Uploading code with Energia 17 on Fedora 23 x64 and Windows 10 x64 do not work using the latest Wifi Micro bootloader.

I'll get an error when uploading compiled binary like this:

Using HID to reset for RedBearLab board
Open UART /dev/ttyACM0
open UART success
Triggering bootloader....
UART Receive Timeout
Trigger bootloader failed. Retrying... (1 attempt)
UART Receive Timeout

Found RedBearLabs board
Trigger bootloader failed after 3 attempts
Get mk20 version response : 0xe5
Get mk20 version len : 0x12
Get mk20 version string : MK20.CC3200.V1.0.
Failed to trigger bootloader

Resetting RedBearLabs board
Get reset response : 0xe5 0x00

I can verify that the bootloader has been installed correctly by hexediting the version string of the bootloader binary before flashing and making sure that it is printed by energia.
