Re: [Paparazzi-devel] u-blox flashing with floss jtag

[Bruzzlee]

Hi Felix
Thx 4 the answer

I think (correct me if I'm wrong) I've already connected the gps to the 
jtag serial port by connecting it to the UART/COM.

I now tried the your method with the bridge (tunnel firmware).
The tunnel is ready but the orange led (RX) and the second blue led on 
the lisa board is blinking every second.
--> no difference.
I also tried to switch RX and TX but then, no led is blinking.

Thx Bruzzlee
