stm32h7: last word written to RAM may get "reverted" on reset

2

STM32H7's ECC RAM behaves funny on reset [(source)](https://www.st.com/resource/en/application_note/dm00623136-error-correction-code-ecc-management-for-internal-memories-protection-on-stm32h7-series-stmicroelectronics.pdf): > The ECC is computed on data word. If a data smaller than word is written in the volatile memory, the modification...

Don't ignore non-existent algorithms in target YAMLs

9

In target yamls, you reference flash algos by name in `/variants/flash_algorithms`. If you specify an algo that doesn't actually exist in `/flash_algorithms`, it is silently ignored instead of erroring. This...

defmt-rtt: Update to critical-section 1.0

2

This is a breaking change, because 1.0 no longer supplies any critical section implementation by default. The user has to opt-in to one instead (for example, by enabling the `critical-section-single-core`...

Support string interning on Windows, macOS/iOS, Linux, Android

26

Currently defmt only works in ELF targets, and requires a custom linker script. Is supporting non-embedded targets in the radar? - Targets that don't use ELF: **Windows, iOS, MacOS** -...

I'm using a [set of macros](https://github.com/embassy-rs/embassy/blob/master/embassy/src/fmt.rs) to forward log calls to `defmt` or `log` based on Cargo features, to make code portable between embedded and std platforms. I can't find...

```rust #[derive(defmt::Format)] struct Foo { bar: [u8; 4], } info!("Arr: {:x}", [10, 11, 12, 13]); info!("Foo: {:x}", Foo { bar: [10, 11, 12, 13] }); ``` This code prints: ```...

Git DEFMT_VERSION doesn't get updated when doing a Git commit.

We want to add some form of first-class double-buffering support, to allow endless streaming of data. ## Example use cases - Streaming samples from ADC - Streaming samples to DAC...
