Detailed Description

Strategy module for finding flash erase sector numbers when the sectors are different sizes.

Constructor & Destructor Documentation

◆ FlashVariableSectors()

constexpr FlashVariableSectors::FlashVariableSectors ( uint32_t * bank_config )

inlineconstexpr

bank_config is an array of uint32 addresses, containing the start of each sector.

The sector number is the index in this array. As a sentinel, the element after the last shall be 0xfffffffful.

Definition at line 78 of file Stm32Flash.hxx.

Member Function Documentation

◆ lookup_sector()

std::pair< unsigned, uint32_t > FlashVariableSectors::lookup_sector ( uint32_t addr )

inline

Lookup the next sector for an address, and return the {sector number, address} pair.

Definition at line 110 of file Stm32Flash.hxx.

◆ next_sector_address()

uint32_t FlashVariableSectors::next_sector_address ( uint32_t addr )

inline

Aligns an address to the next possible sector start (i.e., rounds up to sector boundary).

Parameters

addr	an address in the flash address space.

Returns: If addr is the first byte of a sector, then returns addr unmodified. Otherwise returns the starting address of the next sector.

Definition at line 87 of file Stm32Flash.hxx.

Member Data Documentation

◆ bankConfig_

uint32_t* FlashVariableSectors::bankConfig_

private

Contains an array of the start addresses of the erase sectors.

Definition at line 123 of file Stm32Flash.hxx.

◆ lastIndex_

unsigned FlashVariableSectors::lastIndex_ {0}

protected

1-element cache on where to start looking for sectors.

bankConfig_[lastIndex_] <= last address that was queried.
