Loading Yocto(3.10.17) To eMMC for iMX6SL based custom board

jansirani — Fri, 30 Sep 2016 08:46:31 GMT

Hai all,

we designed a custom board same as iMX6SLEVK board .it has both sdcard and eMMC boot selection and flashed images of Android4.4.2 to eMMC & sdcard successfully.

Then we tried Yocto(3.10.17) core-minimal-images and successfully flashed to the sdcard but unable to flash to eMMC.

Now inorder to flash yocto images to eMMC what are the changes we have to do in the kernel and uboot level.

Thanks and Regards,

D.jansirani

Hi Jansi

one can use Mfg Tools for eMMC programming

i.MX 6Family Manufacturing Toolkit for L3.10.17 (REV L3.10.17_1.0.0)
https://www.nxp.com/webapp/Download?colCode=IMX_6_MFG_L3.10.17_1.0.0_TOOL&appType=license&location=null&Parent_nodeId=1337695836026701499367&Parent_pageType=product

or erase partitions as suggested on

Thanks for the quick reply.

we are already using i.MX 6Family Manufacturing Toolkit for L3.10.17 (REV L3.10.17_1.0.0) to flash yocto images to the sdcard without any problem.

As the yocto default source code for iMX6SL compiles images for sdcard .

now we want to know what are the changes we have to do in kernel and uboot source code inorder to compile images (rootfs+uImage+uboot) to flash to eMMC Flash?

Note :

just to update i.MX 6Family Manufacturing Toolkit for L3.10.17 (REV L3.10.17_1.0.0) downloaded one will have the Mfgfirmware images for sdcard so we have to compile the uboot and uImage for the Mfg firmware also inorder to flash to eMMC.

as there is no script for i.MX6SL EVK for eMMC one can create
it using mfgtool2-mx6-sabresd-yocto-emmc.vbs as example.
