The query requests support for STM32WBAxx MCUs (specifically STM32WBA6), while the candidate PR adds support for STM32WB MCUs (specifically NUCLEO_WB55). Although both are from the same STM32 wireless MCU family (WB vs WBA), they are different chip families with different hardware specifications. The PR addresses bootloader support for WB chips, but does not implement the full MCU support requested for WBA chips. The WBA series has different peripherals, memory maps, and requirements compared to the WB series, so this PR does not resolve the query.
Suggested action
Keep both items open. The PR provides useful context for STM32 wireless MCU support but does not address the specific WBA6 request. Consider linking the PR to the issue as related work, but the issue remains open for WBA-specific implementation.
