Hi TinyOS user,
Does someone have experience with JTAG debugging on Eclipse. I try to debug my
TinyOS Code with the Yeti2 Plugin and a JTAG adapter (avr dragon). I can
connect avarice with the target (ATMega 1281). The target replies the device id
and the type. The last message is: Waiting for connection on port 4242
JTAG config starting.
Found a device: AVRDRAGON
Serial number: 00:a2:00:00:28:4b
Reported JTAG device ID: 0x9704
Configured for device ID: 0x9704 atmega1281
JTAG config complete.
Preparing the target device for On Chip Debugging.
Disabling lock bits:
LockBits -> 0xff
Enabling on-chip debugging:
Extended Fuse byte -> 0xff
High Fuse byte -> 0x1c
Low Fuse byte -> 0xe2
Waiting for connection on port 4242.
Connection opened by host 127.0.0.1, port 58180.
.
.
.
The next step is to connect the debugger of the eclipse plug-in with the proxy
listening on port 4242 @ localhost. The selected debugger is avr-gdb.
The avr-gdb console shows all commands
.

673-break-insert MicaTimer.h:92

The problem is I can't set breakpoints successfully. In the code file in
eclipse there are warnings "Unresolved breakpoint". With the debug button I can
start the blink code on the controller but nothing happens with the breakpoints
and I can't monitor the register. The leds on the module starts blinking as
expected from the Blink example. The led on the JTAG adapter is flashing all
the time.
If I use the option of the Yeti2 debug setup "Use full file path to set
breakpoints" the the gdb error does not appear, but the breakpoint problem is
still the same.

I compiled the project with the debug option, so there should be debugging
symbols defined in the main.exe which is created by the compiler
