Struct imxrt_boot_gen::flexspi::LookupTable

pub struct LookupTable(/* private fields */);

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());
