Tested patch v2 from 2010-04-02 now for atmega2560 on avrtest simulator. In main, var1 and var2 are initialized as expected and anObject.getVal() is 30. Without patch the program hangs. > Using avr-gdb-7.2 to debug with stubs runs on errors and doesn't show > me any code... no assembly with "A syntax error in expression, near > `0x29c'" in assembly window. > Trying to compile with avr-gcc and dwarf crashes avr-gcc. > > __do_copy_data fails to initialize var1 and var2 (are 0x0). Seems atmega2560 is not supported in avr-gdb-7.2 simulator? Same elf fails to initialize .data. Do you know for which targets avr-gdb is supposed to work? Johann
