[Solved] Firmware update on REX yields "Failed to get device info"

[mar]

I’m trying to update the firmware on my REX, but I’m apparently not connecting to the device. I have the REX plugged into the USB port on my PC, which is running Arch Linux.

My fwupgrade command outputs a 202 error. Can anyone advise me how to troubleshoot this?

$ cd TobiiGazeSdk-CApi-4.1.0.806-linux64/tools/
$ LD_PRELOAD=libcurl.so.3 ./fwupgrade tobii-ttp://REXDL-030114044623  

#output:
/home/markham/Downloads/rexdevlaptop_firmware_1.2.4.33069.20150521.1055.root.tobiipkg
./fwupgrade: /usr/lib/libcurl.so.3: no version information available (required by ./fwupgrade)
Tobii Firmware Upgrade Tool
Valid Tobii package for g5
202 Error in data from device
Failed to get device info

Hi @marr,

The drivers for Linux are not as mature as those for Microsoft Windows. If you need to upgrade the firmware on the device, I would recommend you connect the unit to a Windows machine, upgrade firmware and return to your linux setup.

Thanks, @Grant. Windows worked.
