STM32WBA63CUI7 OEM ROT Porting Help

[nomancy]

I'm porting OEM ROT examples from STM32WBA65I-DK1 to STM32WBA63CUI7 and need guidance.

Devices:

- Target: STM32WBA63CUI7 (2MB flash, CSP17)
- Source: STM32WBA65I-DK1 (2MB flash, UFBGA169)

Questions:

1. Device Support: Any known STM32WBA63xx definition gaps for OEM ROT?
2. Package Differences: CSP17 vs UFBGA169 considerations for GPIO/clocks/security?
3. Memory Layout: Any subtle differences despite identical 2MB dual-bank flash?
4. Build Integration: Best way to add STM32WBA63xx to STM32CubeIDE projects?
5. BSP: Need custom BSP or can adapt existing ones?

Any insights or similar experiences appreciated!

Thanks!

Hello @nomancy ,

The WBA63 just misses USB and has less UART/I2C/SPI compared to WB65, so nothing to change except the adaptation of the UART trace to your own board.

In case you need to use external SPI for download slot, you may also need to adapt the interface to your board.

Best regards
