Try fdtget if wol = 0 or 1: fdtget /flash/dtb.img /ethernet@0xc9410000 wol
Does fw_printenv mac show your mac address?
What does dmesg | grep wol show?
Every command is working only for CoreELEC on SD card!
@Portisch
Thanks a lot for your support, now it is working.
I am not sure what was the problem, but if I created a completely new SD card with release version, update to your image and u-boot and follow your WOL guide. I got this message at suspend:
set mac for wol = 78:c2:c0:...
The ETH link keeps active in “standby” and “power down” mode and
sudo wakeonlan 78:C2:C0:....
starts the device.
I will now update step by step my eMMC installation.
Very good work, thanks again.
P.S.: How I can create just a kernel with my changes, e.g. add printk for debugging? I tried
PROJECT=Amlogic DEVICE=S912 ARCH=arm ./scripts/build linux
but the changed kernel is not recompiled. The “clean” script deletes the complete kernel source including my changes. I am also confused about “ARCH=arm” for a “aarch64” target.
Drop a xxx.patch file in /CoreELEC/packages/linux/patchs and recompile as normal. Then the linux-amlogic is getting purged and recompiled.
Sorry for bother you again, but I have still difficulties to bring up WOL with eMMC boot. Using the same Kernel/U-Boot and DTB I cannot see “set wol” at dmesg. Is eMMC boot using a different DTB?
Thanks a lot for any hint

@Portisch I just installed the working SD card to eMMC and WOL is working. Thanks a lot for your support
I’ve been using the new uboot for a while now. Sometimes while playing videos the box crashed. The screen just gets completely one random color. I thought that it might be due to the power supply again (because I use an external 2.5" HDD with USB on the box). It couldn’t play 4k content anymore because the box crashed after a few seconds.
Now I have flashed the original uboot and have to realize that there are no crash problems anymore.
That’s why I created a log via UART:

The Ram runs here with 816MHz (not 792MHz) and CL13 (not CL11). Does anyone have an idea what causes the crashes? If certain logs are needed, I can add them.
Do you have a “noname” H96Pro+? If yes I am thinking even 792MHz is too high. I am still getting problems while watching 1080i live TV.
So maybe try to reduce the RAM speed.
My system also freezes with that alternative u-boots. Tried them over months, but no success. Have an Alfawise H96 Pro+ 3G/32G.
At the moment i directly connected the box to my TVs USB port to power on, when TV is switched on
That might be your issue. The current provided by most TVs USB ports can be well below the stable 1A (or even 2A) that a lot of these boxes require to avoid issues, like you describe 
No, because with the original power supply it also freezes. I just use the TV USB now, to power on my device when TV is switched on. I also tried different power sources.
And with original u-boot no freezes with TV USB.
@TheChief79 My box never crashes. So maybe you want bring some log from the crash? But this will be a Kernel crash log and not a u-boot. So we can only searching by testing to find the reason. I guess you just should try the u-boot with a lower RAM speed.
I know, maybe there is something special with my box. I tried many versions with different speeds, no success. The normal uboot runs with 792Mhz and it also never crashes.
When S912 support will be dropped in the future, i will get another device with S905 chipset.
I compiled a new uboot yesterday. I tried 600Mhz to test it. And as it looks, everything seems to work without any problems! I will try higher speeds soon.
Now that Coreelec has fixed WOL, I’ve also tried this and it works!
However, I have the problem that I have a long time ago (H96 Pro+ S912 Standby mode):
- shut down the box via Coreelec
- press power button (or use WOL!)
- lights blue for a short time and then nothing happens
- only after pressing the power button again it starts (now WOL no longer works)
It stops exactly when it wants to register usb cfg. I do use a hdd from time to time (without additional power) and when I connect the hard disk, the power supply (2A) does not turn on the hdd(Box goes off when on). When the hard disk is running, everything works normally. But no matter if the hard disk is connected or not, the problem occurs.
I had the problem with the first functioning uboot. Then it disappeared after another flash from uboot. Now the problem exists again.
I also found out that starting with the remote control works with the original uboot! In the beginning I had a custom rom on it, but it didn’t work. (Now stock rom)
chips used for model ZH01-S912-TVBOX-V3.0:
On one side: 4x PE037-125 DG (Samtec or Spektec?)
other side: 4x Hynix H5TQ2G83CFR
I also just compiled for me test versions with 432, 504, 576, 648 and 720MHz 
I get still “stucking” picture “sometimes” with 792MHz. I will report which one will work without any picture problems.
@worldtest for your hdd/blue led problem: you have to make a uart uboot log. Only this will show the first steps of the resume. It should not matter if wakeup by IR remote, button, CEC or WOL.
It should show something like this on resume:
exit_reason:0x0b
set vddee to 0x03e8mv
set vdd_cpu a to 0x0460mv
set vdd_cpu a to 0x041amv

ddr resume time: 363us
cfg15 3b00000
cfg15 b3b00000

I fear this is one issue you won’t be able to solve as we have seen with other devices any memory labelled with S is generally Spectek which is a subsidiary of Micron and is everything they don’t want their name associated with. This memory is for price sensitive markets and generally has a 30% failure rate.
Dropping the DDR3 speeds provide a 10-15% downtick in performance. 32-bit wide memory channel is already starved for things like 4K and the reduction of memory bandwidth makes everything slower.
I reduced already the speed from 912 to 792MHz and it go much more stable. I did’t see any performance issue yet. I didn’t checked 4k media only 1080p/i and lower resolutions. So I will reduce the speed again by small steps to find a speed for the “noname” H96Pro+. As I heard the Alfawise H96Pro+ runs fine with 912MHz.
For sure - a price difference of ~€40 between “brand” and “noname” is showing some different parameters…
Here is the log: screenlog.0 (134.7 KB)
- Starts Coreelec with freshly plugged in power supply. (Blue light turns on)
- Coreelec shuts down
- Press the power button once: short blue light
- Press the power button a second time (Blue light turns on): Android starts (Log ends at half of the boot process)
Nothing is connected via USB.
Strangely the box starts when UART adapter is reading, Android and not Coreelec?! I mean, I hadn’t had that before.

Does that mean something?
With 600Mhz it takes quite a long time to change paths (external hard disk) in the file manager. In other words it always hangs up for a few seconds (annoys quite a bit). I can’t say to 100% whether it’s because of it. I haven’t noticed any other artefacts yet.
I have completely rebuilt Coreelec to avoid any related problems.
Edit: Strangely enough, the problem just disappeared?!
I have seen this stucking of the system also with a class 4 SD card. With a class 10 SD card the problem was gone.
I didn’t notice it was a slow class 4. I have now replaced it with a class 10 and everything runs smoothly, thanks!
