... There is one bootloader compiled for each AVR UC3 serie. The hardware I/O conditions used to request the start of the ISP are also specific to each serie. This document describes the USB bootloader functionalities and its usage in various contexts. 2.

... The conditions tested by the boot process are configured by the general-purpose fuse bits located outside of the MCU address space and by a 32-bit configuration word located at the end of the flash User page. Figure 6-1. AT32UC3A0512 Non-Volatile Memory Layout with USB DFU Bootloader 6.2 Configuration The bootloader has a configuration which determines the behavior of the boot process and of the ISP ...

... The GPIO pin number to test during the boot process to know which of the USB DFU ISP and the application to start. E.g., to select PX16 (i.e. QFP144 pin 61 and the GPIO pin 88) on AT32UC3A0512, this bit-field has to be set to 88. Possible values are 109 for AVR UC3 A0 QFP144; ...

If external events (power-on reset, external reset, OCD reset, JTAG reset or JTAG hardware reset) are among the reset causes, the boot process checks if the ISP_IO_COND_EN GP fuse bit is 1, and ...

If the ISP_FORCE GP fuse bit is 0 and the user has set the ISP_IO_COND_EN GP fuse bit to 0, the ISP will no longer be reachable, except if the programmed application sets the ISP_FORCE GP fuse bit to ...

... As mentionned in Table 6-4. the ISP_IO_COND_PIN field is placed at offset 8 of the ISP config- uration word and contains the GPIO pin number the boot process will test example, we’ll use PX16 on AT32UC3A0512 (i.e. QFP144 pin 61 so GPIO pin 88 (i.e. 0x58 in hexadecimal representation) and assume a high level condition (cf step 2): the ISP con- figuration word is then 0x929F58** ...

Once completed, click ‘Finish’: This installation has to be done for each new part family to use. E.g., using an AT32UC3A0512 then an AT32UC3A0256 will not require a new installation, but then connecting an AT32UC3B0256 will ...

... The AT32UC3xxxxx memories made available by BatchISP are: • FLASH protected area. E.g. on AT32UC3A0512 (512-kB internal flash), addresses from 0 to 0x7FFFF can be accessed in this memory. • SECURITY the value of the target Security bit which can only be set to 1. Once set, the only accepted commands will be until the end of the non-volatile ISP session, even if the Security bit is set ...

... 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 ...

This requires the generation of an Intel HEX extra output file: Once an application has been programmed using BatchISP, it can still be debugged with JTAGICE mkII in the usual way. This is especially interesting for large applications because 7745C–AVR32–05/09 ...
