Problems with WiFi driver QCA9377 on S912 PCB (TV Box H96 Pro+)

Since I bought my TV Box Android H96 Pro Plus 3/32GB green PCB with WiFi chipset QCA9377 has malfunctioned, the TV Box froze when I used WiFi, but it always worked fine when I use an ethernet cable. With CoreELEC, the same thing happened.

Yesterday I replaced the QCA9377 android drivers with updated drivers from https://github.com/boundarydevices/qca-firmware and packed the firmware again. Now android works well with ethernet cable and with WiFi.

I have searched for the QCA9377 drivers to replace them in CoreELEC firmware but I have not found it.

I have two questions:

1.- Does CoreELEC use the QCA9377 drivers of the android firmware that is installed in eMMC/NAND?

2.- If the answer to the previous question is NO, how can I replace the QCA9377 drivers in CoreELEC?

Thanks for your answer

What dtb you where using for CE?
I also have a H96Pro+ (green PCB, 2/16G) but I use only wired LAN.

  1. no

  2. you have to compile CE again. CE is using the https://github.com/boundarydevices/qca-firmware at: https://github.com/CoreELEC/qca-firmware. But CE is 2 commits ahead of the originalā€¦?

The 2 commits include a firmware update from the android image: ā€œVORKE Z6 Plus 20180606.imgā€

Checkout CE and modify this package:
https://github.com/CoreELEC/CoreELEC/blob/ee20dc33285298229e9ed49720167952a718d347/packages/linux-firmware/amlogic/qca9377-firmware-aml/package.mk to use 5e4b71211ecbb79e7693d2ee07361847f5a0cb40 insteed of d1c340302f986b06c8164b3064f1fb5722b90c6b. Then the firmware should be the same state as the boundarydevices repo.

The firmware should ge flashed when you upgrade your CE system with a new .tar file.

Thanks for your answer

gxm_q201_3g_1gbit.dtb did not work for my H96 Pro+, I use gxm_q200_k3_pro.dtb

My knowledge of Linux programming is zero and I do not have compilation tools, but thank you very much for your answer, I will try to solve it with tar updates.

I hope and request that in future CoreELEC updates the QCA9377 drivers be updated.

You have green PCB v2.2? gxm_q201_3g_1gbit.dtb is the right one!

I will compile a new 8.99.2 with the ā€œoldā€ firmware.

I have opened my H96 Pro+, the PCB is green and there is a label that says: ā€œCZ 3G+32G+9377 JOB 20170401ā€. I do not know anything else.

Can you post pictures of the PCB? Any more labels on it? I will upload a CE tar image later.

Is it this board:

The RAM of my H96 Pro+ is 2x ā€˜PPE09 093TPā€™, that is, it seems to be DDR4.

It is the same as 8.99.2 except the qca9377 driver.

Thank you, I will try what you tell me.

The new QCA9377 drivers for android finally also freeze my TV Box randomly in 5GHz WiFi.

Now Iā€™m testing WiFi 2.4GHz but the features are very bad (WiFi link speed 72Mbps) and speed tests too (average download speed of 15Mbps).

I have also observed that with QCA9377 there is an audio delay in relation to the video, of 250ms in Kodi for Android, although not in other applications.

I think that it is not necessary to modify CoreELEC, QCA9377 is a bad WiFi device, not recommended. TV Boxes that use QCA9377 should use ethernet cable.

I also using LAN, not WiFi!

I have discovered the reason for this behavior in WiFi 5 GHz. With some 5 GHz WiFi channels it seems that a resonance occurs that affects the hardware electronics and the processor stops. To solve this, simply change the WiFi transmission channel until you find one that works well.

FIXED!

Hello

I have the same PCB on my box.
I would like to try using Coreelec, but i donā€™t have enough knowledge in linux and compiling.
The link is no longer vailable, is there any possibility one of you post a new working link?

Thanks in advance
Cheers

You donā€™t need to compile anything. Adjust the WiFi channel like @cubimol has described above.
