Struct LookupTable

Source
pub struct LookupTable(/* private fields */);
Expand description

A sequence lookup table, part of the general FlexSPI configuration block

The contents of the sequences depend on what kind of FLASH device we’re interfacing. Refer to your FLASH device manual for more information.

Any unspecified command is set to a sequence of STOPs.

use imxrt_boot_gen::flexspi::{
    LookupTable,
    Command,
    SequenceBuilder,
    Sequence, Instr,
    opcodes::sdr::*,
    Pads,
};

const LUT: LookupTable = LookupTable::new()
    .command(Command::Read, SequenceBuilder::new()
        .instr(Instr::new(CMD, Pads::One, 0xEB))
        .instr(Instr::new(RADDR, Pads::Four, 0x02))
        .build());

Implementations§

Source§

impl LookupTable

Source

pub const fn new() -> Self

Create a new lookup table. All memory is set to zero.

Source

pub const fn command(self, cmd: Command, sequence: Sequence) -> Self

Assign the sequence to the command that is found at the Command index

Source

pub const fn custom_command(self, index: usize, sequence: Sequence) -> Self

Assign a sequence to one of the freely-available LUT indexes.

You’re responsible for making sure this doesn’t accidentally overwrite one of the standard Command sequences.
