imxrt-rs/imxrt-ral: Register Access Layer for i.MX RT Microcontrollers

A Rust register access layer (RAL), and SVD patches for NXP i.MX RT processors.

API Docs (main branch)

• Simple but useful register level access. It compiles quickly, and it's intuitive for existing embedded developers.
• RTIC support.

The imxrt-ral is a lower-level interface for i.MX RT processor registers with useful macros. The imxrt-ral is modeled after the stm32ral crate. It provides direct access to the processor's registers. Use the imxrt-ral if you'd like to create your own hardware abstraction layer, or a custom driver.

The imxrt-ral supports these i.MX RT processors:

• "imxrt1011"
• "imxrt1015"
• "imxrt1021"
• "imxrt1051"
• "imxrt1052"
• "imxrt1061"
• "imxrt1062"
• "imxrt1064"
• "imxrt1176_cm4"
• "imxrt1176_cm7"
• "imxrt1189_cm33"
• "imxrt1189_cm7"

The RAL also requires a feature flag to specify the processor variant. The RAL is on crates.io. The RAL provides the "rt" feature flag, and the interrupt table definition, that's used by the HAL.

See here and here. svd2rust generates a crate that's nearly 1 million lines of Rust code, and it takes a few minutes to compile. On the other hand, the RAL compiles in a few seconds. Additionally, svd2rust only supports one SVD input, but the RAL auto-generation script accepts multiple SVD inputs, sharing the common peripherals across processor families. This means that we can more easily support all i.MX RT processor variants from a single crate.
