imxrt-boot-gen

Generate i.MX RT boot-time data structures.

API docs (main branch)

Rationale

i.MX RT processors require certain data structures in order to configure FlexSPI and SEMC peripherals. The data structurs must be placed in a certain region of memory, with values that describe how a peripheral should interact with that memory. The data structures only support certain values, and need a particular layout in order to boot the system.

The imxrt-boot-gen crate helps you generate data structures to boot i.MX RT processors. As of this writing, the API supports

serial NOR flash

Other configurations, like NAND flash and parallel SEMC, may be added in the future.

Usage

Add imxrt-boot-gen to your dependencies, and select your processor with a feature flag:

[dependencies]
imxrt-boot-gen = { features = ["imxrt1060"] }

The entire API is const. You may define your data structures at compile time, and assign the values to static memory in your embedded program.

See the module-level documentation for more information about the API.

Features

The crate requires a feature selection. Features correlate to i.MX RT processor families. The supported features are listed below.

"imxrt1010"
"imxrt1060"
"imxrt1064"
