hi,

     我在用imx8qm evk 做开发,最近下载了安卓P系统到EMMC,并且在EMMC启动模式下,可以正常启动到anroid P界面。但是我发现在设置为SD卡启动的情况,板子无法引导系统启动,我使用NXP官网上的linux镜像文件重新做了SD卡,但是依旧无法启动,串口没没有任何输出信息!请问如何解决?

请问你烧写成功了吗?烧写过程log file里能看到烧写过程。 还有从SD 卡启动的话,你boot mode有没有设置正确,你查看一下。

EMMC正常启动,你上面烧写的是你自己移植的BSP编译的images还是Demo? Demo images是给我们官网开发板的,如果你的板子设计和开发板设计有不一样的地方,还是不能直接用的。

     my imx8qm mek works well using booting android P os from emmc. But it is not working, when switch to boot from SD card. In sd card I use L4.14.98_2.0.0_ga_images_MX8QMMEK img fsl-image-validation-imx-imx8qmmek.sdcard, wich is downlaod from NXP website. I don't why becasue  in this case, serial port output nothing.
