This sequence can be sent using a script built with FlexGUI. See Section 8.3.2 "Script

sequence files".

7.3 Programming the device with an OTP configuration

The device configuration can be changed three times (see Section 4.2.1 "OTP and

mirrors registers"). The programming steps are exactly the same as the OTP emulation

mode up to step 6.

Then, the user has to burn the part with FlexGUI. See Section 8.4.8 "OTP programming".

Follow the instructions on the screen to proceed.

8 Using FlexGUI

To follow the steps in this section, make sure that the board is connected using the

appropriate hardware configuration (see Section 7.2 "Working in OTP emulation mode").

Note: It is recommended to use the latest version of FlexGUI.

8.1 Starting the FlexGUI application

After FlexGUI is launched with the flexgui-app.bat file, the FlexGUI launcher displays

available kits.

Communication bus, SPI or I2C can be selected at this level. It is also possible to switch

from one to the other using the communication tab from the main panel (see Section 8.2

"Establishing the connection between FlexGUI and the hardware").
