The problem is that for some reason the usb_dfu firmware doesn't work proper with all usb chipsets.
I tried once to debug it on one of my laptops with the same problem - something goes very wrong in dfu/usb algorithm.
I reported the problem on developers list, but there wasn't any help.
I found the only solution - trying other laptop (or using external usb controller on it, for example as ExpressCard).
Looks like guys there, who use F4 controllers, switching to the internal bootloader and dfu-util, which should work better.
If you send me a photo of your KroozSD's downside, I'll probably can tell you ho to switch to internal bootloader and use dfu-util.
When i try to upload the firmware to krooz board using bootloader i get this error:
sometime the upload process finish but the board not initialize.
Sometime the uoload finished but i get some crazy behaviour in flight.
for now i tried more than 20 times and the process cannot finish.
If i try in my very old laptop it work ok.
when i try in one of my 3 new laptops it fail.
any idea ?
