sorry I did't mention that with gdb I already used .elf. But even with it
it does not work in simulavr. Is it because of .text base address ? I
assume that RAM variables are placed at addresses displayed in a .map file
and this info is held in an .elf file ?
We used following linker options:
LDFLAGS = -Wl,-Map=$(TARGET).map,--cref,--defsym,__stack=0x10FF \
-nostartfiles -nodefaultlibs -Ttext=0x01FC00
Is there a line utility capable of burning code via JTAG ? I searched
stk500 (used by avr-studio) and there are JTAGICE devices. (I am able to
"upload" via avr-studio but not via stk500.)
