[Paparazzi-devel] Telemetry over FLOSS-JTAG

I'm currently attempting to get telemetry data from Lisa/M via the
FLOSS-JTAG. I would've referenced the wiki, but ENAC is offline for
the night updating. The board is being powered by the onboard MicroUSB
port connected to my laptops' USB port. The wiring is as follows:

JTAG GND is connected to UART2 GND
JTAG RX is connected to UART2 TX
JTAG TX is connected to UART2 RX
JTAG 5V is not connected as the board is being powered by the MicroUSB
port and JTAG is being powered by it's own USB port.

I've got the telemetry set as transparent in the airframe config and
am on the most up to date dev build. I got this idea after watching
Piotr's video of the manufacturing process when he tests the baro. I
opened up the data link at 57600 baud and it is set as so in the
airframe config (it's actually not set in the airframe config, but
57600 is the default for telemetry.) The messages app remains blank
and the GCS is blank just as if the board isn't powered on (but it
is.) The power LED is glowing steadily per usual and the other clock
LED is blinking at 1 Hz. Has anyone gotten telemetry data over the
FLOSS-JTAG before?
