Figure 7-2. Application Programming on AT32UC3A0512 with JTAGICE mkII
To program an application with BatchISP, the MCU flash array must contain the bootloader.
When programming, BatchISP takes into consideration the whole binary image including the
trampoline and the application, but the trampoline cannot overwrite the bootloader, so the tram-
poline is not programmed and a warning is issued by BatchISP to tell the user that the binary
image may contain an application linked directly at the reset vector without trampoline. Conse-
quently, when MCU execution is then started, the bootloader executes at the reset vector at
80000000h and launches the application at 80002000h when the required conditions are met.
