Hi Yuri

Thanks for reply.

I have yocto build ready.

I want to prepare .sdcard image that include u-boot, uImage, dtb , rootfs, bmp logo and additional script.

I want to include bmp logo and additional script in yocto build, so whenever I build Yocto build I get final image.

So I need to modify sdcard image generation  to include additional files.

Thanks

Saurabh

Hi Saurabh,

To add custom scripts and files, create a new meta layer of your own or create a new recipe on existing meta-*/recipr-*/ directory (refer other recipe to get reference), add your files and also add a bb file for the same. Now specify the name of bb file on the image which you are building. Better to create a new layer, refer section 5.1.8 in the link below to know how layers are created.

Yocto Project Development Manual​

Also add the name of your bb file in the image file (eg: images/core-image-minimal.bb etc)

You may mount the image file using "-o loop" option and treat  it as

file system.

Yuri.
