This 29 | crate will compile on 1.30-beta and on stable 1.30 when they are released. 30 | 31 | ## [v0.4.0] - 2018-09-03 32 | 33 | ### Changed 34 | 35 | - This crate no longer depends on `arm-none-eabi-gcc`. 36 | 37 | - [breaking-change] Move from the `panic_implementation` attribute to the 38 | `panic_handler` attribute, which will be stabilized. 39 | 40 | ## [v0.3.0] - 2018-06-04 41 | 42 | ### Changed 43 | 44 | - [breaking-change] moved from the, now removed, `panic_fmt` lang item to the 45 | `#[panic_implementation]` attribute. 46 | 47 | ## [v0.2.0] - 2018-05-11 48 | 49 | ### Changed 50 | 51 | - [breaking-change] made inline assembly (`asm!`) opt-in via the `"inline-asm"` feature. This is a 52 | breaking change because this crate now requires `arm-none-eabi-gcc` to be installed to build 53 | without the `"inline-asm"` feature, which is the default. 54 | 55 | ## v0.1.0 - 2018-04-09 56 | 57 | Initial release 58 | 59 | [Unreleased]: https://github.com/rust-embedded/panic-semihosting/compare/v0.5.3...HEAD 60 | [v0.5.3]: https://github.com/rust-embedded/panic-semihosting/compare/v0.5.2...v0.5.3 61 | [v0.5.2]: https://github.com/rust-embedded/panic-semihosting/compare/v0.5.1...v0.5.2 62 | [v0.5.1]: https://github.com/rust-embedded/panic-semihosting/compare/v0.5.0...v0.5.1 63 | [v0.5.0]: https://github.com/rust-embedded/panic-semihosting/compare/v0.4.0...v0.5.0 64 | [v0.4.0]: https://github.com/rust-embedded/panic-semihosting/compare/v0.3.0...v0.4.0 65 | [v0.3.0]: https://github.com/rust-embedded/panic-semihosting/compare/v0.2.0...v0.3.0 66 | [v0.2.0]: https://github.com/rust-embedded/panic-semihosting/compare/v0.1.0...v0.2.0 67 | -------------------------------------------------------------------------------- /CODE_OF_CONDUCT.md: -------------------------------------------------------------------------------- 1 | # The Rust Code of Conduct 2 | 3 | ## Conduct 4 | 5 | **Contact**: [Cortex-M team](https://github.com/rust-embedded/wg#the-cortex-m-team) 6 | 7 | * We are committed to providing a friendly, safe and welcoming environment for all, regardless of level of experience, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, ethnicity, age, religion, nationality, or other similar characteristic. 8 | * On Matrix and IRC, please avoid using overtly sexual nicknames or other nicknames that might detract from a friendly, safe and welcoming environment for all. 9 | * Please be kind and courteous. There's no need to be mean or rude. 10 | * Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer. 11 | * Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, make a fork and see how it works. 12 | * We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behavior. We interpret the term "harassment" as including the definition in the [Citizen Code of Conduct](http://citizencodeofconduct.org/); if you have any lack of clarity about what might be included in that concept, please read their definition. In particular, we don't tolerate behavior that excludes people in socially marginalized groups. 13 | * Private harassment is also unacceptable. No matter who you are, if you feel you have been or are being harassed or made uncomfortable by a community member, please contact one of the channel ops or any of the [Cortex-M team][team] immediately. Whether you're a regular contributor or a newcomer, we care about making this community a safe place for you and we've got your back. 14 | * Likewise any spamming, trolling, flaming, baiting or other attention-stealing behavior is not welcome. 15 | 16 | ## Moderation 17 | 18 | These are the policies for upholding our community's standards of conduct. 19 | 20 | 1. Remarks that violate the Rust standards of conduct, including hateful, hurtful, oppressive, or exclusionary remarks, are not allowed. (Cursing is allowed, but never targeting another user, and never in a hateful manner.) 21 | 2. Remarks that moderators find inappropriate, whether listed in the code of conduct or not, are also not allowed. 22 | 3. Moderators will first respond to such remarks with a warning. 23 | 4. If the warning is unheeded, the user will be "kicked," i.e., kicked out of the communication channel to cool off. 24 | 5. If the user comes back and continues to make trouble, they will be banned, i.e., indefinitely excluded. 25 | 6. Moderators may choose at their discretion to un-ban the user if it was a first offense and they offer the offended party a genuine apology. 26 | 7. If a moderator bans someone and you think it was unjustified, please take it up with that moderator, or with a different moderator, **in private**. Complaints about bans in-channel are not allowed. 27 | 8. Moderators are held to a higher standard than other community members. If a moderator creates an inappropriate situation, they should expect less leeway than others. 28 | 29 | In the Rust community we strive to go the extra step to look out for each other. Don't just aim to be technically unimpeachable, try to be your best self. In particular, avoid flirting with offensive or sensitive issues, particularly if they're off-topic; this all too often leads to unnecessary fights, hurt feelings, and damaged trust; worse, it can drive people away from the community entirely. 30 | 31 | And if someone takes issue with something you said or did, resist the urge to be defensive. Just stop doing what it was they complained about and apologize. Even if you feel you were misinterpreted or unfairly accused, chances are good there was something you could've communicated better — remember that it's your responsibility to make your fellow Rustaceans comfortable. Everyone wants to get along and we are all here first and foremost because we want to talk about cool technology. You will find that people will be eager to assume good intent and forgive as long as you earn their trust. 32 | 33 | The enforcement policies listed above apply to all official embedded WG venues; including the official Matrix room (#rust-embedded:matrix.org) and linked IRC channels (#rust-embedded on Freenode); GitHub repositories under rust-embedded; and all forums under rust-embedded.org (forum.rust-embedded.org). 34 | 35 | *Adapted from the [Node.js Policy on Trolling](http://blog.izs.me/post/30036893703/policy-on-trolling) as well as the [Contributor Covenant v1.3.0](https://www.contributor-covenant.org/version/1/3/0/).* 36 | 37 | [team]: https://github.com/rust-embedded/wg#the-cortex-m-team 38 | -------------------------------------------------------------------------------- /Cargo.toml: -------------------------------------------------------------------------------- 1 | [package] 2 | authors = [ 3 | "The Cortex-M Team ", 4 | "Jorge Aparicio ", 5 | ] 6 | categories = ["no-std"] 7 | description = "Report panic messages to the host stderr using semihosting" 8 | documentation = "https://docs.rs/panic-semihosting" 9 | keywords = ["panic-handler", "panic-impl", "panic", "semihosting"] 10 | license = "MIT OR Apache-2.0" 11 | name = "panic-semihosting" 12 | repository = "https://github.com/rust-embedded/panic-semihosting" 13 | version = "0.5.3" 14 | 15 | [dependencies] 16 | cortex-m = ">= 0.5.6, < 0.7" 17 | cortex-m-semihosting = "0.3" 18 | 19 | [features] 20 | exit = [] 21 | inline-asm = ["cortex-m-semihosting/inline-asm", "cortex-m/inline-asm"] 22 | jlink-quirks = ["cortex-m-semihosting/jlink-quirks"] 23 | -------------------------------------------------------------------------------- /LICENSE-APACHE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.

Report panic messages to the host stderr using semihosting 2 | //! 3 | //! This crate contains an implementation of `panic_fmt` that logs panic messages to the host stderr 4 | //! using [`cortex-m-semihosting`]. Before logging the message the panic handler disables (masks) 5 | //! the device specific interrupts. After logging the message the panic handler trigger a breakpoint 6 | //! and then goes into an infinite loop. 7 | //! 8 | //! Currently, this crate only supports the ARM Cortex-M architecture. 9 | //! 10 | //! [`cortex-m-semihosting`]: https://crates.io/crates/cortex-m-semihosting 11 | //! 12 | //! # Usage 13 | //! 14 | //! ``` ignore 15 | //! #![no_std] 16 | //! 17 | //! extern crate panic_semihosting; 18 | //! 19 | //! fn main() { 20 | //! panic!("FOO") 21 | //! } 22 | //! ``` 23 | //! 24 | //! ``` text 25 | //!

(..) 36 | //! panicked at 'FOO', src/main.rs:6:5 37 | //! ``` 38 | //! 39 | //! # Optional features 40 | //! 41 | //! ## `exit` 42 | //! 43 | //! When this feature is enabled the panic handler performs an exit semihosting call after logging 44 | //! the panic message. This is useful when emulating the program on QEMU as it causes the QEMU 45 | //! process to exit with a non-zero exit code; thus it can be used to implement Cortex-M tests that 46 | //! run on the host. 47 | //! 48 | //! We discourage using this feature when the program will run on hardware as the exit call can 49 | //! leave the hardware debugger in an inconsistent state. 50 | //! 51 | //! ## `inline-asm` 52 | //! 53 | //! When this feature is enabled semihosting is implemented using inline assembly (`asm!`) and 54 | //! compiling this crate requires nightly. 55 | //! 56 | //! When this feature is disabled semihosting is implemented using FFI calls into an external 57 | //! assembly file and compiling this crate works on stable and beta. 58 | 59 | #![deny(missing_docs)] 60 | #![deny(warnings)] 61 | #![no_std] 62 | 63 | extern crate cortex_m; 64 | extern crate cortex_m_semihosting as sh; 65 | 66 | use core::fmt::Write; 67 | use core::panic::PanicInfo; 68 | 69 | #[cfg(not(feature = "exit"))] 70 | use cortex_m::asm; 71 | use cortex_m::interrupt; 72 | #[cfg(feature = "exit")] 73 | use sh::debug::{self, EXIT_FAILURE}; 74 | use sh::hio; 75 | 76 | #[panic_handler] 77 | fn panic(info: &PanicInfo) -> ! { 78 | interrupt::disable(); 79 | 80 | if let Ok(mut hstdout) = hio::hstdout() { 81 | writeln!(hstdout, "{}", info).ok(); 82 | } 83 | 84 | match () { 85 | // Exit the QEMU process 86 | #[cfg(feature = "exit")] 87 | () => debug::exit(EXIT_FAILURE), 88 | // OK to fire a breakpoint here because we know the microcontroller is connected to a 89 | // debugger 90 | #[cfg(not(feature = "exit"))] 91 | () => asm::bkpt(), 92 | } 93 | 94 | loop {} 95 | } 96 | -------------------------------------------------------------------------------- /triagebot.toml: -------------------------------------------------------------------------------- 1 | [assign] 2 | --------------------------------------------------------------------------------
