(S905x) LED display failed, ghost module

chris4git commented 2 years ago

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 commented 2 years ago

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 commented 2 years ago

在那两个网站里找一下自己的配置

chris4git commented 2 years ago

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...

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

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 commented 2 years ago

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 commented 2 years ago

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 commented 2 years ago

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 commented 2 years ago

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 commented 2 years ago

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 commented 2 years ago

那就己经是包含了。那就调整diy.conf吧

lx7741 commented 2 years ago

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 commented 2 years ago

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 commented 2 years ago

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 commented 2 years ago

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。

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 commented 2 years ago

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？

@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.

ls /boot
cat /boot/uEnv.txt

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.
