九联UNT402A S905L版本能USB启动，无法安装到emmc中

[jevian-ma]

确认板子是emmc，查了下KLM8G1GETF-B041 是三星半导体的 eMMC 5.1 嵌入式存储产品。但是U盘启动后运行lsblk，只能识别到sda，sda1，sda2。该怎么救？

[jevian-ma]

明明是emmc，就是无法识别，不知道是dtb问题还是android底包问题，如果是android底包，谁能提供一个可以用的底包啊。

降低dtb的频率至25hz试试，方法在仓库的帮助文档里

没效果，我按照documents/README.cn.md中反编译 dtb 文件的方法将meson-gxl-s905l2-x7-5g.dtb与meson-gxl-s905l3b-m302a.dtb的mmc@70000中max-frequency设置为0x17d7840，再生成新的dtb文件，然后替换了u盘中的文件，再次u盘启动设备，依旧无法工作。除了频率，还有其他影响因素吗？

修改mmc@74000的max-frequency为0x17d7840后成功识别了emmc，写入125号后，设备可以开机，也可以ping通，但是无法通过ssh连接上。请问您遇到过吗？

我焊接了ttl，发现卡在u-boot了，日志为

看来依旧是emmc频率问题，但是u盘中我已经修改了dtb的频率，可是还是不行啊。

[jevian-ma]

降低dtb的频率至25hz试试，方法在仓库的帮助文档里

我测试了几台设备，发现s905l不止hdmi正常输出，而且把emmc频率调整后，就能正常启动armbian。但是s905l3没有hdmi，而且烧录到emmc后无法启动。我用过“中兴B860AV3.1-M2_S905L3_安卓9.0_当贝桌面线刷固件包”与“android_tv_unt403a_s905l3b_and_unt402a_s905l3.tar.xz”两个android底包，效果一样，请问s905l与s905l3有啥区别？

[jevian-ma]

降低dtb的频率至25hz试试，方法在仓库的帮助文档里

问题解决了，更新了android底包，我用了 https://github.com/ophub/kernel/releases/tag/tools 下的android_tv_unt402a_s905l3.tar.gz无法启动，android_tv_unt403a_s905l3b_and_unt402a_s905l3.tar.xz也无法启动，后面测试了不少网上的android底包，终于发现 https://www.123pan.com/s/Jbe8Vv-x9JN.html 下的《盒子刷机固件大全分享》/《免费刷机固件大全分享》/A《当贝纯净桌面--固件大全》（固件更全）/4《九联盒子(UNT)固件合集》/735-九联UNT402A_S905L3_ATV_安卓9_线刷固件包（MI国际版原生启动界面）.zip后，再armbian-install选125才能开机。

我试了5~6个底包，不知道不同的底包区别是什么，为啥会影响有的无法工作，有的可以。

补充一下，我测试通过的”735-九联UNT402A_S905L3_ATV_安卓9_线刷固件包（MI国际版原生启动界面）.zip”底包与大神提供的”android_tv_unt402a_s905l3.tar.gz“UI很像，但是就是大神提供的就是不能启动，这块我反复验证了好几次。
