Peter Li：
Hi, Tian:
which SDK are you going to run?
Linux:
Vision SDK: www.ti.com/…/processor-sdk-tdax sdk&tisearch=Search-EN-Everything
Android:
xin tian：
回复 Peter Li:
vision_sdk ; I compile the kernel according to this document.《VisionSDK_Linux_UserGuide.pdf》
Peter Li：
回复 xin tian:
Hi, Tian:
Please check the boot configuration.
I would recommend to use SD card as the boot media at the project beginning. Prepare the SDcard according to the VisionSDK user guide.
In your log, it seems the board is booting from eMMC.
Thanks.

回复 Peter Li:
Hi，Li：
I have set the hardware pins as described.
How to boot from sd card?
Is there a problem with the uboot parameters?
Peter Li：
回复 xin tian:
the console log shown above, says it boots from eMMC (not SD).
xin tian：
回复 Peter Li:
Hi，Li：yes，I get it. but I don't know how to boot from SD card.Can you provide UBOOT configuration for SD card boot?
Peter Li：
回复 xin tian:
Hi, Tian:
If the sysboots are properly configured as described in the user guide, and the SD card used is a valid card (the user guide also tells how to format a SD card), the EVM will try to boot from SD card first.
There is nothing needed for UBOOT configuration.
