Tool/software: TI C/C++ Compiler
Hello，
I need to solve this issue which I have got at the moment on J6. It was successful that I boot linux kernel from SD card and it can mount root file system .
The issue I am facing is that unabashed to mount the root file system when the boot mode was emmc boot mode. And this work refer to this http://processors.wiki.ti.com/index.php/Processor_SDK_Linux_Automotive_Software_Developers_Guide#Using_eMMC_Boot .
I see this fragment in the log:

But,if the SD card is plugged in the board ,the board can boot linux kernel from emmc and mount root file system.
