Basically I have to modify cpu-freq.c and recompile the kernel then. Would you mind releasing your build?

ps. Your post got cut off

I could release yes. But I think it is better in an extra thread for G02ref.

I've got implemented a working nand layout for this box now.

But I've have strange conflicts with SPI NOR using BOOT_12 pin and shared use of this pin with nand.

wetek play box do not use this. I think to get rid of this. But G02ref kernel freezes without SPI NOR. I do not know why.

I want to fix this. because I can see it in the log. It has no influence to kodi. kodi works well.

also I'm playing around to get the Availink AVL6211+AV2011 DVB-S/S2 to work...

done...

I've found that box is not a G18REF.

Model ist Videostrong (vsip-166) or prima

It is the aml-8726M6 SoC (G02REF) board with DVB-S2 tuner (not working yet)

working kernel changes:

a) it needs his own *.dtd device-tree src

b) also a diffrent cpu voltage table (lower)

c) an other nand and bootloader layout or like me no layout (sd boot).

d) scaling_governor=interactive is a main killer for the SoC

e) new .config

So I've tryed using my kernel and:

CONFIG_CMDLINE="root=/dev/ram0 rdinit=/init console=ttyS0,115200n8 consoleblank=0 scaling_governor=conservative scaling_min_freq=200000 scaling_max_freq=1512000 systemd.show_status=auto"

echo "*** LibreElec(g02ref) linux 3.10.X boot script ***"
echo

usb reset
if fatexist usb 0:1 KERNEL
then
echo "booting LibreElec from usb..."
fatload usb 0 82000000 KERNEL
setenv bootargs "boot=/dev/sda1 disk=LABEL=LIBREELEC_DISK BOOT_IMAGE=KERNEL debug degugging nohlt vmalloc=256m mem=1024m logo=osd1,0x84100000,720p"
bootm
exit
else
echo "No LibreElec KERNEL found on usb, scanning sdcard...!"
fi

if fatexist mmc 0:1 KERNEL
then
echo "booting LibreElec from sdcard..."
fatload mmc 0 82000000 KERNEL
setenv bootargs "boot=/dev/mmcblk0p1 disk=LABEL=LIBREELEC_DISK BOOT_IMAGE=KERNEL debug degugging nohlt vmalloc=256m mem=1024m logo=osd1,0x84100000,720p"
bootm
exit
else
echo "No LibreElec KERNEL Image found on sdcard, exit"
fi

exit

sd 2GB p1=FAT (aml_autoscript, KERNEL, SYSTEM) p2=ext3 LABEL=LIBREELEC_DISK

And it worked for half an hour with out a crash. Even the red lamp went on stopping the box.

I've got some audio issues on one mediathek stream, but other worked well.

And remotecontrol "OK" do not work in "not mouse mode" (total different key-layout/ir-protokoll like MX2)

it is not fast build, but works.

@yuanqi tested that at the begin

can now start, but kodi freezes after 1 min

I'm a step further now, deleting the nand table in kernel's device tree src, like the wetek play kernel patch do.

Now I think am very close to start LibreElec's Sysroot. (written to sd part2).

Please have a lock at the photo to fix my bootargs, to start SYSTEM

thank's a lot ...

@KOPRajs

nice work!

I've also got an old g18 very close to the Wetec Play (dvb-S2 similar avl chip).

Years ago I was used to boot xbmc from sdcard. But this was befor the 3.10 Kernel.

I've tested now 3 variants of configs with out any success. I could see in terminal (tty0) kernel is booting.

setup: sdcard p1=FAT with aml_autoscript (3 variants) to start from sdcard, KERNEL (file) p2=squashfs (dd from SYSTEM) (also a try with ext3) p3=LABEL=LIBREELEC_DISK ext3

src:

echo "*** openELEC(g18ref) linux 3.10.X boot script ***"
echo
if fatexist mmc 0:1 KERNEL
then
    echo "booting openELEC from sdcard..."
    fatload mmc 0 82000000 KERNEL
    setenv bootargs "root=/dev/ram0 rdinit=/init boot=/dev/mmcblk0p2 debug"
    bootm
    exit 
fi

I've also tryed to start SYSTEM as a file from FAT.

then I've build the whole 9.0 LibreElec for MX2 (gcc8: build kernel errors on asm)

I've fixed it by using src from that patch:

Patch "ARM: fix put_user() for gcc-8" has been added to the 4.4-stable tree - Patchwork

flashed all to sd booted same result:

kernel starts but i think it do not run the SYSTEM partition.

I've also built a lot's of 3.10 kernels, but they also didn't start partitions.

Could it be the bootloader? Maybe you could help me with a tipp?
