Package: gdb-avr
Version: 6.4.90.dfsg-3
Severity: normal
Tags: squeeze
When using avr-gdb with eclipse to debug an avr-program from the IDE, gdb
encounters an internal error. This makes debugging directly from eclipse
impossible.
Steps to reproduce:
Install eclipse
Install CDC and AVR plugins
Setup avarice as external program in eclipse with following options:
arguments:
-2 --ignore-intr --jtag usb localhost:4242 -B 1500KHz
Setup avr-gdb as hardware debugger in eclipse with following options:
Protocol version: mi
Verbose console mode
Use remote target
Reset and delay = 3
Halt
Load symbols
Set breakpoint at: main
Resume
Connect JTAG ICE mkII
Compile some example program for the avr and flash it
Start avarice from eclipse
Start gdb from eclipse
The output produced by eclipse is a follows:
