(S905x) LED display failed, ghost module #192

chris4git · 2022-03-22T08:47:09Z

Hi,
Armbian_22.05.0_Aml_s905x_focal_5.15.30_2022.03.20.1245.img on a T95 S905x TV box.
I try to activate the led display with armbian-led (and by hand) but it fails with all confs I've tried :

lsmod shows the openvfd module but
there is no traces in kernel log/dmesg
no /dev/openvfd
and no /sys/class/leds/openvfd

Any advice to debug that ?

Chris

Add your T95 conf

lx7741 · 2022-03-22T11:12:22Z

这个是要找到正确的配置才会有/sys/class/leds/openvfd文件吗？我执行都是找不到这个文件，open device failed

ophub · 2022-03-22T11:42:42Z

在那两个网站里找一下自己的配置

chris4git · 2022-03-22T16:20:35Z

https://github.com/ophub/amlogic-s9xxx-armbian/blob/main/build-armbian/armbian-docs/led_screen_display_control.md

Add your T95 conf

I only know my box use a fd628 controller and found that in /d/gpio of Android :
GPIOs 145-154, platform/c1109880.pinmux, ao-bank:
gpio-147 (gpio_key ) in hi
gpio-148 (fd628_dev ) out hi
gpio-149 (fd628_dev ) in hi
gpio-150 (fd628_dev ) out hi

The box specs are at http://specdevice.com/showspec.php?id=76fa-8e07-0033-c5870033c587

I tried several confs with armbian-led, including t95m_905x.conf but none produced entries in kernel log or /dev/openvfd entry. But the module is listed in lsmod...

ophub · 2022-03-22T23:59:01Z

rename t95m_905.conf to diy.conf
armbian-led 99

执行完出现这些错误，是DTB问题？我使用的是meson-g12a-x96-air.dtb ，是不是这个dtb无法启动openvfd功能呢？
还是说我配置有问题? 我从别人的96 air系统中抓到的进程参数是这样的

48行是点亮某些功能，可能你的没有这个功能，可以忽视。led正常点亮了没有？

lx7741 · 2022-03-23T01:58:57Z

正常点亮了没有

别人的X96 air系统是正常点亮的。（别人系统跟armbian有点像）

我的执行armbian-led 就显示上面那些错误。
我的diy配置跟x96 max一样的配置，是用64 63 的配置。

ophub · 2022-03-23T02:01:23Z

你是第一个air，你改一下diy.conf里面functions的值，可以为空。你知道原来安卓系统能显示什么，可以填，不知道就为空。

lx7741 · 2022-03-23T02:03:19Z

conf

我现在设置空，但是还是提示 open device failed no such file or directory 。
led灯没有亮，没有任何反应

那两个网站里有没air适合你的

是的，但是我这边有个别人刷的盒子，参数是65 和64，所以应该是一样的，他那个就正常亮。
是否是dtb要修改？
我看f大的dts文件内核上加了这个代码。
openvfd {
compatible = "open,vfd";
dev_name = "openvfd";
status = "okay";
};

ophub · 2022-03-23T02:17:29Z

你的不是最新的内核？
将系统的内核升级到 5.4.185、5.10.106、5.15.29、5.16.15 或更高版本。Armbian 系统使用 armbian-update 命令升级。

lx7741 · 2022-03-23T02:18:09Z

你的不是最新的内核？ armbian-update 升级到最新内核

我用的是最新的打包，5.4.186内核。

ophub · 2022-03-23T02:20:03Z

那就己经是包含了。那就调整diy.conf吧

lx7741 · 2022-03-23T02:57:01Z

那就己经是包含了。那就调整diy.conf吧

我x96 dts 加了这个代码以后就正常了。
openvfd {
compatible = "open,vfd";
dev_name = "openvfd";
status = "okay";
};

使用11的配置就可以启动

ophub · 2022-03-23T03:03:03Z

我是转存的f大的内核，现在的两个都是己经添加了这个功能的。你不放心的话可以去他网盘下载他保存的换一下，你看看有区别没。

lx7741 · 2022-03-23T03:05:26Z

我是转存的f大的内核，现在的两个都是己经添加了这个功能的

内核是有这个功能，但是需要配置dtb去启动？
我看你提供的配置表，f大都有修改dts文件，所以我怀疑是dts问题。
手动改了dts，重新编译dtb，替换，就正常了

ophub · 2022-03-23T03:13:43Z

https://github.com/ophub/kernel/tree/main/pub/stable/5.4.186

dts是dtb的源码。dtb是内核的文件之一。他在内核源码里添加了，那以后编译的就有了。
我是从他分享的地方下载转存的，同一个文件，你如果有怀疑不同，可以去下他网盘的替换。

lx7741 · 2022-03-23T03:16:11Z

不是你转存出错，是f大的X96 Air 的dts文件没有添加

openvfd {
compatible = "open,vfd";
dev_name = "openvfd";
status = "okay";
};
这个配置。
我手动修改meson-g12a-x96-air.dts，重新编译出一个dtb替换的
@ophub

ophub · 2022-03-23T03:19:13Z

我问一下他，如果漏了加一下，你测试可以使用的conf文件分享一下。设备的soc和dtb，内核版本等信息介绍一下，我加到列表里
你上面发的conf那个代码就是air测试完的正确配置？

lx7741 · 2022-03-23T03:21:58Z

X96 Air 2G 16G 100M Wifi dts和dtb文件：

Yes, I've done that, of course, with several confs, but :

@chris4git
Replace: meson-gxl-s905x-p212.dtb.zip

The dtb in the firmware does not add openvfd, downloaded the test I sent you, this is the 5.15 kernel, unzip it, and then upload and replace the file with the same name: /boot/dtb/amlogic/meson-gxl-s905x-p212. dtb

Can your T95 use meson-gxl-s905x-p212.dtb normally? Are you using uEnv.txt or extlinux.conf
Send your device information and firmware information.

There is no T95 support in the current installation and update scripts, and there is no modification to the /boot/extlinux/extlinux.conf file. Have you tried using /boot/uEnv.txt to start it?

But being able to use meson-gxl-s905x-p212.dtb is also good news. I can add T95 dedicated DTB according to this source code

Is it convenient for you to find a product link corresponding to your device?

Is it convenient to test the kernels of 5.4 and 5.10, can you start it with /boot/extlinux/extlinux.conf

Do you know how to modify this startup file? The UUID refers to the value in uEnv.txt, and the other content can be the content of /boot/extlinux/extlinux.conf in your current firmware.

If testing is available, I will add the device again later.
