Which recipe or what should I do to make changes to the image.json before the Yocto build?
Hi @SurriyaLuavan ,
The image.json is created by the image_type_tezi.bbclass, this file uses variables from other files to insert the data into the final image.json file.
As an example, the dtb parameters are created using this function where it searches for the variable
TORADEX_PRODUCT_IDS that is configured on machine configuration/include files, in case of iMX6ULL you can take a look into this file.
