A flash manager thread is created and allocated to process Flash Manager Process. Definition of KConfigs STM32WBA_FLASH_MNGR_THREAD_STACK_SIZE, and STM32WBA_FLASH_MNGR_THREAD_PRIO to configure the flash manager thread. STM32WBA_FLASH_MNGR_THREAD_STACK_SIZE is setting by default to 768 bytes. This value was chosen empirically since reasonable to cover generic cases.

DETAILS AND LIMITATIONS.

When this option is enabled, unaligned writes will be handled by writing to all blocks in range
|
|
[offset; offset + length]. Blocks for which only part of the contents are provided are padded with
|
|
the flash's erase value before writing. THIS IS NOT A READ-MODIFY-WRITE type operation! The flash
|
|
addresses being written to are expected to be erased before writing to them. Contens of the flash
|
|
after unaligned writes depend on the flash hardware details. The operation may fault.
