Flash and ISP specification
To issue a command to BatchISP, right-click in the ‘AVR32 Targets’ pane the AVR32 target to
use and select a command:
All GCC and IAR projects in the AVR UC3 software framework are set up so that they can be
programmed with both JTAGICE mkII and BatchISP. To achieve this, a trampoline section is
placed at the reset vector (80000000h). This section simply jumps to the beginning of the appli-
cation (80002000h).
To program an application with JTAGICE mkII, the MCU flash array must first be unprotected
and erased, so the bootloader should be removed. When programming, the whole binary image
including the trampoline and the application, is copied to the flash array. Consequently, when
MCU execution is then started, the trampoline executes at the reset vector at 80000000h and
jumps to the application at 80002000h.
