Hello.
That's for boards with NAND, eMMC users don't need that. What flash memory do you have?
I have emmc. I just want to make my ram faster for gaming with overclocked gpu ofc

Hello everyone.i'm the follower of armbian and using it's rk322x version about 1-2 years.i used to use kernel 4.4 so far and tried mainline kernel too.i need help about the above tvbox.MXQ_RK3229_EMCP_V3.1 .when i erase rom with android tool for windows i could be able to boot it from sdcard with mainline kernel.But i can't install armbian to emmc with armbian-config (install to emmc menu disappears or no exist).i used usb male to male cable too but no way.i found a topic at this link too.i asked there too.waiting there too.But i'm hopeful from here at first.https://www.clubedohardware.com.br/topic/1523441-como-dar-umbrick-na-tv-box-mxq-rk3229-v31/
Please help me about this subject.i'll be very glad to learn howto install it to emmc.ThanksWe have exactly the same board I just used the multitool burned on an sd card with the armbian image located on the images folder then I just plug in the sd card on the board then power it on. You can erase the flash from there then you can write the image that you placed on the images folder then reboot.

Hi! can I use the nand bootloader upgrade for emmc because I want to make my ram go 660mhz. If I follow the instructions it just errors Download Boot Fail and I don't know how to fix it. Please tell me how

Hello,
memory performance is a bit problematic. The frequency is fixed at boot time to 300 Mhz for DDR2 and 600 Mhz for DDR3 boxes. There are three main reasons:
- there is a constraint against an internal clock running at 1200 Mhz and RAM must be an integer divisor of that frequency (1200/300 = 4, 1200/400 = 3)
- the kernel memory controller driver, that does the memory reclocking up to 800 Mhz, needs the proprietary rockchip trust os to work, but since I use an open source trust os (OPTEE) here, it will never work
- DRAM chips among boards are different and may have different access timings, so something that works for a box may not work for another one, even if it is configured at the very same frequency. Sometimes the boards are so cheap the manufacturer installs faulty memory banks that are not even able to work at their rated frequency. To reduce the number of non-booting boards, I chose to take the conservative approach, which is also enforced by the limits of the point 1
Changing the dram frequency is not an easy task: you need the right ddrbin (the binary piece of code that initializes the DRAM), recompile u-boot, glue them together with the trust os to produce the idbloader and finally install it at sector 0x40 of the flash/sdcard.
This is all done automatically by armbian scripts, so you can read the code to make your way through.
BTW, I'm taking in consideration to experiment with the ARM trusted firmware (ATF) and maybe in the future activate the DMC kernel driver to allow reclocking.
Hi, I've tried to make a new ddrbin using the rockchip tools in their github but no luck it doesn't boot.

yes it is perfectly normal. It will resize itself after you boot into it. Have fun

Okay thanks is it possible to fix it?

These boxes are really nice. After 2 days of compiling 0ad (yes it took that long) I need to allocate more vram as I am getting segmentation fault. I have tried many different things but nothing worked. Is it possible to allocate more ram for the gpu? How?
-
I'm looking forward for that but can it go higher than 800 Mhz because my ram chip can go up to 933 Mhz

Hello, the RAM seems to have become the bottleneck now. No changes in the dtb makes no difference whatsoever. How do I make it so that I can control the ram?

I just changed clock-latency = <0x9c40> to clock-latency = <0xc350> and it made being able to clock to 1464Mhz possible and it is pretty stable. You can see the performance improvements below
Clock Speed 1464Mhz 1200Mhz
CPU Blowfish 9.71 11.80
CPU Fibonacci 2.78 3.40
CPU N-Queens 16.60 18.38
FPU FFT 11.65 13.83
FPU Ray Tracing 7.90 9.69lower is better
CPU Z-lib 0.09 0.08
CPU CryptoHash 100.98 81.32
higher is better
Clock Speed 750Mhz 400Mhz
glmark2 Score 57 57how do I remove the fps limit? glmark2 is limited to 60 fps while Quake 3 is limited to 15 even when staring at the floor or when shooting enemies.
Here's the dtb I used https://cdn.discordapp.com/attachments/699217226020028456/732893355738005564/rk322x-box.dtb

Thank you for enlightening me, I managed to overclock my rk3228a to 1.46Ghz stable and it only needed an adjustment to the clock latency. Now there is a massive improvement in performance 1.2Ghz to 1.46Ghz with the memory clocked to 2133mhz and the gpu to 700mhz and it is pretty stable. I can finally play quake 3 very smoothly. Thanks a lot

Is it possible to overclock these boxes? I've tried modifying the dtb but it seems that nothing works? It can go to ~1.4Ghz just fine but anything beyond that gets "ignored" I was hoping that I could go to 1.5Ghz but it seems that something is holding me back at 1.4Ghz it is not unstable or anything but if it would be possible to remove the "restriction" I would be really happy. I am using Armbian_20.08.0-trunk_Rk322x-box_focal_legacy_4.4.194_desktop

Hello! I have X88PRO-S905X3-D4-V1.0. I used meson-sm1-sei610.dtb and the ethernet does not work. I tried using the eth fix dtb and tried making a script that makes the auto negotiation off on startup and the ethernet still does not work. Please help

oh okay the board still boots I guess it is a durable board thank you I just reflash the original android image when it doesn't seem to boot
