stm32_ex_ops

enum stm32_ex_ops

#include <include/zephyr/drivers/flash/stm32_flash_api_extensions.h>

Enumeration for STM32 flash extended operations.

Enumerator
FLASH_STM32_EX_OP_SECTOR_WP	STM32 sector write protection control. Attention Available only when the following Kconfig option is enabled: CONFIG_FLASH_STM32_WRITE_PROTECT . As an input, this operation takes a flash_stm32_ex_op_sector_wp_in with two sector masks: first mask is used to enable protection on sectors, while second mask is used to do the opposite. If both masks are 0, then protection will remain unchanged. If same sector is set on both masks, protection will be enabled. As an output, sector mask with enabled protection is returned. Input can be NULL if we only want to get protected sectors. Output can be NULL if not needed.
FLASH_STM32_EX_OP_RDP	STM32 sector readout protection control. Attention Available only when the following Kconfig option is enabled: CONFIG_FLASH_STM32_READOUT_PROTECTION . As an input, this operation takes a flash_stm32_ex_op_rdp with information about desired RDP state. As an output, the status after applying changes is returned.
FLASH_STM32_EX_OP_BLOCK_OPTION_REG	STM32 block option register. This operation causes option register to be locked until next boot. After calling, it's not possible to change option bytes (WP, RDP, user bytes).
FLASH_STM32_EX_OP_BLOCK_CONTROL_REG	STM32 block control register. This operation causes control register to be locked until next boot. After calling, it's not possible to perform basic operation like erasing or writing.
FLASH_STM32_EX_OP_OPTB_READ	STM32 option bytes read. Read the option bytes content, out takes a *uint32_t, in is unused.
FLASH_STM32_EX_OP_OPTB_WRITE	STM32 option bytes write. Write the option bytes content, in takes the new value, out is unused. Note that the new value only takes effect after the device is restarted.

stm32_qspi_ex_ops

enum stm32_qspi_ex_ops

#include <include/zephyr/drivers/flash/stm32_flash_api_extensions.h>

Enumeration for STM32 QSPI extended operations.

Enumerator
FLASH_STM32_QSPI_EX_OP_GENERIC_READ	QSPI generic read command. Transmit the custom command and read the result to the user-provided buffer.
FLASH_STM32_QSPI_EX_OP_GENERIC_WRITE	QSPI generic write command. Transmit the custom command and then write data taken from the user-provided buffer.
