use the S3(PA13) to make CPU return to boot status. In this mode, the
|

on chip bootloader will run, making the ISP possible.

|
||||
BatchISP
|
||||
--------
|
||||
|
||||
Unlike other Atmel parts, the AVR32 will not work with the FLIP GUI
|
||||
program. Instead, you must use the command-line loader call BatchISP.
|
||||
If need to download FLIP from the atmel.com website, install the USB
|
||||
driver in the FLIP usb directory. Then in the bin directory where
|
||||
you installed FLIP, you will also find batchisp.exe.
|
||||
|
||||
NOTE: The AVR32DEV1 setenv.sh files will add the path to the BatchISP
|
||||
bin directory to the Cygwin PATH variable. If you use a different
|
||||
version of FLIP or if you install FLIP in a different location, you
|
||||
will need to modify the setenv.sh files.

Notes from "AVR32 UC3 USB DFU Bootloader" (doc7745.pdf)
|
||||
|
||||
"To launch BatchISP, open a command prompt. Windows or Cygwin command
|
||||
prompt can be used provided that the bin folder of the FLIP installation
|
||||
directory is in the PATH (Windows’ or Cygwin’s) environment variable.
|
||||
When running BatchISP on AT32UC3xxxxx, the target part has to be specified
|
||||
with -device at32uc3xxxxx and the communication port with -hardware usb.
|
||||
Commands can then be placed after -operation. These commands are executed
|
||||
in order. BatchISP options can be placed in a text file invoked using
|
||||
-cmdfile rather than on the command line.
|
||||
|
||||
"BatchISP works with an internal ISP buffer per target memory. These ISP
|
||||
buffers can be filled from several sources. All target operations (program,
|
||||
verify, read) are performed using these buffers.
|
||||
|
||||
"A typical BatchISP command line programming an application will look like
|
||||
this:"
|
||||
|
||||
[For the NuttX ELF file and the AT91UC3B0256 part:]
|
||||
|
||||
batchisp -device at32uc3b0256 -hardware usb -operation erase f memory flash \
|
||||
blankcheck loadbuffer nuttx program verify start reset 0
|
||||
|
||||
"BatchISP main commands available on AT32UC3xxxxx are:
|
||||
|
||||
- ASSERT { PASS | FAIL } changes the displayed results of the following
|
||||
operations according to the expected behavior.
|
||||
- ONFAIL { ASK | ABORT | RETRY | IGNORE } changes the interactive behavior
|
||||
of BatchISP in case of failure.
|
||||
- WAIT <Nsec> inserts a pause between two ISP operations.
|
||||
- ECHO <comment> displays a message.
|
||||
- ERASE F erases internal flash contents, except the bootloader.
|
||||
- MEMORY { FLASH | SECURITY | CONFIGURATION | BOOTLOADER | SIGNATURE | USER }
|
||||
selects a target memory on which to apply the following operations.
|
||||
- ADDRANGE <addrMin> <addrMax> selects in the current target memory an
|
||||
address range on which to apply the following operations.
|
||||
- BLANKCHECK checks that the selected address range is erased.
|
||||
- FILLBUFFER <data> fills the ISP buffer with a byte value.
|
||||
- LOADBUFFER { <in_elffile> | <in_hexfile> } loads the ISP buffer from an
|
||||
input file.
|
||||
- PROGRAM programs the selected address range with the ISP buffer.
|
||||
- VERIFY verifies that the selected address range has the same contents
|
||||
as the ISP buffer.
|
||||
- READ reads the selected address range to the ISP buffer.
|
||||
- SAVEBUFFER <out_hexfile> { HEX386 | HEX86 } saves the ISP buffer to an
|
||||
output file.
|
||||
- START { RESET | NORESET } 0 starts the execution of the programmed
|
||||
application with an optional hardware reset of the target.
|
||||
|
||||
"The AT32UC3xxxxx memories made available by BatchISP are:
|
||||
|
||||
- FLASH: This memory is the internal flash array of the target, including the
|
||||
bootloader protected area. E.g. on AT32UC3A0512 (512-kB internal flash),
|
||||
addresses from 0 to 0x7FFFF can be accessed in this memory.
|
||||
- SECURITY: This memory contains only one byte. The least significant bit
|
||||
of this byte reflects the value of the target Security bit which can only
|
||||
be set to 1. Once set, the only accepted commands will be ERASE and START.
|
||||
After an ERASE command, all commands are accepted until the end of the
|
||||
non-volatile ISP session, even if the Security bit is set.
|
||||
- CONFIGURATION: This memory contains one byte per target general-purpose
|
||||
fuse bit. The least significant bit of each byte reflects the value of
|
||||
the corresponding GP fuse bit.
|
||||
- BOOTLOADER: This memory contains three bytes concerning the ISP: the ISP
|
||||
version in BCD format without the major version number (always 1), the
|
||||
ISP ID0 and the ISP ID1.
|
||||
- SIGNATURE: This memory contains four bytes concerning the part: the product
|
||||
manufacturer ID, the product family ID, the product ID and the product
|
||||
revision.
|
||||
- USER: This memory is the internal flash User page of the target, with
|
||||
addresses from 0 to 0x1FF.

help files installed with FLIP ..."
