Re: [Paparazzi-devel] error when uploading code to ppz

[Felix Ruess]

Hi guys,

does the krooz bootloader really report it self as Product: DFU Demo and Manufacturer: Black Sphere Technologies?

If yes, it would really make sense to change that in the krooz bootloader so it will reports its name properly and that can put in the whitelist of the dfu script so you don't have to use --any.

Or did you upload the software to another board by accident?

Cheers, Felix

Hi Eduardo!

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.

hello,
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.
