Android 13 ATV AMLOGIC S912 (Lineage OS 20) LPDDR3

[ppromo47]

I repeat - qca Bluetooth does not work in los-20 and higher because Google made changes in the bt stack that are not compatible with the current libbt-vendor code. I do not yet know of any other way to connect to the HCI interface of the bt stack.

Ohh Apologies, I must have missed that before.

I guess then I have to live with LOS 19, please could you help me with :
- add VFD support (TX92)
- add ir-remote cfg (TX92)
- I can live without bluetooth remote aslong as bluetooth works and I can seldomly connect BLE devices.

- add VFD support (TX92)
- add ir-remote cfg (TX92)

not tested because no test device
download

Is this LPDDR 3/32 GB? last when I burned this ROM, the device was stuck on boot logo.

I'm currently working on modifying the existing ROM, but as soon as I add the changes, the device no longer boots. There seems to be no other option than to compile it completely from scratch

Ohh thank you for quick updates, also if I may suggest testing one patch at a time to narrow down on issues.

Would this ROM work with a Sunvell T95K Pro box? It also has the S912, Mali-T820 GPU, 2GB DDR3 RAM and AP6330 WiFi chip

This should work on any s912 boxes as along as it has lpddr3 ram
However still ensure to take a backup and don't try it if you don't know how to recover your device in case you brick it

I’m just worried that the WiFi won’t work

Either you try it and find out or bumerc can confirm....

You need a different build for ddr3 and Ampak wifi/bt. Ampak wifi+bt work fine in LineageOS. What makes you think wifi doesn't work?

Would it be possible to get this working on the Minix Neo U9-H? What would I need to do to get it to work? It has:
- S912 processor
- 16GB eMMC storage
- 2GB DDR3 RAM

I'm interested in revisiting this. Could anyone walk me through the steps I would need to take to get this working on the Minix Neo U9-H? I'm pretty new to this but would like to try. Where do I start? I tried building a different LineageOS once before and followed the build instructions but can't seem to find the instructions for this version

This rom is for the device with 3gb lpddr3 ram and 32gb storage, can you confirm specifications of your device?

[soldiaz]

Guess should work on 16GB units as well...

It has 2GB DDR3 RAM and 16GB eMMC. See also https://www.minix.us/products/NEO-U9-H.html for the full specifications.


Also, bumerc said

has a different wifi chipset, you have to compile it from scratch

Which is what I was referring to earlier. Which steps would I take for this? Or more importantly, where do I start?

Just a nudge to check on the progress, both the rom los19 and 20 are unusable without working bluetooth and ir remote. Forget the front display, possible to get just the ir remote working?

In case there is no fix then I think ATV 9 is the only option left.

I am going to give this a try,I have extracted the ROM using the Multi Image Kitchen, offcourse thank to the dev CryptoNick.
I also have a patch from brahner NonameV5_clock_uboot_Z6_PLUS.zip which basically does what bumerc mentioned, we need to copy the driver(openvfd.ko) to system/bin folder and then copy deamon service (OpenVFDService) to system/bin folder.

Now what I am missing is modification to dtb, below are the files i have from the kicthen, please can someone help the next step to unpack, modify and repack the dtb ?

Update 1 : I have figured how to extract DTB, found a DTB converter tool on github, renamed the file boot.PARTITION to boot.img which was extracted earlier using Multi Image Kitchen tool above, I copied the changed to DTB by comparing with tx92 rom provided by bumerc and boot.img is now ready.

Next step is to find out, how to create a flashable zip, to flash the driver, service and boot.img via recovery.....

Update 2 : I decided to port the changes from tx92 rom to h96pro, did following changes, extracted dts from boot.PARTITION and meason1,dtb
openvfd {
compatible = "open,vfd";
dev_name = "openvfd";
status = "okay";
openvfd_gpio_clk = <0x3c 0x4c 0x0>;
openvfd_gpio_dat = <0x3c 0x4b 0x0>;
openvfd_gpio_stb = <0x3c 0x35 0x0>;
openvfd_chars = [04 03 02 01 00];
openvfd_dot_bits = [00 01 03 02 04 05 06];
openvfd_display_type = <0x1 0x0 0x0 0x0>;
};

in the above code openvfd_display_type = was <0x1> earlier, I thought that was incorrect changed it to <0x1 0x0 0x0 0x0>;
Repacked the ROM and I was able to boot the ROM all fine, however still the front led doesnt wotk nor the IR remote.

bumerc : I can confirm the port was successfull however the service doesnt start, not sure why.




It also detects the service, but fails when I try the parameters.


with paratemters there is an error :


Please can you help?
