How can we add our own recipes to meta-intel-fpga layer to build rootfs

[sgannava]

Hi,

I am following the below documentation to build custom linux image for Arria10 SoCDK. Initially, I  followed the steps mentioned in the documentation to get familiarize with the process and the image size turned out to be 82MB. After adding the custom recipes in rootfs-->meta-intel-fpga layer and custom dts whie building kernel image, I rebuilt the image, but the size of the image remains unchanged. I am not sure if I followed correct steps in adding recipes? Any help would be appreciable.

Thanks

Hi,

Please follow the below link for understanding and creating custom/own layer using the yocto.

Hi Tiwari,

Thanks for the response

I have added my files as recipes in meta-intel-fpga layer itself without creating a new layer. Now I do not need to add/edit any layer .conf file as well. Hope that is also fine

Thanks
