Flash and ISP specification
Windows will then process the installation of the driver corresponding to the ISP of the con-
nected part. 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.
To launch BatchISP, open a command prompt. Windows or Cygwin command prompt can be
used provided that the
Cygwin’s) environment variable.
When running BatchISP on AT32UC3xxxxx, the target part has to be specified with
at32uc3xxxxx
after
text file invoked using
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:
batchisp -device at32uc3a0512 -hardware usb -operation erase f memory flash
blankcheck loadbuffer uc3a0512-usart_example.elf program verify start reset 0
-operation
and the communication port with
. These commands are executed in order. BatchISP options can be placed in a
-cmdfile
bin
folder of the FLIP installation directory is in the
rather than on the command line.

. Commands can then be placed
