I tend to dislike multiple notes blocks one after another. It is fine if you don't want to change this as it's a "personal preference". > .. j784s4_evm_rst_include_start_build_steps > > 1.

Just after: """ * tispl.bin_unsigned, u-boot.img_unsigned from :ref:`step 3.2 <j784s4_evm_rst_u_boot_a72>` """ In my opinion, it would make more sense than at the end of the Target Images section. > Image formats > ------------- > > -- > 2.34.1
