Thanks, Yishin. Not having had the time to read all the Yocto documentation, notably the BSP Developer's Guide, I don't know whether a BSP gets down to nitty-gritty details of the board and passes compiler flags etc to the toolchain accordingly or if it merely makes it easy to wrap all the software resources in one blanket. My FINO (First-in, Never-out) stack contains many reading assignments like this one :) Joking aside, I have accumulated some limited-resource ARM boards and appliances for which I'd like to create custom BSPs and for which there are no member-sponsors in the Yocto Project doing the work for me. It's a nonstarter to build anything complicated, certainly not a kernel, directly on these boards; the CPU power and RAM size are just too limiting even if NFS gives access to adequate storage. When I had just one device, OpenEmbedded/BitBake worked well enough but once I started playing with more devices I felt like a one-armed wallpaper-hanger as I tried to manage the proliferation of directories and builds. I like that the Yocto Project came into being to deal with exactly this kind of problem.
