This README file discusses the issues involved with using the simulator
|
||
|
|
remotely from gdb.
|
||
|
|
|
||
|
|
First off, you will need to compile gdb >= 5.2.1 with the avr target support.
|
||
|
|
|
||
|
|
Once you've built and installed gdb for avr, you need to know how to use it to
|
||
|
|
debug a remote program. It's an easy, two step process. First, you need to
|
||
|
|
start up simulavr in gdbserver mode as such:
|
||
|
|
|
||
|
|
$ simulavr --gdbserver [other options]
|
||
|
|
|
||
|
|
Second, just start up avr-gdb with an avr elf program, connect to the remote
|
||
|
|
target, and load the program into the sim with these commands:
|
||
|
|
|
||
|
|
$ avr-gdb myprog.elf
|
||
|
|
(gdb) target remote localhost:<port>
|
||
|
|
(gdb) load
|
||
|
|
|
||
|
|
where <port> is the port number that simulavr is listening on. You need to
|
||
|
|
have the simulavr running before giving gdb the target command. In most cases,
|
||
|
|
you'll be running simulavr on the same host as gdb, thus the "localhost"
|
||
|
|
part. You must use the same port number for simulavr and in the gdb target
|
||
|
|
command. If you feel the need to run simulavr on another host, just change
|
||
|
|
localhost to the name of the host that simulavr will be running on.
|
||
|
|
|
||
|
|
After gdb has connected to the remote target, you should be able to use gdb
|
||
|
|
just as if you were debugging a program natively.
