BatchISP is a command line tool that allows to program parts containing an embedded Atmel
ISP. It comes with FLIP 3. See Section 3 for download information.
To install BatchISP, first install FLIP 3 using its installer, then connect a part to the PC using a
USB cable and activate the ISP as described in Section 7.2. For instance, with the default con-
figuration on EVK1100 or EVK1101, press the reset push-button, then maintain the joystick
pressed while releasing the reset push-button. This will open a new hardware installation win-
dow. Choose not to connect to Windows Update for this installation and click ‘Next’:
For each Byte of the ISP configuration word, issue the following commands (using the
computed ISP configuration word from step 4 (0x929F58D2)):
