In the STM32CubeWBA firmware package, the OEMiRoT & OEMiRoT_OEMuRoT examples are not provided for all boards and all MCUs. This article explains how to generate the OEMiROT examples for the NUCLEO-WBA65RI and NUCLEO-WBA55CG boards, as well as OEMiROT & OEMiRoT_OEMuRoT examples for the STM32WBA55G-DK1 board.

1. OEMiRoT projects creation for NUCLEO-WBA65RI

OEMiRoT example can be generated for the NUCLEO-WBA65RI board using the STM32WBA65I-DK1 board as a reference. To do that, follow the steps below:

1.1. Get the source files from the STM32WBA65I-DK1 board:

Copy the Projects/STM32WBA65I-DK1/Applications/ROT/OEMiROT_Appli content in Projects/NUCLEO-WBA65RI/Applications/ROT/OEMiROT_Appli
Copy the Projects/STM32WBA65I-DK1/Applications/ROT/OEMiROT_Appli_TrustZone content in Projects/NUCLEO-WBA65RI/Applications/ROT/OEMiROT_Appli_TrustZone
Copy the Projects/STM32WBA65I-DK1/Applications/ROT/OEMiROT_Boot content in Projects/NUCLEO-WBA65RI/Applications/ROT/OEMiROT_Boot

1.2. Change the board name in the project files :

Following your preferred IDE, update the project files replacing STM32WBA65I-DK1 to NUCLEO-WBA65RI
