Dear Michael Trimarchi,

Apart of the fact that is possible to add DFU to SPL, I am missing which is the real advantage. One goal of having split U-Boot into two images (SPL and U-Boot) is also to get a simpler and smaller image, letting the main U-Boot image doing the rest (hush shell, further drivers, and so on). We are now trying to push features that we currently have into SPL. Well, why cannot we simply run U-Boot if we need a DFU update ? Which are the real advantages for having DFU in SPL ?
USB flashing (no serial, no display) only otg
This does not answer Stefano's question: why do it in SPL, what's wrong with loading the real U-Boot for this purpose?
Because it's not possible, internal memory size of some cpus. You need to have a way to load the second stage and I'm discussing a general way to do.
Best regards,
Wolfgang Denk
What is your alternative way?
Michael
