Expand description

A flash algorithm, which has been assembled for a specific chip.

To create a FlashAlgorithm, call the assemble_from_raw function.

Fields§

§name: String

The name of the flash algorithm.

§default: bool

Whether this flash algorithm is the default one or not.

§load_address: u64

Memory address where the flash algo instructions will be loaded to.

§instructions: Vec<u32>

List of 32-bit words containing the position-independent code for the algo.

§pc_init: Option<u64>

Address of the Init() entry point. Optional.

§pc_uninit: Option<u64>

Address of the UnInit() entry point. Optional.

§pc_program_page: u64

Address of the ProgramPage() entry point.

§pc_erase_sector: u64

Address of the EraseSector() entry point.

§pc_erase_all: Option<u64>

Address of the EraseAll() entry point. Optional.

§static_base: u64

Initial value of the R9 register for calling flash algo entry points, which determines where the position-independent data resides.

§begin_stack: u64

Initial value of the stack pointer when calling any flash algo API.

§page_buffers: Vec<u64>

A list of base addresses for page buffers. The buffers must be at least as large as the region’s page_size attribute. If at least 2 buffers are included in the list, then double buffered programming will be enabled.

§rtt_control_block: Option<u64>

Location of optional RTT control block.

If this is present, the flash algorithm supports debug output over RTT.

§flash_properties: FlashProperties

The properties of the flash on the device.

§transfer_encoding: TransferEncoding

Implementations§

source§

impl FlashAlgorithm

source

pub fn sector_info(&self, address: u64) -> Option<SectorInfo>

Try to retrieve the information about the flash sector which contains address.

If the address is not part of the flash, None will be returned.

source

pub fn page_info(&self, address: u64) -> Option<PageInfo>

Returns the necessary information about the page which address resides in if the address is inside the flash region.

source

pub fn iter_sectors(&self) -> impl Iterator<Item = SectorInfo> + '_

Iterate over all the sectors of the flash.

source

pub fn iter_pages(&self) -> impl Iterator<Item = PageInfo> + '_

Iterate over all the pages of the flash.

source

pub fn is_erased(&self, data: &[u8]) -> bool

Returns true if the entire contents of the argument array equal the erased byte value.

source

pub fn get_max_algorithm_header_size() -> u64

When the target architecture is not known, and we need to allocate space for the header, this function returns the maximum size of the header of supported architectures.

source

pub fn assemble_from_raw( raw: &RawFlashAlgorithm, ram_region: &RamRegion, target: &Target ) -> Result<Self, FlashError>

Constructs a complete flash algorithm, tailored to the flash and RAM sizes given.
