eMMC booting in custom imx6 sabresd board

[Subodh_K]

Hi all,

I am working on a project which is based on imx6 sabresd board . My SDK is yocto 1.6 with daisy branch and BSP is kernel 3.10.17 and u-boot is 2014 version . currently our boot media is SD card but in our end product we have to keep eMMC as booting media so for eMMC i have configured the platform data ,pinmuxing and all according to our custom board.

When i build a BSP using yocto bitbake command it's making as fsl-image-multimedia.sdcard which is flashed in SD card using dd command .

But to flash in eMMC either we have to use MFG tool or boot with SD card and then use dd command to write in eMMC.

So can anyone tell me the way to generate the image for Mfg tool using Yocto SDK?

Otherwise help me to set up the Mfg tool with the individual kernel and u-boot image which is built using

make uImage LOADADDR <address>  -- To build kernel

./MAKEALL <board name>                   --To build u-boot

Hi Subodh

Freescale_Yocto_Project_User's_Guide.pdf p.5 from L3.10.17_1.0.0_LINUX_DOCS

shows image recipe for building MFG tool

Hi igor,

I did what you said and also refered the yocto_project_user _Guide.pdf.

Using bitbake command bitbake fsl-image-manufacturing it gives me an error:

ERROR: Nothing PROVIDES 'fsl-image-manufacturing'

In User Guide it's given to compile kernel using default config file  imx_v7_mfg_defconfig

But not getting idea to get compiled u-boot for Mfg tool.

please guide me soon to get it compiled .

Best Regards,

Subodh

Hi

u-boot for emmc can be generate using machine specific file.

meta-fsl-arm\conf\machine\imx6qsabresd.conf

UBOOT_CONFIG ??= " "
