(maybe because of phandle order?) i thing there is maybe a timming problem between wlan dis , sdio data and host wake up wlan . the power sequence driver supports the following two properties, see [0]: - post-power-on-delay-ms - power-off-delay-us Those are not set, meaning no delay is applied. For reference, these are the delays which are used on the Endless Mini (which also has a RTL8723BS module): [1] Do you know more about these delays (whether they are needed and how long they are supposed to be)? i read also the AP6330 and BCM4330 Datasheet for both of them is a start order inside the datashet ( i think that RTL8723BS should have same timming) . the time between 32k clock and WLAN_dis should be more than minimum 2 clock cycle (1/32kHZ * 2cycle = 0.06ms ) also that AP6330 has most identical pinout as RTL8723BS ( i did not get the pinout of BCM4330 because datasheet only has information to the chip and not the small extra pcb where the chip is mount) on Android 4.4 my box told me that GPIOAO_6 ist chip enable and GPIOX_11 ist wlan enable mybe a clue is that in the HArdkernel S805 Datasheet the GPIOAO_6 is also a 32k clock output (site 42 table 10 Func1 maybe (but i also found some Dts file from old S805 RTL8723bs box they use only GPIOX_11 and powerPin2 was comment out ) -> i have another question , do we use the same wifi.c file for the meson8m2 boxes as for endless mini ? i have taken a closer look at the file and the two delay information you are mention are not in the wifi. c is neither a function nor an instance, it just takes two fixed values "mdelay(200)" line 156 , furthermore we ignore the output level of wifi_power_gpio2 and automatically set it to "1" line 378 , so it is important which of the two pins is passed to the header file first (translate with DEEPL) <- it could be that GPIOAO_6 is the host wake up wlan ? is it possible to change the activation order for the gpio pins by change it in dts ? please check my previous mails. I think that GPIOX_21 is the wifi host wakeup pin because it is marked as "input" on the 3.10 kernel. you can change the order of the GPIOs inside the sdio_pwrseq node, but all GPIOs are managed together (meaning there's virtually no delay between enabling the first and the second one). I am not sure if using an MMC power sequence is the right thing to do, because the card is detected for me regardless of whether GPIOX_11 is HIGH or LOW. The RTL8723BS driver currently does not manage any GPIOs.

Realtek only sells the RTL8723BS chip on it's own. But it needs some extra components (crystals, resistors, capacitors, ...) When changing some of these components you need to certify (FCC / CE / some other regulatory) the wifi card again (to ensure it follows the specification and does not interfere with other devices). Thus there are manufacturers (for example FN-LINK) that sell certified RTL8723BS modules. Also one datasheet can describe the signal as "active low". However, if there is a small transistor circuit on the module PCB (or the main SoC PCB) then that can "flip" the signal, meaning: the SoC outputs HIGH but the module gets LOW - or vice versa. Thus we describe the GPIOs from the GPIO controller (in this case: Amlogic SoC) perspective.

I don't know why the vendor kernel requests this as GPIO because actually it is using the xtal_32k_out mux on the pin controller. I assume this is what you have for pin24 below (32k/RTC clock/WLAN clock), because it's output is 32.768kHz (or rounded: 32kHz) gpio-123 (sdio_wifi ) out hi this one is GPIOX_11 and called "gpio-402" in your 5.7 kernel GPIO dump gpio-132 (bt_rfkill ) out hi -> pin 34 Bt_dis (Bluetooth disable) this one is GPIOX_20 and not part of your 5.7 kernel GPIO dump Linux 5.8 will gain RTL8723BS Bluetooth support -> with that the GPIO will show up as well do you know if this is related to the wifi part somehow? gpio-133 (sdio_wifi ) in hi this one is GPIOX_21 and not part of your 5.7 kernel GPIO dump either. It is the "wifi host wake" and should not be related to your issue. the SDIO wifi card uses it to let the host know that data is available and the host should resume from suspend.

RTL8723BS driver doesn't work for,me but I can help testing
Hello Community I was referred to you by Martin. I have an older Android TV box that runs for over 3 years with Armbian Linux (Debian Jessie Headless Kernel 3.10.99). I'm looking forward to the new kernels and I'm glad that older hardware is still supported. Together with Oleg(balbes150) and Martin(xdarklight) I am testing the new kernel 5.x for ARM ( Amlogic S812 / Meson8m2 ) . Martin has written a patch for the SDIO controller in the last days so that also Wifi module and MMC are recognized. I could now successfully load the driver module RTLWIFI from the kernel. But unfortunately the card is only listed on the desktop as "not ready" or in the terminal (iwlist) as "no scan result". In the dmesg/lsmod RTLWIFI->RTL8723bs is loaded and the module is loaded with version v4.3.5.5_12290.20140916_BTCOEX20140507-4E40 . I would like to ask you to check the driver because even in kernel 3.10.99 a newer version (v4.3.16_13854.20150410_BTCOEX20150119-5844) is loaded and also at github are hard kernels ( version 2017 Kernel 4.9>) and ap17 and thirdyouth (v5.2.17.1_26955.20180307_COEX20180201-6f52). More recent ones can also be found - these have already been successfully tested with Debian 10. i hope that this may solve the problem with my Linux box. I would appreciate feedback on this request or information about debugging . My Linux box is also available for testing purposes Kindly Tobias Baumann (RaptorSDS) -- Diese E-Mail wurde von AVG auf Viren geprüft. http://www.avg.com ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
