the question of emmc flash on sdk 7.0

Hi,

I doubt that you've built your u-boot with the wrong config file and therefore your environment is not set properly.

Can you try the following steps to see if there is any change:

Use the steps described here:    http://processors.wiki.ti.com/index.php/Sitara_Linux_Program_the_eMMC_on_Beaglebone_Black#Preparing_the_Images_to_be_Flashed

   cd ~/ti-sdk-am335x-evm-07.00.00.00/board-support/u-boot-2013.10-ti2013.12.01

   Any git magic you choose to do:

   git branch emmc

   git checkout emmc  

   Note that this adds configurations in your am335x_evm.h file in include/configs... check the differences.

2. Build U-Boot to create the U-Boot portion of the image to be flashed.

   Make sure your toolchain is properly exported:

   export PATH="~/ti-sdk-am335x-evm-07.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin":$PATH

   use these these additional steps before building u-boot image:

  export CROSS_COMPILE=arm-linux-gnueabihf-

  export ARCH=arm

  make am335x_evm_config

Continue with building the u-boot as described in the wiki:

   build U-Boot:

   make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- O=emmc am335x_boneblack

   Note:The O=emmc option will put the files created by this build in a emmc directory to keep them separate from the other files you might be using.  

Also note that you may skip ARCH=arm & CROSS_COMPILE=arm-linux-gneabihf- in the above make command.

Hope this helps.

Best Regards,

Yordan

Thank you Yordan!
I have tried all follow your steps,but it also failed,it has the same log.

I want to know how to set my boot_targets as emmc?

Hi Yordan,

      Thank you so much,i have finished that.

Hello, Could you elaborate about your final solution?

Thanks
