MacOS X: Cannot read Taranis TX

[amelluk]

I'm stumped. I cant get C9X 1.47 and dfu-util 0.7 to read my Taranis firmware. Hope someone knows where the problem is:

a) Taranis is mounted on Mac, I can see the flash storage card

b) Taranis USB device is visible on Mac system information:

FrSky Taranis Mass Storage:

Product ID: 0x5720
Vendor ID: 0x0483 (STMicroelectronics)
Version: 2.00
Serial Number: 00000000001B
Speed: Up to 12 Mb/sec
Manufacturer: FrSky
Location ID: 0xfd140000 / 5

c) dfu-util will not recognise the TX when run from C9x

Any ideas? Please

To use the DFU, plug the USB in with the Tx switched off.

If mass storage is visible, it means that radio is turned on...
consequently DFU is not visible.... you need to connect the radio turned off to upgrade/read the firmware.
I clearly written in the online manual: http://code.google.com/p/opentx/wiki/Op ... c_concepts

An important thing to understand is how things are stored on the radio. We will regularly talk of 2 different types of memories, Flash and EEPROM.

Flash is the memory where the radio's firmware or "operating system" resides. "Flashing the radio" means replacing the firmware, which you would usually do either to upgrade to a newer version or to change language. Models and settings are not affected when flashing the firmware. On the Taranis, flashing is done with the radio OFF. So turn the radio off, then plug it to the computer's USB port.
EEPROM is the separate settings/model memory. Reading it allows backing up and editing in companion9x, writing it sends the result of the edits back to the radio. On the Taranis, this is done with the radio ON. Turn it on, dismiss any warnings in order to get to the main views, then plug the USB cable. You will see two USB drives appear, one is the SD card, and one is the EEPROM virtual drive.
