[Paparazzi-devel] No Data Link

[Daniel Bedenko]

Hello everyone, Datalink issue is unresolved. The issue is there are
no messages, GCS not populating.

What some of you have suggested is: you are using the wrong UART, your
baud rate is wrong, your xbees are in API mode, xbee is not on
ttyusb0, remove the Datalink section from your aircraft file, update
cvs, remove Braille TTY ..

what I have done is:
0) removed Braille TTY
1) Confirmed UART1 (tiny 2.11)
2) I have since removed the xbee from the equation and am connecting
directly to the pc via FDTI cable from the tiny 2.11
3) I have confirmed that the tiny is 100% on /dev/ttyUSB0 (i run
cutecom on dev/ttyUSB0, and binary data stops when the tiny turns off)
4) commented the DATALINK from airframe file
5) updated by:

   a)   cvs -z3 -d:pserver:address@hidden:/sources/paparazzi
co paparazzi3
   b)   cd ~/paparazzi3 && make
   (  no errors were generated. )


Tiny flashes, led1 starts and data starts to come in on ttyusb0, radio
works, (royal evo) google fill works :) there are no error messages in
paparazzi Center.  But GCS is empty, no messages coming through. any
other suggestions?
