i.MX RT Runtime Support https://git.mciantyre.dev/imxrt-rt/atom?h=main 2025-11-26T15:49:04+00:00 2025-11-26T15:49:04+00:00 Ian McIntyre me@mciantyre.dev 2025-11-26T15:17:14+00:00 urn:sha1:8b0d5278b0de5254a242f8a356f061949a896161 The vector tables exported by imxrt-ral are smaller than the default cortex-m-rt vector table. The tests fail once we enable the rt / device features. With this change, we expect the MCU-dependent vector table sizes. 2025-11-11T13:24:38+00:00 Ian McIntyre ianpmcintyre@gmail.com 2023-03-13T10:50:57+00:00 urn:sha1:6f5633761528e484e8d0963c7ac59403f7210093 Just a proof-of-concept. The new inspect_elf test seems to show that we're building the correct image. We need another commit in order to help the program run in FlexRAM. 2025-09-16T11:47:23+00:00 Ian McIntyre me@mciantyre.dev 2025-06-14T14:16:12+00:00 urn:sha1:9728ac5305cfe259115858f0bc49985a0ad7cec4 I'm considering this a breaking change. I'll try to introduce new sections that rely on the user's `unsafe` keyword for linker placement. Rust 2024 has different opinions on format, and clippy has new thoughts. Let's adopt them. 2025-03-22T00:04:24+00:00 Sherif A Abdou sherif_abdou@outlook.com 2025-02-03T15:22:32+00:00 urn:sha1:b319d62052d6b553b135837ff8c35ee0c8d475bf Applications linked through this builder can be placed in a flash reservation. You'll need some other software to launch these programs, since they lack the boot header required by the NXP boot ROM. 2024-10-16T12:51:14+00:00 Ian McIntyre me@mciantyre.dev 2024-10-16T12:51:03+00:00 urn:sha1:cb3af5ba736443adbf3dbf305f7a95aa23f3d26b 2024-04-03T13:52:56+00:00 Ian McIntyre ianpmcintyre@gmail.com 2024-02-22T21:55:34+00:00 urn:sha1:feca35c7c12b3ad2fb8cd5c4e48003da2b283b8b If you define a runtime, you can call `stack_size_env_override` to define an optional environment variable checked by the runtime builder. Same goes for the heap. A user can set these environment variables to override the runtime's stack / heap size. You can use this package's examples to try it out; see the updated build script. There's no default environment variable for either memory region. The package that defines the runtime needs to opt-in to this feature. 2023-09-08T23:18:34+00:00 summivox summivox@gmail.com 2023-08-21T06:13:59+00:00 urn:sha1:c6d3bcfb11800c58339037be58fa9935f816f1bb Users can define their device configuration data (DCD), and place the data in the .dcd section. If the .dcd section has content, the entry in the IVT points at the user's DCD. This plays well with imxrt-dcd. 2022-12-02T01:21:05+00:00 Ian McIntyre ianpmcintyre@gmail.com 2022-08-02T10:21:12+00:00 urn:sha1:c7a9b9f3d4b9e71303c7b988d2bd916c2e4df9bc
