Load a program into the flash via JTAG ICE and AVR Studio automatically erases the whole Flash. That's fine if you have one piece of code, but is a mess if you play around with code sharing between bootloader and application. Programming via ISP gives the opportunity to select if the flash should be erased completely or not. Is there a way to prevent erasing of the whole flash while prgramming via JTAG and AVR Studio?
If I did not miss any switch is this feature a need by the CPU Hardware (Jtag I/F) or is it still not implemented in the AVR Studio?
