Amlogic S905W2 64bit Cortex A35

[alexgolyd]

Hello. Please tell me how to set armbian to X98 Plus CPU "Amlogic S905W2 64bit Cortex A35" 

Tried to put S905W but it doesn't work anyway.

The s905w2 is a new cpu from amlogic.  As far as I know no one has tried to get mainline linux running on tv boxes containing that cpu  Generally when a manufacturer comes out with a new cpu it takes the main line linux community a couple of years to get a stable system working on it (if there is enough community support).  So I would suggest you use your box as an android box and come back in a year or so to see if there has been any movement to support this cpu. Or if you have the skills work on bringing support for the cpu into mainline linux.

Maybe this will help you?

@luxix  That link is for the s905w cpu which is a different cpu than the s905w2

Hi,

There is a dtb in coreelec https://coreelec.org/dtb/

[Jumperbillijumper]

Thanks @Igranie. I got the DTB! But now I neet a u-boot.ext file 😕

[Devmfc]

Hi,

 

You don't need a u-boot.ext to boot.  You can perfectly boot a  mainline kernel with a stock vendor u-boot.

 

The DTB you found for coreelec is a dtb for the vendor 5.4 kernel. That DTB is not compatible with mainline kernels.

 

There is some mainline kernel work being done for the Meson S4 (S905W2 is a Meson S4) at the moment. 

 

On my Github page I have a Debian and Ubuntu image containing a mainline compatible DTB for the S905W2. Everything works to create a headless Linux server. But there is no HDMI or sound yet unfortunately.

Thanks for your answer @Devmfc. Where can I find your Github to try that?

Where to get a stock vendor u-boot?

I have tv-box T95w2

[Energokom]

@Devmfc I'm using your image for S905w2, on the T95W2 TV box, help me start Wi-FI.

I have dts from the android firmware of my T95w2 TV box. There is also a dts from linux (meson-s4) on which I have a TV box running, but no Wi-FI

Can you tell me how to make changes to dts correctly in order to register the necessary SDIO bus?

 

I will install the SP6330 drivers myself

android-T95w2-2g.dts.7z meson-s4-s905w2-ap201.dts.7z

 

P.S. Thank you for your work

Hi,

 

You are posting on the Armbian forum.

The images you refer to are not Armbian images.

The people of Armbian don't like their forum be polluted with non-Armbian support request. I think that is quite understandable, don't you?

 

That being said, this answer is also true for Armbian tvbox, so maybe the answer is allowed: 

 

All those tvboxes are different, even if they look the same or even have the same 'model name' from the outside.

Especially the wifi modules are a lottery. So you have to be lucky to get a standard supported wifi module. And otherwise you'll have to learn a lot, google a lot to get wifi working. That's the 'fun' of tinkering with those cheap boxes. If you want a working wifi and don't want to learn all that... you are better of buying a well supported SBC instead.

 

Some pointers that might be helpful:

• decompile the dtb and look if the aml_wifi gpio's for power are the same gpios as in the DTB you use for mainline linux (sdio-pwrseq node) 
• sometimes it can help to lower the max-frequency property for the sdio node
• run

  ( vendev=( $( cat /sys/bus/mmc/devices/mmc2:*/{vendor,device} ) ) && echo "wifi SDIO ID: ${vendev[0]}:${vendev[1]}" )

   to get the driver vendor ID and device ID. If that doesn't work, previous two points are probably not ok. (Or wifi is not on SDIO bus, but is not very likely)
• (alternatively) open the box, look for the wifi markings and search google for the linux driver source and compile that driver

Have fun!

I have sp6330

 

On github, you said:

 

devmfc 5 days ago

I would expect the sp6330 to work... You could try to install the full firmware package via apt-get install firmware-linux. If that doesn't work you could try to see if dmesg complains about something... 

 

I looked, there is no mention of wi-fi in dmesg.

 

In the last message, I sent the original dts from android, can you take a look at it?

Hi,

Will there be a dtb version for s905w2 4/32? (Tanix w2 4/32). Version 2/16 works well. Thanks

[giga]

Did anyone get the WifI running on the H96Max (s905W2)?

the emmc memory is also not visible, it does'nt matter, which dtb file is deployed

@Devmfc Did you manage to run an Armbian system for the S905W2 processor with a graphical interface?

I have a TV Box S905W2 with SV6256P and I would like to convert it to Armbian.

[fefpi]

Is there any update or ongoing effort on the support for this SoC?
