Can(or would) this tool support downloading uboot in the loader mode? #22

In my Firefly rk3288 development board, it's hard to get into the maskrom mode. So when I execute the command as rkdeveloptool db uboot.bin, I would get the error like "the device doesn't support this operation.". I read the source code and find that it can only execute function download_boot() and upgrade_loader() successfully in maskrom mode，but the upgrade_tool or other tools don't have the problem.

  1. I want to that could this tool support in loader mode (booting with pressed recovery key) to download the uboot.bin?
  2. What's the difference in these two modes, loader mode, and maskrom mode? It looks like the download happening after or before loading u-boot.
