This is not exactly a "how does the yocto" support-thing. Yocto is not the OS. The OS by itself is the Linux kernel, which has extensive NAND support in a lot of varieties. If you want to have a look, see https://elixir.bootlin.com/linux/latest/source/drivers/mtd and especially the nand subdirectory. In a nutshell it goes like this: if you buy a board, ask whomever gave it to you for a kernel plus config that works. Also, they are in most cases also obliged to tell you how to write something to the (NAND-)flash. For the userspace side, there is the mtd-utils suite: http://www.linux-mtd.infradead.org which is already nicely packaged for OE: http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-devtools/mtd/mtd-utils_git.bb So these are your starting points, you have to apply them to your specific setup yourself. The only common things I can think of is: 1) make sure your kernel+config support the flash chip in use 2) install the mtd-utils for interacting with it.
