# Changelog
## [Unreleased]
Establish a 32 byte reservation at the start of ITCM where instructions are
never placed. This reduces the total capacity of ITCM by 32 bytes on nearly
all MCUs, except the 1180.
## [0.1.7] 2025-06-14
Introduce `RuntimeBuilder::in_flash` for creating images that can be launched
by your own software, instead of NXP's boot ROM.
Place sections starting with `.xip` into the same load region of `.text`.
Unlike `.text`, the contents in `.xip` will not be relocated.
Four byte align both the `.xip` and `.text` sections for more predictable
behaviors across linkers.
## [0.1.6] 2025-03-01
Add new MCU targets:
- imxrt1040
- imxrt1160
Document workaround for registering exception handlers.
## [0.1.5] 2024-10-26
Add initial support for RT1180.
## [0.1.4] 2024-04-05
Add configurations to `RuntimeBuilder`:
- `stack_size_env_override`
- `heap_size_env_override`
Use these methods to define environment variables that can override the
stack / heap sizes.
## [0.1.3] 2023-10-01
Ensure that the runtime supports the GNU linker, `ld`.
## [0.1.2] 2023-09-08
Add section for device configuration data (DCD) in linker script. Users
can place their DCD in a section called `.dcd`. Consider using imxrt-dcd
as a convenient way to define a DCD.
## [0.1.1] 2023-02-14
Update to cortex-m-rt 0.7.3 to avoid certain miscompilation opportunities.
For more information, see the [cortex-m-rt advisory][cmrt-0.7.3].
[cmrt-0.7.3]: https://github.com/rust-embedded/cortex-m/discussions/469
Note that imxrt-rt 0.1.0 will no longer build. If you observe this error,
ensure that your build uses this imxrt-rt release.
## [0.1.0] 2022-12-02
First release. `imxrt-rt` provides a build-time API that defines a memory map,
as well as a runtime library that configures i.MX RT 10xx and 11xx processors.
