Is it this one? https://github.com/150balbes/Amlogic_s905-kernel/blob/master/arch/arm64/boot/dts/amlogic/meson-gxl-s905d-ki-pro.dts if so it seems it just adds the dvb hardware to meson-gxl-s905d-p230 and that didn't work when I tried it, so I doubt it will work but I'd be delighted to be proven wrong.

the dtb you mention are only available for kernel 3.14, they won't work for any later kernel

Because there is no dtb that works for the KI pro. The dtb for 3.14 cannot be used since the format changed.

@erbas I didn't pursue this further. I'm currently running libreelec but with kernel 3.14, as it seems nobody has a working dtb for newer kernels and I'm not able to write one. With libreelec the dvb driver more or less works but worse than under android (with android I can tune both dvb-s/s2 muxes as well as dvb-t, with libreelec I have more difficulty tuning some dvb-s/s2 muxes and cannot tune dvb-t at all). Perhaps later I'll try armbian again on this box, but for the time being libreelec it is.

Just found this thread that explains the problem and the possible solutions

Do you think that blocking the update of systemd will solve the problem?

Being hit by this issue today (though I'm not sure since other network services are starting normally and I don't have currently access to a console), I wonder why systemd is being offered as an upgrade if it's going to cause this problem.

I'm using this one: https://github.com/aircrack-ng/rtl8812au/tree/v5.1.5 (other branches gave poorer performance). I think I tried various repositories before settling on this one.

I have a stick based on that chipset. I'm not using it with armbian (so the chosen driver there may be better) but it's not without issues: since it's not been mainlined (yet?) on a desktop (kubuntu) distribution you have to chase a driver (there are several variations, some of them working better than others) and even when you find the "correct" one there are still issues: sometimes I have to unplug and re-plug the stick to get a connection, sometimes, when it doesn't connect, it gets really hot. When it works it works fine though.

@balbes150 do you know why such a simple module doesn't work (and messes up the kernel so badly that afterwards lsmod hangs forever)? A mismatch between the compiler used to compile the kernel and the one installed with armbian perhaps? If so, what compiler should I use to compile the module?

I also tried to take the configuration of the running kernel from /proc/config.gz (which is different from the one contained in the deb) with the same result

Actually it doesn't seem to be OK. Before trying the lengthy compilation of the dvb modules needed, I just tried with the hello module and: luca@aml:~/hello$ sudo insmod hello.ko [sudo] password for luca: Segmentation fault relevant lines from dmesg [ 127.554547] EBB: Hello world from the BBB LKM!

I see those debs are version 5.41, the image I'm using has 5.44. I suppose that's OK (the kernel is the same version).

Ok, so where do I find a crash course on how to rewrite the dts based on the information contained in the old one? (if that makes sense)

Alternatively, where do I find the kernel headers for 3.14.29? I need to compile the dvb drivers and the only packages with 3.14.29 are: luca@aml:~$ apt-cache search 3.14.29 linux-dtb-aml-s9xxx - Linux DTB, version 3.14.29 linux-image-aml-s9xxx - Linux kernel, version 3.14.29 No linux headers.

OK, I tried Armbian_5.44_S9xxx_Ubuntu_bionic_3.14.29_icewm_20180729.img.xz and it boots fine. Now, back to my original question: how do I convert the dtb?

I tried but still doesn't boot. At least I can still boot libreelec. I'm going to try with an older image.

I can only reply to question 4 and based on my limited sample of one: I bought their power supply with mi orange pi pc and it's been working 24/7 for the last year and half. Crossing fingers....

But the box is already booting from external media (sd/usb). If I use aml_autoscript.zip will it still work as it is working now? (i.e. no external media present boot from nand otherwise boot from external media)? I don't want to lose the ability to boot coreelec/libreelec.

I'll try one of the older images tomorrow, but I'd also like to boot a newer kernel (though it won't support hw acceleration) hence my original question on how to convert the 3.14 dtb.

I tried now by burning the image on an usb stick and modifying both uEnv.ini and extlinux/extlinux.conf (though I didn't touch uboot on the box so the former should be enough). I used both dtb_name=/dtb/meson-gxl-s905d-p230.dtb and dtb_name=/dtb/meson-gxl-s905d-p231.dtb but none of them worked (I just see the usb stick led flash for a short while then nothing, the screen stays on the "mecool" logo). I didn't boot into android to flash aml_update.zip, but the box was already booting from usb/sd (in fact I used the same stick to boot coreelec and an sd card to boot libreelec).

No, I didn't try any armbian image yet, I just searched the messages regarding the k1 pro and saw that there is (was?) no suitable dtb.

I'd like to try armbian on a mecool KI pro, any hint on how to convert the dtb from libreelec (kernel 3.14.29)?

Right, add a "count=x/512" or "bs=1 count=x" to the second dd command.

dd if=img of=/dev/mmcblk0 dd if=/dev/mmcblk0 of=img.1 cmp img img.1 Done, no need for this newfangled etcher thing
