Hello.

I made a target board with XMC4500 and it has a 10-pin debugger connection like XMC4500 Relax Lite Kit debugger port.

I want to secure chip this target board from flash read-out.
Is it possible If I use Memtool and DAP Miniwiggler V3?

Regards.

Hi ahndy,

You can follow the steps in the power point slides.

The password and procedures are quite sensitive, hence please take special care on these. If possible have a socket for your MCU, in the event of MCU lockout you do not have to waste a target board.

Lastly please note that changing the password will cause the erase of the UCB which had a limited number of time (10 times).

Hi Travis.

Thank you for your answer.

My target board has Jtag/SWD port only.
In order to write the flash with Memtool what interface is needed.
I am inrend to buy a Miniwiggler V3.

Best regards.

Hi,

The memtool works on ASC/UART. Current Infineon boards (Relax kit or Application board) already has this feature built in. Should you need to have an interface between the PC (USB) and your own target board (UART) you can consider using FTDI chip which create a virtual COM Port.
