Code Updating
To update the code in the OPS241, follow the step by step instructions which follow. You should have a
JTAG programming tool like the miniWiggler or Seggar noted above.
Step 1.
Download and install the Memtool programming tool from the Infineon website. Follow the
installation instructions that come with the download.
Step 2.
Connect the JTAG programming tool connector to the JTAG connector on the OPS241 (J6) located
in near the middle of the board (Figure 3). The connector is keyed, so it can only connect in one direction.

Step 3.
Plug in the USB connector of the JTAG programmer to a USB port on the PC. Plug in a USB micro
cable into the OPS241 and the other end into another USB port on the PC (Figure 4). This provides power
to the OPS241 during the program update.
