ADD VIM3 TO ANDROID SOURCE CODE

Hi guys hope you are doing well all well i wanna test how to add a new device to aosp code source given here i did all the steps well but ithink that they fixed the path i have tried to change the envsetup.sh but i got the same problem no device added so please can you tell me which file did you guys change to fix the path /device/khadas

From what I know, what you need is a file called AndroidProduct.mk that’s located in the device/{odm}/{Product} and would contain
'PRODUCT_MAKEFILES :=
$(LOCAL_DIR)/{Product} ’
