You should be able to boot from the SD card, but it depends a bit on the device and the bootloaders. I am trying to get up to date VM images ready this weekend. I have just added it to the wishlist: https://leste.maemo.org/Wishlist What framework does dooble use? Looks like it's Qt5? I haven't heard of it before. Yes! I just back from a long work trip, but plan to spend a good chunk of the remainder of the month and next month on Leste. Expect an update post before the new year.
