I can't talk for Naoki, but my use case is to test easily u-boot on my rockchip platforms without having to flash u-boot or to have some storage. > I would prefer to keep using one tool instead of two or more tools, > so I > don't think > > enable DFU in SPL is a good idea, using rockusb in SPL is better > here. To test u-boot, I'd like to use snagflash/snagboot as it's not rockchip specific. So, this means adding support for maskrom (which I've already written) and rockusb protocols to it. With DFU in SPL support in u- boot, this would mean nothing to do as the support for DFU is already in snagboot/snagflash. Arnaud
