    Armbian for Amlogic S9xxx kernel 4.1x (>= ver 5.55)

    The answer is simple-a waste of time. Details can be found on the Internet on request, what is the difference between Android and Linux systems.

    Do you really see a big gap here ? Interesting figures are obtained. The NanoPi M4 @ 1.5Ghz-2Ghz Armbian Bionic 1h13m28s 1.4Ghz-1.8Ghz FriendlyElec Bionic 1h28m13s RockPi 4B @ 1.4Ghz-1.8Ghz Bionic 1h17m22s If I'm not mistaken : NanoPi M4 -> DDR3 RockPi 4B -> DDR4 The transition from 1.4 \ 1.8 to 1.5\2.0 for NanoPi M4 (DDR3), shows a significant difference , almost 15 minutes. So if you move the model from DDR4 to the same mode, we get about the same improvement. So the figure for RockPi 4B will be 1h17m - 15m = 1h2m It's only 11 minutes (That's less than 20%) worse than N2 (which has 4 super-fast cores). Yes, I know that you can try to raise the frequency of the N2, but it will require active cooling and vaunted stupid huge passive radiator will not allow this to be done without the addition of a fan. More interesting nuances. In the Blender test, has the following numbers. The temperature is almost 70 degrees, with an ambient temperature of only 22 degrees and a hidden semi-active cooling system from the air conditioner (i.e. these are very good conditions for the passive cooling system). This is just 50 minutes of running all the cores with maximum load (this is my assumption, because I do not know exactly whether I loaded Blender all cores work at 100% or not) and the standard frequency of 1.8\1.9 . And now look at the graphs from the official temperature test N2. There at an air temperature of 35 degrees, the temperature of N2 at a maximum load of 73 degrees. That is, only 3 degrees more than in the Blender test. Very amusing comparison. In this case, the Delta for the operation of the passive cooling system in the tests is obtained 70-22=48 and 73-35=38. That is, the difference between good conditions and complex 10 degrees (this is a significant value for passive cooling systems with such input parameters). I.e. imagine that you are easier to do after a hard work at 35 degrees than at 22. And if you look closely at the official chart, you can see the strange sawtooth behavior of the temperature. The oddity is that with a uniform maximum load and the onset of the thermal balance (the energy input is equal to the consumption) there is a significant temperature fluctuation for the passive cooling system. Possible reasons - either there is a cut-off when the temperature reaches critical, the system briefly and not noticeably for you, reduces the load, or the cooling system should instantly improve (for example, rapid heat removal by increasing the flow past the air radiator, which should take away the heat). In passive systems, there can be no sharp (instantaneous) fluctuations in air flows. For those who have brains, you can draw your own conclusions. IMHO s922 only enters the market and it is necessary time that this product "ripened" and began to be fully supported and work. rk3399 available for a long time and is well established. And it is important that the" old " rk3399 is not much inferior to the latest s922. I think Rockchip is not sitting still and working on new projects and maybe soon we can expect the appearance of improved versions of rk3399. Given that RK already has a good (and well-established) base in the form of rk3399, we can expect that we should expect very interesting events in the next few months.

    Armbian for TV box rk3328

    Write the details and attach the files (firmware and dts) to get Wi-Fi on the MX10. This will be useful for all users. For rk3328 has its own version of the media script and it works fine. I recommend you look at the last few pages of this topic, there are test details. This is a theme for the script.

    Armbian for Amlogic S9xxx kernel 4.1x (>= ver 5.55)

    Try test. Write to eMMC the standard firmware from which you took u-boot. And after that, check the standard option-activate multi-boot and try to run Armbian (with 4.20 kernel) as usual from external media. Running the kernel 3.14 is possible, but requires other scripts and settings at startup. To run Armbian in u-boot-2018, use the settings file /boot/extlinux/extlinux.conf

    I'm not accusing you of forgery. This was an example of how many different factors (both often implicit and difficult to track) affect events. Maybe I'm not looking hard enough, N2 is WoL ?

    Armbian for Amlogic S9xxx kernel 4.1x (>= ver 5.55)

    I uploaded a test image 5.76 NEXT with kernel 5 (for a quick check of u-boot) to the site. USB does not work in this image. Just downloaded two deb package with uboot (unzip them and use to write to the SD card files u-boot.bin). I checked another NEXT image from the 5.73 directory with the addition to the SD card after burning the image, u-boot.bin from DEB package for S905. The system starts normally and can be controlled via USB keyboard, but there is no wired network.

    @AndrewDB Now found one feature of. I recorded the last images for S905 to Sd card, changed in DTB settings (file /boot/extlinux/extlinux.conf) for VIM2 (S912) and checked the startup on S912 (without u-boot in eMMC). The system starts with the use of u-boot for VIM1 at S912. And in the console I saw this information. Ie checked all versions of DDR. Try the same version of the kernel startup 4\5 (image from S905 there is another u-boot). set vcck to 1120 mv set vddee to 1000 mv Board ID = 6 CPU clk: 1200MHz DQS-corr enabled DDR scramble enabled DDR3 chl: Rank0+1 @ 768MHz - FAIL DDR3 chl: Rank0 @ 768MHz - FAIL DDR3 chl: Rank0 16bit @ 768MHz - FAIL DDR4 chl: Rank0+1 @ 1008MHz - PASS Rank0: 2048MB(auto)-2T-18 Rank1: 1024MB(auto)-2T-18 DataBus test pass!

    Wait a bit, I am now building a new u-boot and it is advisable to test it on your model.

    Have you tried to write to eMMC the firmware from which you took this u-boot ? Perhaps with it the kernel 4 \ 5 will be able to be started.

    Can you show the full startup log of the new kernel (along with messages from u-boot) ?

    Quote: ------------------------ Whoa... careful there. Hot air rises, “heat” does not rise. As you yourself say, heat radiates. Heat leaves a hot object in straight lines as if it were light shining from the object. When it collides with something, that something gets the transferred energy (physicists in the audience please forgive me). A tiny amount will transfer to air, hence the inefficiency of using air as the transfer medium... but air is cheap, plentiful, non-electrically conductive, non-corrosive, and easy to move along the radiating surface. Thus a heat sink in any orientation will heat the things around it, and air in contact with hot surfaces will absorb some heat... becoming hot air and then expanding and rising (because it is less dense). So as long as that heated air can flow away, you will end up with a convective flow and a constant supply of cooler air (that gets heated and flows away, etc). Don’t put your heat sink in an upside down bowl, and you should be fine. ------------------------- Sorry, I could not resist, it's just a masterpiece of stupidity and ignorance of the basic laws of physics ... For reference. If the radiator "looks" at the surface of the table, the radiation is reflected from the surface of the table (all solids have a reflection) and returns back to the radiator (only a small part, where the radiator ends, will be reflected in the environment (i.e. will leave from N2). Only a very small part of the energy is transferred to the top of the table surface and tries to heat it. As soon as the top of the table is heated, it starts to heat the air above it and .... this heated air rises back to the radiator. The better the reflection of the table, the greater the back radiation. Used black radiator, so it is much better to get back the heat (in the form of radiation) than gives. For this reason , all heat exchangers, which are used to heat the water by the sun (radiation) are specially painted in black , which would be better to take energy (pay attention, do not give, namely to receive energy). Radiation works only from surfaces that "look" into the environment. That is, all the surfaces of the lamellas on the radiator emit energy into the environment only by a very small surface (on the tops of the lamellas). The rest of the surface looks at each other and radiates energy back to each other (i.e. does not do any good to remove heat from the system). Only a smooth plate reflects the entire surface. By the way, just a reflection from the radiator, which is directed towards the PSB Board, "helps" to heat the components on it. Deep lamel are designed to increase the area of air contact with the radiator, but they work only with good air movement past them (with active air supply). When natural air circulation Delta recoil does not exceed 10-20 W\g, and when forced to 200-250 W\g.

    1. Arguments that" it is possible to turn a radiator upwards " - aren't discussed. If desired, you can do anything. This solution was not offered by the developers of HK immediately during the development (and in the description of the use), so this use case is not the merit of the developers of HK, which is already confirmed by the facts described earlier. 2. A huge radiator is not a plus, but a minus for developers, because developers, instead of doing something good (correctly calculated design), decided the issue of cooling blunt and not effective increase in costs. With an unjustified increase in the weight of the entire structure, the hidden costs incurred by buyers are increased (the manufacturer always includes them in the final price). For example, transportation and postage costs for the delivery of final products to consumers, the cost of production is not the right radiator, etc.. 3. It's funny to read the opposite reasoning, in the beginning argue about the possibility of turning the radiator up (and by the way, only in this position the radiator will benefit from heat radiation), and then talk about the ease of connecting additional devices. It is interesting to see how the user will work with the display, which is connected face to the table. 4. Given the fact that all the numbers about the temperature, frequency, number of cores used their modes, etc., forms a closed binary code for "secret algorithms", I am skeptical about all the results, except one - the real work. All artificially invented tests are a measurement of a" spherical horse in a vacuum", which is not difficult to" teach " the correct answers. PS test Results under air conditioning - a good example of how you can (if desired) to organize any "correct" tests.

    With the correct DTB, the wired network works on all models.
