Actually, I think it's better to use SD card images where possible. - If you're using it just for experimentation, then the SD card is a much more flexible and less risky way to experiment. Personally, I even prefer kernel-linked-with-initramfs (and DTB) images, since that's just a single file and it automatically gives you the rest of the SD card as a FAT partition. - If you want to use it for an actual product (prototype), then you're anyway going to have to study in a bit more detail how the flash works and you'll probably want to do a slightly more complicated flash partitioning. That said, I do think it's really useful to have those tcl scripts for using SAM-BA. And of course, since I never use the defconfigs myself, my opinion is probably not that important.
