i have an older starling (v1) with a preinstalled 1.1.4 voxl2 sdk. i'm trying to flash it with the latest 1.4.5 version and i'm having problems as the device does not go into fastboot mode, note i've tried power cycling and switching the fastboot dip switch to on. I've attached the logs.

additional info: doing the same (without actually needing to do the fastboot switch turning on) i've successfully flashed the 1.4.5 on a starling v2!

@Viktor-Gal , it is possible that your OS is not correctly recognizing the fastboot USB device or there are insufficient permissions. 

While the board is in the fastboot mode (either using the dip switch or using `adb reboot bootloader`, which is called by the sdk install script), do you see a QCOM device when running `lsusb` ?

@Alex-Kushleyev as said above with the very same machine i successfully updated a starling v2 drone. but i'll try to check what you've just suggested.

@Viktor-Gal , yes please try to put the device into bootloader mode via a switch or using the `adb reboot bootloader` command and then checking if it's actually in bootloader mode:
`fastboot devices`
or
`sudo fastboot devices`

and also checking output of `lsusb`

@Alex-Kushleyev 

using the dip switch and powercycling there's no devices showing up with `sudo fastboot devices`.

unfortunately no `lsbusb` as i'm under macos, but sysprofiler's output is:
```
      Host Controller Driver: AppleT6000USBXHCI

        QUSB_BULK_CID:0412_SN:008A1847:

if you really think there's some extra info with lsusb that you are looking for i can hook it up to my raspberry pi.

@Viktor-Gal , I think we need some help form @tom :)

My guess is that OSX is not supporting fastboot for some reason, so you may want to try using native Linux, as that usually fixes most issues like this. QUSB_BULK device seems the correct one for the VOXL2 board that is in fastboot mode.

@Alex-Kushleyev you reckon? i mean the starling v2 just went to fastboot mode very nicely and i could flash it easily on the same macos. or is there so much of a difference between the starling v1 and v2 chips? i'll give it a go on the raspberry pi.

@Viktor-Gal , yes I understand what you are saying.

Just to double check, the older Starling boots fine when not in fastboot mode, right?

Please try on Linux OS just to double check anyway..

@Alex-Kushleyev yes yes, it boots up fine in normal mode

@Viktor-Gal We don't get too many test cycles on OSX so ideally you flash on a linux machine if possible.
