i.MX8QXP boot Android9.0 , Kernel panic

yangbaojian — Mon, 22 Apr 2019 15:23:50 GMT

我使用的是imx8qxp板子，3G内存，32GEMMC；烧录Android9.0板子系统以后，内核启动崩溃，请帮忙分析下问题原因在哪里？

Hello yangbaojian,

Look like you need to reprogram again the SD, because the error it said is not fully programmed.

Regards

Hello Bio_TICFSL：

Thank you very much for receiving your reply. Can you elaborate on SD? Is this required to be configured in the kernel? Still something else?

You can download the demo image and program your SD.

在boot目录中找下imx8qxp_mek.c，按这个修改试试。
