Hi @HansKim72, it is me again: I was just checking with Janani and it seems that you can place a valid config in the defconfig folder and that way you can use it as defconfig. In this case @saijanani.tx config ( config_bt ), once you place it on the defconfig, you can invoke it directly with make defconfig-config_bt and no need to mess around with .config.
Hi @HansKim72 , it seems that this is not working perfectly as there is some issues when running depmod on the board. We are currently looking into it. Sorry for the inconvenience…
