Struct embassy_rp::block::Block

#[repr(C)]
pub struct Block<const N: usize> { /* private fields */ }

A Block as understood by the Boot ROM.

This could be an Image Definition, or a Partition Table, or maybe some other kind of block.

It contains within the special start and end markers the Boot ROM is looking for.

Implementations

impl<const N: usize> Block<N>

pub const fn new(items: [u32; N]) -> Block<N>

Construct a new Binary Block, with the given items.

The length, and the Start and End markers are added automatically. The Block Loop pointer initially points to itself.

pub const fn with_offset(self, offset: *const u32) -> Block<N>

Change the Block Loop offset value.

This method isn’t that useful because you can’t evaluate the difference between two pointers in a const context as the addresses aren’t assigned until long after the const evaluator has run.

If you think you need this method, you might want to set a unique random value here and swap it for the real offset as a post-processing step.

impl Block<0>

pub const fn empty() -> Block<0>

Construct an empty block.

pub const fn extend(self, word: u32) -> Block<1>

Make the block one word larger

impl Block<1>

pub const fn extend(self, word: u32) -> Block<2>

Make the block one word larger

impl Block<2>

pub const fn extend(self, word: u32) -> Block<3>

Make the block one word larger

impl Block<1>

pub const fn arch_exe(security: Security, architecture: Architecture) -> Self

Construct a new IMAGE_DEF Block, for an EXE with the given security and architecture.

pub const fn exe(security: Security) -> Self

Construct a new IMAGE_DEF Block, for an EXE with the given security.

The target architecture is taken from the current build target (i.e. Arm or RISC-V).

pub const fn non_secure_exe() -> Self

Construct a new IMAGE_DEF Block, for a Non-Secure EXE.

The target architecture is taken from the current build target (i.e. Arm or RISC-V).

pub const fn secure_exe() -> Self

Construct a new IMAGE_DEF Block, for a Secure EXE.

The target architecture is taken from the current build target (i.e. Arm or RISC-V).
