卡在这里了，电源重开也一样
写完EMMC之后，用U盘启动，也同样卡在这里

但是交换机对应端口灯是亮的，说明有些地方起到作用了。但是卡住了，进不去登录界面

你有没有先刷 https://github.com/ophub/kernel/releases/tag/tools
里对应m302a的安卓系统？

hoyzhang · 2023-02-03T14:07:19Z

我直接原版安卓启动，在TTL中reboot update的

hoyzhang · 2023-02-03T14:09:33Z

而且，HDMI也是一直不行的，想着等这个有线网络解决了，再看看怎么解决

ophub · 2023-02-03T14:13:33Z

列表中支持的盒子，一般都在kernel里面有一个对应的安卓系统，先刷这个安卓，再刷armbian。特别是一些魔百盒原来安卓系统版本低于9.0的是必须的。

对

hoyzhang · 2023-02-03T16:22:56Z

线刷了[android_tv_m302a_s905l3b.tar.xz]，之后adb中reboot update，同样是有线网卡无效。通过TTL再次执行
cd /boot

写入emmc时是用 armbian-install -m yes 么?

hoyzhang · 2023-02-04T05:12:59Z

写入emmc时是用 armbian-install -m yes 么?

是直接armbian-install，需要参数吗？

janko888 · 2023-02-04T05:29:04Z

是直接armbian-install，需要参数吗？

我的第一猜想是你U盘启动时有线网络是好的，说明安卓自身带的u-boot可以支持，如果你写入emmc时使用了写入mainline-uboot的方式,则可能导致网卡支持不了。

但你说armbian-install 是默认不带参数的话，应该是没有写入mainline-uboot的，所以我的猜想这里不正确。

我之前是安卓9固件+内核5.15.x+写入emmc不写入mainline-uboot的方式，网卡都正常。

hoyzhang · 2023-02-04T13:46:24Z

有办法找到其他原因吗？ U盘启动和EMMC启动有何不同呢？ uboot原因吗？

请教一下，在没有执行armbian-install前，从U盘启动的时候，最先执行哪个脚脚本？

ophub · 2023-02-04T14:35:53Z

启动分几个过程：先是BL1，这是cpu内置的，不依赖外部，然后是BL2，BL31，最后是BL33，BL33是编译出来的主线u-boot，其它几个都是安卓原厂的。

BL2主要完成内存初始化，也就是acs.bin这个要做的，从安卓系统里提取出来制作u-boot。

u-boot找脚本/boot/boot.src，加载zImage、uInitrd、dtb

整个过程可以从ttl里面看到u-boot的启动过程祥细的日志。

hoyzhang · 2023-02-05T15:59:24Z

dm1.txt是U盘启动的dmesg，dm2.txt是EMMC启动的dmesg，网卡仍然是不行，能看出问题吗？

[ 5.017645] meson8b-dwmac c9410000.ethernet: device MAC address 72:85:de:b7:d0:0c

不应该有这条日志，这条kmesg是 drivers/net/ethernet/stmicro/stmmac/stmmac_main.c L2874 的 stmmac_check_ether_addr 在检查不到有效MAC地址以后，随机生成MAC的报告。写入eMMC的u-boot执行的启动脚本可能没有正确传入MAC地址，而Aml的这个内置百兆MAC+PHY在地址不对的时候很可能出问题。

执行的启动脚本

具体是哪（几）个文件呢？能否修改一下，打印相关日志，重新启动看看？

这次还是4.4.2, 之前9.0的试了，卡在[BL31]: tee size: 0这个地方。

刷安卓9的系统，使用5.15的固件，添加u-boot。
这么做的可以。

hoyzhang · 2023-02-06T01:38:19Z

刷安卓9的系统，使用5.15的固件，添加u-boot。这么做的可以。
是上述的u-boot.ext和u-boot.emmc吗？

ophub · 2023-02-06T01:46:53Z

恩，可以一次都添加进去，实际使用时在usb用u-boot.ext，在emmc里用u-boot.emmc，两个都存在也无妨。

hoyzhang · 2023-02-06T02:08:02Z

恩，可以一次都添加进去，实际使用时在usb用u-boot.ext，在emmc里用u-boot.emmc，两个都存在也无妨。

9.0的一会我再试试。刚才EMMC启动卡在reading u-boot.emmc，我用U盘启动，把u-boot.emmc删除，再重新emmc启动，也仍然可以。

ophub · 2023-02-06T02:19:25Z

在5.15内核的固件里，这是可选项，一般盒子都不添加就可以正常使用，只有个别魔百和添加了有帮助。

hoyzhang · 2023-02-06T02:33:41Z

@ophub 9.0 固件需要擦除bootloader吗?

ophub · 2023-02-06T03:02:09Z

你的安卓系统里有，就选上。
如果选上写入失败，就取消。

hoyzhang · 2023-02-06T04:40:35Z

用了安卓9.0固件写入，勾选擦除bootloader，在TTL中reboot update。

[   11.544004] meson8b-dwmac c9410000.ethernet eth0: configuring for phy/rmii link mode

@ophub
仍然，EMMC启动情况下，eth0 没有running
和安卓4.4.2的固件不同的是， U盘启动情况下，eth0只有一个本地的ipv6地址，ipv4地址都没有。

emmc里添加u-boot了吗？
你用的哪个dtb

hoyzhang · 2023-02-06T04:52:30Z

一直用这个：meson-gxl-s905l3b-m302a.dtb
刚添加了u-boot，但是还是卡在

## Executing script at 01020000
reading u-boot.emmc
704408 bytes read in 22 ms (30.5 MiB/s)
## Starting application at 0x01000000 ...

U盘启动系统，进去删除u-boot.emmc，可以再次emmc启动

u-boot复制错了，用这个：u-boot-s905x-s912.bin

添加u-boot试试

cd /boot
cp -f u-boot-s905x-s912.bin u-boot.ext
cp -f u-boot-s905x-s912.bin u-boot.emmc
chmod +x u-boot.ext u-boot.emmc
sync && reboot

hoyzhang · 2023-02-06T05:37:02Z

原来说的添加u-boot是指这个，u-boot.ext一直有的，

加了u-boot.emmc依然无法启动，不加可以启动，网卡还是not running

hoyzhang · 2023-02-06T05:51:08Z

@ophub 有这个可能吗？

[ 5.017645] meson8b-dwmac c9410000.ethernet: device MAC address 72:85:de:b7:d0:0c

不应该有这条日志，这条kmesg是 drivers/net/ethernet/stmicro/stmmac/stmmac_main.c L2874 的 stmmac_check_ether_addr 在检查不到有效MAC地址以后，随机生成MAC的报告。写入eMMC的u-boot执行的启动脚本可能没有正确传入MAC地址，而Aml的这个内置百兆MAC+PHY在地址不对的时候很可能出问题。

ophub · 2023-02-06T06:00:06Z

几乎全部的盒子，在5.15下都不需要添加u-boot即可正常使用，只要能正常使用就不推荐添加。

但是据魔百和的几个用户反馈，他们添加了可以正常使用，不添加的有时网卡无法使用，需要拔插网线等操作。

比如 #989

这个M302A是janko888在 #615 分享的。你看看他的帖子。

hoyzhang · 2023-02-06T06:21:43Z

我在emmc上删除了u-boot.ext是可以启动的。
同一个型号，m302a，都是ys代工的，2+8，wifi芯片就有两种。uwe的emmc必须降频才能识别的到，太复杂了。现在主要是有线网卡，只能在u盘启动下才有用

如果安卓9固件+5.15+jammy还无法写入EMMC使用有线的话，不妨试一下安卓9固件+6.x+jammy的组合。我试过两种版本代工的302a，大概有70%还是能在6.x下写入emmc运行的,可能你的YS版本有惊喜呢。

谢谢，迟点试试。现在写入EMMC在RTL8822组件的盒子上，是可以的。

alegoho · 2023-02-06T13:50:37Z

你有没有先刷 https://github.com/ophub/kernel/releases/tag/tools 里对应m302a的安卓系统？

请问这里面的安卓系统是线刷吗？

ophub · 2023-02-06T13:53:53Z

对，用安卓线刷工具刷这个系统。

alegoho · 2023-02-06T14:05:34Z

USB BURNING TOOLS？

ophub · 2023-02-06T14:06:30Z

yes

alegoho · 2023-02-07T02:57:41Z

对，用安卓线刷工具刷这个系统。

请问UNT413A应该用那个固件？

hoyzhang · 2023-02-08T00:39:11Z

现在证实，我用了安卓4固件也是可以。要复制u-boot.emmc才能启动。同时，网线要拔掉，电源断掉一段时间后，再启动，才不会卡在 tee

M302A写入EMMC之后，有线网络无法使用，之前U盘启动是可以的 #1004
