defmt is a highly efficient logging framework that targets resource-constrained devices, like microcontrollers

Last update: Jan 2, 2023

Overview

`defmt`

defmt ("de format", short for "deferred formatting") is a highly efficient logging framework that targets resource-constrained devices, like microcontrollers.

For more details about the framework check the book at https://defmt.ferrous-systems.com.

The git version of the defmt book can be viewed at https://defmt-next.ferrous-systems.com/.

Setup

New project

The fastest way to get started with defmt is to use our app-template to set up a new Cortex-M embedded project.

Existing project

To include defmt in your existing project, follow our Application Setup guide.

MSRV

defmt always compiles on the latest stable rust release. This is enforced by our CI building and testing against this version.

It still might work on older rust versions, but this isn't ensured.

defmt ecosystem

The following diagram illustrates the user-facing and internal crates of the defmt framework.

Developer Information

Running Tests

Tests are run using cargo xtask -- although this is simply an alias (defined in .cargo/config.toml) for cargo run --package xtask --.

To see a list of options, see xtask/src/main.rs, or run:

$ cargo xtask help

For example, to run all the tests, run:

$ cargo xtask test-all

You will need qemu-system-arm installed and in your $PATH for some of the tests (e.g. test-snapshot).

Support

defmt is part of the Knurling project, Ferrous Systems' effort at improving tooling used to develop for embedded systems.

defmt crate doesn't compile on macOS

Updated description: defmt 0.1.3 compiles on macOS but the git version (0.2.0) doesn't repro:

$ cargo new --bin hello
$ cd hello
$ cargo add defmt --vers 0.1.3
$ cargo run
$ # ^ doesn't work if you use the git version

When trying to get started to write compile fail tests , running $ cargo test --test ui didn't work for me using a mac. I'd always get this unhelpful error:

LLVM ERROR: Global variable '{"package":"defmt","tag":"defmt_prim","data":"{=i8}","disambiguator":"2773326613612971761"}' has an invalid section specifier '.defmt.prim.{"package":"defmt","tag":"defmt_prim","data":"{=i8}","disambiguator":"2773326613612971761"}': mach-o section specifier requires a segment whose length is between 1 and 16 characters.
error: could not compile `defmt`

Passing more flags like this did help: $ cargo test -p defmt --all-features --test ui

This makes sense when looking at ci.yml

target-side `env_logger`-like env filter
This PR implements an alternative approach to disabling/enabling logging in crates. Currently we use Cargo features. This PR removes the need for those Cargo features and replaces them with the env variable: DEFMT_LOG.

The DEFMT_LOG env var specifies which crates should emit defmt logs and at which level. Its syntax is the same as the syntax used by the env_logger crate.

~~The DEFMT_LOG env var parser currently rejects paths that include modules: so DEFMT_LOG=krate=info is OK, but DEFMT_LOG=krate::module=info is rejected. This is intentional and should let us accept module paths and filter based on modules in the future (as in add module support in a backwards compatible fashion).~~ No longer true, DEFMT_LOG now supports module paths.

One of the main advantages of DEFMT_LOG is that allows filtering logs with module level granularity. The current Cargo features based approach is more coarse grained and only supports enabling / disabling entire crates.

NOTE this is a target side emit filter and orthogonal to the host side display filter proposed in knurling-rs/probe-run#74. Disabling logs with the target filter makes the target program smaller (, maybe also slightly faster) and it reduces the amount of data sent from the target to the host. Disabling logs with the host filter does not change the target program at all not it changes the amount of data transmitted from the target to the host.

Changing the value of the DEFMT_LOG env var causes all crates that transitively depend on the defmt_macros crate to be recompiled.

Example usage:

$ bat src/bin/hello.rs

fn main() -> ! { defmt::info!("hello"); foo::foo(); bar::bar(); app::exit() } mod foo { pub fn foo() { defmt::info!("foo"); } } mod bar { pub fn bar() { defmt::info!("bar"); } }

$ DEFMT_LOG=hello::foo cargo r --bin hello 0 INFO foo └─ hello::foo::foo @ src/bin/hello.rs:16 $ DEFMT_LOG=hello::bar cargo r --bin hello 0 INFO bar └─ hello::bar::bar @ src/bin/hello.rs:22 $ DEFMT_LOG=hello::foo,hello::bar cargo r --bin hello 0 INFO foo └─ hello::foo::foo @ src/bin/hello.rs:16 1 INFO bar └─ hello::bar::bar @ src/bin/hello.rs:22 $ DEFMT_LOG=hello cargo r --bin hello 0 INFO hello └─ hello::__cortex_m_rt_main @ src/bin/hello.rs:8 1 INFO foo └─ hello::foo::foo @ src/bin/hello.rs:16 2 INFO bar └─ hello::bar::bar @ src/bin/hello.rs:22 $ rg '\[features' Cargo.toml || echo no Cargo features no Cargo features

how to test this

as this is not even merged into the main branch and breaking changes (with respect to defmt v0.2.0) have landed into defmt, the whole process is quite involved

install a probe-run that uses the decoder in this branch

$ git clone https://github.com/knurling-rs/probe-run $ cd probe-run $ # change the `#[dependencies]` section $ edit Cargo.toml

colored = "2.0" -defmt-decoder = { version = "=0.2.2", features = ['unstable'] } +defmt-decoder = { git = "https://github.com/knurling-rs/defmt", branch = "env-filter", features = ['unstable'] } difference = "2.0"

$ cargo install --path .

use [patch.crates-io] in Cargo.toml (the one in the root of the workspace) to use the git version of defmt instead of v0.2.x. The app-template already includes this section in its Cargo.toml

[patch.crates-io] defmt = { git = "https://github.com/knurling-rs/defmt", branch = "env-filter" } defmt-rtt = { git = "https://github.com/knurling-rs/defmt", branch = "env-filter" } defmt-test = { git = "https://github.com/knurling-rs/defmt", branch = "env-filter" } panic-probe = { git = "https://github.com/knurling-rs/defmt", branch = "env-filter" }

IMPORTANT use branch = "env-filter" instead of rev = "somehash"

set the PROBE_RUN_IGNORE_VERSION env variable before you run your firmware e.g.

$ PROBE_RUN_IGNORE_VERSION=1 cargo run --bin hello

try setting / changing the value of the DEFMT_LOG env variable!

$ export PROBE_RUN_IGNORE_VERSION=1 $ DEFMT_LOG=hello=trace cargo run --bin hello 0 INFO Hello, world! └─ hello::__cortex_m_rt_main @ src/bin/hello.rs:8

As there's other breaking-change work currently ongoing (#508) I plan to leave this work on hold for now -- but will be answering to feedback! -- and resume it when that's concluded.

Unresolved questions

rename DEFMT_LOG to DEFMT_CAPTURE or DEFMT_TARGET_CAPTURE? if we keep the DEFMT_LOG name, what should we name the env var to be used in knurling-rs/probe-run#74?

Add alternate hint ('#')

Also make formatting match core::fmt.

This changes the current behavior, so some thought should be given before accepting. I expect it will break some tests: I'm not sure how to run them all locally so I will rely on CI to find them.

Closes #491

unwrap alternative?

uwnrap() on a Result is quite convenient, but it's not usable with defmt since it requires the error type to be fmt::Debug, which is not useful to print it with defmt.

A solution could be add a trait defmt::Unwrap (or maybe Dewrap?) and implement it for Result, which does the same as unwrap() but printing the result with defmt.

Code size
I have put together a code size testbench to measure code size. It has 2 test cases, spam logs lots of stuff (based on the qemu test) and smoltcp runs smoltcp's loopback example from latest git master (which has defmt support).

spam | smoltcp | what =================================== 18428 | 60680 | main branch 624 | 49780 | no defmt

spam has 156 log calls and is 18428 bytes (.text size). Commenting the run_test() call in main gives a .text size of 944 bytes. Therefore, defmt's code size is:

Base size (RTT stuff, etc): 944 - 624 = 320 bytes Log call size: (18428-944)/155 = 112.8 bytes/call

112.8 bytes/call sounds about right. As seen here, a simple info!("defmt test {=u32}", x); is already 74 bytes of code, and the spam code does a mix of simple and complex log calls.

And 112.8 bytes avg, or 74 bytes to print a u32 is A LOT.

For comparison, let's check good old C printf:

void foo(int x) { printf("defmt test %d", x); }

compiled with arm-none-eabi-gcc -c printf.c -Os -mthumb:

2: 0001 movs r1, r0 4: 4802 ldr r0, [pc, #8] ; (10 <foo+0x10>) 6: f7ff fffe bl 0 <printf>

This is just 8 bytes of code, or 8+14 = 22 bytes if we count the string.

Defmt is 3.5 times larger than printf when counting the string. And this is a generous comparison: arguably the apples-to-apples comparison is not counting the string, since the string pointer is equivalent to defmt's interned string IDs. In which case defmt is 10 times larger.

I'm aware defmt does much more than printf. It's to be expected a log call printing complex nested structs and enums generates bigger code. However, simple log calls (with no arguments or just a handful of integers) are the vast majority in real-world projects, and code size for these really hurts.

probe-rs loses connection with stm32 if stm performs flash write
defmt version: overlap-fix#0ceade69

I am using stm32g081. In my app first couple of flash pages are allocated to bootloader and configuration. When using defmt and at the same time stm32 tries to write to configuration page, communication with the probe will be lost:

Maybe it is possible to reattach to the target without flashing it again? Currently I run it as cargo rrb um8

Edit:

Unfortunately currently it is impossible: probe-run um8 --chip STM32G081KBUxN --defmt --no-flash

Support for ASCII-safe wire encoding

I'm currently working on a platform which isn't supported by probe-rs yet. I'm also working on that, but as of right now my only way to debug the target is using J-Link's GDB server. The problem with that is that its RTT implementation really doesn't like raw bytes, or to be more specific, interprets them as control commands for itself. For instance, FF followed by anything from 00 to 0F will instruct the client to switch its virtual terminal (another mux mechanism on top of the usual RTT channel) causing subsequent bytes to be routed there instead. This issue previously came up in #558.

I get that it's easy to blame this on the J-Link tools, but I feel like this library could really benefit from an additional encoding to cover such cases. For instance, this point is also brought up in #714:

Often these other tools expect utf-8 encoded data, or don't handle reconnection well, or print data other than the raw bytes to their stdout. Basically, these tools tend to not work well as a source for defmt-print's pipe.

Alternatively, this could be achieved using a custom logger, but that would require a second version of every existing logger (e.g. RTT and UART) and wouldn't be picked up automatically by tools like defmt-print.

As for what this encoding might look like, I'm thinking we could encode the frame content using base64 (or ascii85) and use a space as the end-of-frame indicator.

I'm happy to contribute the implementation but wanted to create this issue first to test the waters.

Using RTIC for mutex instead of critical-section

Do we have an example of using RTIC to handle the mutual-exclusion required for the defmt-rtt transport stream, instead of using critical section?

I have a device with an SPI interface, and I would like the SPI interrupt not be disabled whilst I am writing to the RTT. I promise that (or rather, using RTIC I can prove that) the SPI interrupt routine does not use defmt.

Feature flag to print in a non-deferred format.
I'm using defmt as my logging library. I like the efficiency that it enables. However sometimes, I want to be able to view the data without running a printer on the host machine to decode the data. I know that this is antithetical to the design of defmt, but there are several motivating reasons:

Often, I cannot use probe-rs based tools, which means that I need to rely on other tools to read UART, for example

Often these other tools expect utf-8 encoded data, or don't handle reconnection well, or print data other than the raw bytes to their stdout. Basically these tools tend to not work well as a source for defmt-print's pipe.

Sometimes I cannot even get a stdout for the serial data. This happens for example when I'm debugging my hardware with sigrok and a logic analyzer. defmt is not one of the supported encodings for the serial data, I can really only pick hex, ascii, etc.

Sometimes the binary that corresponds to the firmware is unknown. It would suck to have to tear out all of the logging infrastructure in the app and revert to something like log just to make this fix. Maybe my types don't even support Debug and thats going to require a big refactor! It would be nice to have the comfort of knowing that for sure I'll be able to use defmt and choose at the last minute before I ship my firmware whether the logs will be deferred or not.

For the exclusive purpose of enabling easier debugging in these scenarios, would it be possible to turn off the "deferred" part of defmt via a feature flag?

`defmt-rtt` `0.4` breaks on STM32H7A3ZIT6Q

After trying to upgrade, I encountered an issue with defmt-rtt 0.4, no more messages will show up. I am unsure what the root cause is, and to verify that the cause isn't my code, I have created a minimum reproducible example from the recommended app template. If I set defmt-rtt = "0.4" in the Cargo.toml I no longer get any output, while with defmt-rtt = "0.3" that isn't the case.

This is then executed - like in the README - on a STM32H7A3 Nucleo-144.
