Have loaded GUI and drivers , on 4 different machines - both win 32 and win 64 . Removed all other USB devices . But this is the starting point . when I connect the H in standard mode instead of the correct USB sound I get the " warble" and notification that USB unknown ie it is not seeing it as a serial port and hence the GUI has no comms method and therefore can not load the firmware using the GUI.
I then put processor into dfu mode by raising Boot 0 pin (60) and using dfuse utility can communicate with it as a usb device .I try and load firmware for the FC at address 0x0800000 ie beginning of flash - this file is +- 601KB , which loads correctly but then when back in normal mode have the same symptoms - ie dead bird .
In the payload ( file ver 2.25 ) are 4 files ( the FC , a file called Flow ?? , The Gimbal , The Camera ) . Ideally a short description of what each does and the load address would help a lot. This type of info is not compromising their IP but facilitates a reload.
Does anyone have an email address of a yuneec technical person that I could ask this question .
