simulavr(1) Atmel AVR simulator


simulavr [OPTIONS]... -d DEVICE [IMAGE]


Simulate an avr device. The optional IMAGE file is loaded into the flash program memory space of the device.


-h, --help
Show this message
-D, --debug
Debug instruction output
-v, --version
Print out the version number and exit
-g, --gdbserver
Run as a gdbserver process
-G, --gdb-debug
Print out debug messages for gdbserver
-p, --port <port>
Listen for gdb connection on TCP port
-d, --device <dev>
Specify device type
-e, --eeprom-image <img>
Specify an eeprom image file
-E, --eeprom-type <type>
Specify the type of the eeprom image file
-F, --flash-type <type>
Specify the type of the flash image file
-L, --list-devices
Print supported devices to stdout and exit
-P, --disp-prog <prog>
Display register and memory info with prog
-X, --without-xterm
Don't start disp prog in an xterm
-C, --core-dump
Dump a core memory image to file on exit
-c, --clock-freq <freq>
Set the simulated mcu clock freqency (in Hz)
-B, --breakpoint <addr>
Set a breakpoint (address is a byte address)

If the image file types for eeprom or flash images are not given, the default file type is binary.

If you wish to run the simulator in gdbserver mode, you do not have to specify a flash-image file since the program can be loaded from gdb via the `load` command.

If '--port' option is given, and '--gdbserver' is not, port is ignored

If running in gdbserver mode and port is not specified, a default port of 1212 is used.

If using the '--breakpoint' option, note the simulator will terminate when the address is hit if you are not running in gdbserver mode. This feature not intended for use in gdbserver mode. It is really intended for testing the simulator itself, but may be useful for testing avr programs too.

Currently available device types:

Use the '--list-devices' option to obtain the list your version of simulavr supports.
