Android build error on creating dtbo.img

[sid1]

I am trying to add drivers for a Wi-Fi/ BT Module into Android p9 and building the OS, but seem to hit an error where dtbo.img is unable to be created. I am unable to resolve this issue for a while

I am building this for NXP imx8m board which is running Android p9 and get the above error during the build
