Device Information | 设备信息

• SOC: s905l3a （问了卖家）
• Model 魔百和 M401A

Armbian Version | 系统版本

• Kernel Version: 5.15.82
• Release: jammy

Describe the bug | 问题描述

下载和烧录以下镜像：
Armbian_23.02.0_amlogic_s905l3a_jammy_5.15.82_server_2022.12.09.img.gz
Armbian_23.02.0_amlogic_s905l3a_jammy_6.0.12_server_2022.12.09.img.gz
用adb connect IP
adb shell reboot update
然后插入优盘，屏幕提示无视频输入，然后一直卡在这里。
如果不插入优盘，会提示update失败和重启菜单。

请问有什么调试和判断方法？

[halida]

卖家说还需要改dtb和uEna，不知道怎么改。

[halida]

改了uEnv.txt：

FDT=/dtb/amlogic/meson-g12a-s905l3a-m401a.dtb

但是还是不行，设备黑屏，读了一下U盘，就没有反应了。

#732

看这个

[halida]

换

#732

看这个

现在是优盘都没有启动起来，插了键盘，numlock也没有反应。要换dtb文件？

[halida]

根据这里的教程：
https://bbs.hassbian.com/thread-17263-1-1.html

用了这个 meson-g12a-u200.dtb 启动起来了。
6.0不行，换5.15可以。

好的，那就有u200吧，这些盒子，同名不同芯的很多，不同省份的魔百和也有不一样的，只看名称可能不准确。XCray在这个问答区里也有很多关于M401A的经验分享，你可以多看看往期的帖子。

armbian-install失败了，提示：

看看磁盘：

看armbian-install，改成304的方法，提示：

M401A的那个你不能用，可能是频率高，最高的那个1800之前也有人不能使用，删除这个测试下。

https://github.com/unifreq/linux-5.15.y/blob/main/arch/arm64/boot/dts/amlogic/meson-g12a-s905l3a-m401a.dts#L146-L151

你无法正常使用emmc的问题调频后应该可以解决。

[halida]

删除这个是不是还需要重新编译啊？

[HoYin90]

根据这里的教程： https://bbs.hassbian.com/thread-17263-1-1.html

用了这个 meson-g12a-u200.dtb 启动起来了。 6.0不行，换5.15可以。 Armbian_23.02.0_amlogic_s905l3a_jammy_5.15.82_server_2022.12.09.img.gz

6.0的我也是黑屏

[halida]

@HoYin90 请问你跑起来了吗？烧录成功了不？我现在还是只能u盘跑。
