That means DDR3 initialization works! Still some work to do to put everything into appropriate form to be sent to U-Boot mailing list, but first Tanix TX6 LE image could be available next week.

    BTW, you may experiment now by taking existing OrangePi 3 LE image and flash this U-Boot binary over. It won't work 100% correctly and there will be errors reported, but it may work.
