Struct Descriptor 

pub struct Descriptor {
    pub start: u32,
    pub image_len: u32,
    pub file_len: u32,
    pub flash_op_type: u8,
    /* private fields */
}

The card’s reply to upgrade_info: image geometry and upgrade capabilities.

Fields

start: u32

Flash address the image starts at.

image_len: u32

Bytes programmed into flash.

file_len: u32

Required source-file size, including trailing padding.

flash_op_type: u8

Type byte for direct flash operations.

Implementations

impl Descriptor

pub const fn supports_sdram(self) -> bool

The card can stage an image in SDRAM and program itself.

pub const fn has_golden(self) -> bool

The card keeps a golden backup image.

pub const fn supports_select_part(self) -> bool

The card accepts a partition selection.

pub const fn supports_golden_upgrade(self) -> bool

The card accepts upgrades aimed at the golden bank.

pub const fn chunks(self) -> usize

Chunks needed to stage an image of this size.

pub const fn first_poll_ms(self) -> u64

Vendor delay before the first completion poll: 150 ms per 64 KiB block, at least 1000 ms (timings_match_the_vendor_formulas).

pub const fn estimated_ms(self) -> u64

Vendor estimate of programming time: 500 ms per 64 KiB block plus 3 ms per 256-byte page.
