Does anyone work on uwe5631-aml driver for CE-NO ?
I have uwe5621ds wifi/bt chip and I see that the uwe5631-aml is not included in CE-NO. I imported it from CE-NG and with some preliminary modifications to make it build under kernel 5.15 it successfully loaded. But it require more work to be functional.

Portisch · 24 November 2025 18:59

It never worked great and nobody did need it yet …

rozpruwacz · 25 November 2025 13:37

I managed to adapt uwe5631-aml for CE-NO and after simple tests it seems it works.

But there is some clash with EA6X21QX driver.
EA6X21QX driver installs this udev rule:

ENV{MODALIAS}=="?*", ENV{SUBSYSTEM}=="sdio", ENV{SDIO_ID}=="0000:0000", GOTO="load_module"
GOTO="end"

LABEL="load_module"
ENV{MODALIAS}=="?*", ENV{SUBSYSTEM}=="sdio", RUN{builtin}+="kmod load skw_sdio", RUN{builtin}+="kmod load skw"

LABEL="end"

which also triggers for the uwe5621ds wifi module … how can I distinguish those two devices in udev rules ?

Portisch · 26 November 2025 10:41

This was the old udev rule:

github.com/CoreELEC/CoreELEC

projects/Amlogic-ce/packages/linux-drivers/amlogic/uwe5631-aml/udev.d/80-unisoc_sdio.rules

coreelec-21

### UniSOC UWE5631 and UWE5621 kernel modules
ACTION=="add", ENV{SUBSYSTEM}=="sdio", ENV{OF_NAME}=="wifi", ENV{OF_COMPATIBLE_0}=="sprd,unisoc-wifi", \
  ATTRS{vendor}=="0x0000", ATTRS{device}=="0x0000", \
  RUN{builtin}+="kmod load sprdwl_ng sprdbt_tty hci_uart", \
  TAG+="systemd", ENV{SYSTEMD_WANTS}+="sprd_sdio-firmware-aml.service"

And you will need a special node in your DTS to enable the driver:

github.com/CoreELEC/common_drivers

arch/arm64/boot/dts/amlogic/sc2_s905x4_x96_x4_2g.dts

5.15.170_202508


      
          			groups = "GPIOH_4";
          			function = "gpio_periphs";
          			output-low;
          		}; 
          	};
          };
          
          &sd_emmc_a {
          	max-frequency = <150000000>;
          	brcmf: wifi@1 {
          		compatible = "sprd,unisoc-wifi";
          	};
          };
          
          &aml_bt {
          	bt_en-gpios = <&gpio    GPIOX_17 GPIO_ACTIVE_HIGH>;
          	hostwake-gpios = <&gpio GPIOX_19 GPIO_ACTIVE_HIGH>;
          };

What device is it for?

rozpruwacz · 26 November 2025 11:05

This will not solve the problem of unwanted skw module loading

Portisch · 26 November 2025 11:27

Sure, this must be adjusted as well like:

diff --git a/projects/Amlogic-ce/packages/linux-drivers/amlogic/EA6X21QX/udev.d/80-ea6x21qx.rules b/projects/Amlogic-ce/packages/linux-drivers/amlogic/EA6X21QX/udev.d/80-ea6x21qx.rules

But without even know what device you work on it’s hard to say how to solve this issue.

Please share your last changes to the driver as I just was able to find a device with such chip.
Then we are able to finish up the driver for CE-NO.

rozpruwacz · 26 November 2025 11:57

Ok, i will clean it up and make a pr, maybe even today

rozpruwacz · 26 November 2025 12:04

I use gtmedia gtcombo device

rozpruwacz · 26 November 2025 23:00

@Portisch I made a PR into this fork Port to linux 5.15 (part 2) by mczerski · Pull Request #1 · Stane1983/uwe5631-aml · GitHub, as @Stane1983 already started working on porting this driver into 5.15.

bazzle · 27 November 2025 01:24

S905x4

In NO I cannot get over 90 mb download using Speedtest app with wireless

In NG I can see up to 200+ mb using Speedtest app with wireless

I dont know if this helps. 2 clean installs

NO https://paste.coreelec.org/SaddledHometown

NG https://paste.coreelec/RoomieYvette

Portisch · 27 November 2025 06:51

Please ask there for help as this driver is used: GitHub - lwfinger/rtw88: A backport of the Realtek Wifi 5 drivers from the wireless-next repo.

Portisch · 27 November 2025 08:09

Thx, driver works. Wifi + BT is working on BuzzTV HD5. So the driver will be inlcuded with tomorrow nigthly.

You will still need to set the wifi node in your DT:

&sd_emmc_a {
	brcmf: wifi@1 {
		compatible = "sprd,unisoc-wifi";
	};
};

Nothing. Best is to emable tmate and we can more easy solve the issue:

hav · 27 November 2025 16:32

I left it just as it appears on the wiki, but I just activated the second line.

vpeter · 27 November 2025 16:42

Yes, now it is available. Leave it on and Portisch will look tomorrow.

hav · 27 November 2025 16:44

OK. Thanks.
