backtrace (of rust code) is incomplete on esp32c6
I'm trying to obtain a backtrace for a simple rust program when it panics.
Code:
fn c() {
panic!("oh no");
}
fn b() {
c();
}
fn a() {
b();
}
fn main() {
a();
}
I'm using the esp32c6 here, together with espflash run --monitor.
I have found that the amount of info I can get from the backtrace varies a lot when using esp-idf-sys compared to when using esp-hal.
rust --version -v:

esp-hal // no_std Case
Based on cargo generate esp-rs/esp-template I have the following setup.
main.rs:
#![no_std]
#![no_main]
use esp32c6_hal::prelude::*;
use esp_backtrace as _;
fn c() {
panic!("oh no");
}
fn b() {
c();
}
fn a() {
b();
}
#[entry]
fn main() -> ! {
a();
loop {};
}

Conclusion / Summary
The output of the esp-idf-version does not contain any of my functions (a,b,c). It does contain main, buried under a lot of noise.
I dont care a lot about the noise, but I would really like to see my functions (a,b,c).
Experiment 1: Add esp_backtrace to get more/alternative output.
New dependencies in Cargo.toml:
esp-backtrace = { version = "0.10.0", features = ["print-jtag-serial", "esp32c6"] }
Modified function c in main.rs:
fn c() {
let bt = esp_backtrace::arch::backtrace();
for a in bt {
if let Some(a) = a {
println!("esp_backtrace: 0x{:x}", a);
}
}
panic!("oh no");
}
Additional output compared to before (raw, without espflash monitor):
esp_backtrace: 0x4200028a
esp_backtrace: 0x4201e1ae
esp_backtrace: 0x42000270
espflash run --monitor enhanced:

at /home/timo/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/std/src/rt.rs:172
This does not really add much value on its own. The functions in question are still missing.
Experiment 2: Add #[inline(never)]
I've annotated my functions a,b,c with #[inline(never)] , the rest is the same as in Experiment 1.
main.rs
#[inline(never)]
fn c() {
let bt = esp_backtrace::arch::backtrace();
for a in bt {
if let Some(a) = a {
println!("esp_backtrace: 0x{:x}", a);
}
}
panic!("oh no");
}
#[inline(never)]
fn b() {
c();
}
#[inline(never)]
fn a() {
b();
}
fn main() {
esp_idf_svc::sys::link_patches();
esp_idf_svc::log::EspLogger::initialize_default();
a();
}

esp_backtrace contains main now, but not a,b,c
panic output contains main, a and b but is still very noisy and not really helpful
Experiment 3: Set RUST_BACKTRACE=1
I've added std::env::set_var("RUST_BACKTRACE", "1"); to main.rs, the rest is the same as in Experiment 2.
main.rs
#[inline(never)]
fn c() {
let bt = esp_backtrace::arch::backtrace();
for a in bt {
if let Some(a) = a {
println!("esp_backtrace: 0x{:x}", a);
}
}
panic!("oh no");
}
#[inline(never)]
fn b() {
c();
}
#[inline(never)]
fn a() {
b();
}
fn main() {
esp_idf_svc::sys::link_patches();
esp_idf_svc::log::EspLogger::initialize_default();
std::env::set_var("RUST_BACKTRACE", "1");
a();
}

Same results as in experiment 2.
Experiment 4: Enable DWARF by setting CONFIG_ESP_SYSTEM_USE_EH_FRAME=y
I've added CONFIG_ESP_SYSTEM_USE_EH_FRAME=y to sdkconfig.defaults, the rest ist the same as in experiment 3.
sdkconfig.defautls
# Rust often needs a bit of an extra main task stack size compared to C (the default is 3K)
CONFIG_ESP_MAIN_TASK_STACK_SIZE=8000
CONFIG_ESP_SYSTEM_PANIC_PRINT_REBOOT=n
CONFIG_ESP_SYSTEM_PANIC_PRINT_HALT=y
CONFIG_ESP_SYSTEM_USE_EH_FRAME=y
Note: this needs "-C", "force-unwind-tables=yes" rustc flags to work properly. Thanks @Vollbrecht

the panic output now contains main, a, b and c, and is much more concise. :+1:
(note: It ends with the error Backtrace ended abruptly: cannot find DWARF information for instruction at address 0xfffffffe)
Conclusion
Coming from esp-hal, I find the backtraces on esp-idf-sys extremely painful to handle. They contain a lot of noise, and unless i enable DWARF generation, they will not contain any of my functions in question or only some of them. Surely there must be a way to get a clear and concise backtrace?
How can we improve the situation?
When printing with esp_backtrace, why dont I see my rust functions a,b and c, when using esp-idf-sys instead of esp-hal. Have my frame pointers suddenly disappeared?
Thank you!
Your original experiment, in the original issue report:
espflash run --monitorenhanced output: contains main, but neither a, b or c and is really verbose
This is because the panic output from ESP IDF contains a stack memory dump, that - unluckily - is not formatted with regular byte-oriented hexdump i.e. 0a 0c 22 34 but with clusters of 4 bytes each where each such cluster looks like (but isn't necessarily) a 32bit value.
My guess is that espflash blindly applies stacktrace decoding on the memory dump, assuming that each such 4-byte cluster is a properly decoded 32 bit word. ~~Which seems not to be the case.~~ Hence the noise.
Experiment 1: Add esp_backtrace to get more/alternative output. Experiment 2: Add #[inline(never)]
esp_backtrace contains main now, but not a,b,c
I don't have explanation for that. That's weird, because from LLVM's POV, the two targets look exactly the same.
Maybe following question: what are your optimization settings? (opt-level)? 0, 1, 2 or 3? It could be, that with opt-level != 0, even if you say "inline(never)", stuff is still sometimes inlined, though then I don't have an explanation why the b symbol then pops up in the stack memory dump below.
UPDATE: Seems you are running with level "z" (optimize for size, but still inline). What happens if you change this to 0?
UPDATE 2: Not clear from the no_std Cargo.toml, but it seems you are running with opt-level 0 (in the absence of anything else specified)? If so, this is not apples-to-apples comparison, and would explain the differences in the output from esp_backtrace
panic output contains main, a and b but is still very noisy and not really helpful
Sure. As per above, espflash crawls though the stack memory and blindly applies decoding to everything which looks like a 32 bit word. Including to stuff which is is definitely not an IP (instruction pointer), but data.
Suggestion for improvement: the noise might get reduced if the decoding is applied by espflash only on 32bit words which start from 0x4000000. If I'm not mistaken, ESP programs start from this address.
Experiment 3: Set RUST_BACKTRACE=1
There IS a difference! :)
Snippet from experiment 2:
thread 'main' panicked at src/main.rs:11:5:
oh no
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
abort() was called at PC 0x4202ac81 on core 0
Snippet from experiment 3:
thread 'main' panicked at src/main.rs:11:5:

stack backtrace:

Where originally it used to say
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
now it says:
stack backtrace:
stack backtrace: is coming from the Rust stack walker in the panic crate. It is "just" that the stack trace generated by the panic crate is completely empty. Well, apparently the thing does not work with riscv frame pointers enabled (unlike esp_backtrace!). It does work with xtensa frame pointers enabled though. Weird. Maybe we need to upstream a patch into it!
espflash crawls though the stack memory and blindly applies decoding to everything which looks like a 32 bit word. Including to stuff which is is definitely not an IP (instruction pointer), but data.
Another idea could be to run GDB (if installed) and actually decode the backtrace based on the stack and the registers, like https://github.com/espressif/esp-idf-panic-decoder/blob/master/esp_idf_panic_decoder/gdb_panic_server.py does.

Aaah, good catch. :tada:
This at least fixes the esp_backtrace case when used in combination with std::panic::set_hook
Experiment 1b
Instead of using
opt-level = "z"
lets use
opt-level = 0
and then invoke esp_backtrace in as a panic hook.
main.rs:
fn c() {
panic!("oh no");
}
fn b() {
c();
}
fn a() {
b();
}
fn main() {
esp_idf_svc::sys::link_patches();
esp_idf_svc::log::EspLogger::initialize_default();
std::panic::set_hook(Box::new(|info| {
println!("panic occurred: {:?}", info);
let bt = esp_backtrace::arch::backtrace();
for a in bt {
if let Some(a) = a {
println!("esp_backtrace: 0x{:x}", a);
}
}
}));
a();
}
espflash now outputs:

Experiment 4: Enable DWARF by setting CONFIG_ESP_SYSTEM_USE_EH_FRAME=y
For me, this works. The output from espflash is still very noisy, because espflash seems to apply IP decoding on everything. So e.g. in Backtrace: 0x40800eba:0x4080f1a0 ... it decodes not just 0x40800eba but also 0x4080f1a0 (what is this?) which is wrong and results in noisiness.
Conclusion Coming from esp-hal, I find the backtraces on esp-idf-sys extremely painful to handle. They contain a lot of noise, and unless i enable DWARF generation, they will not contain any of my functions in question or only some of them. Surely there must be a way to get a clear and concise backtrace?
Let's unpack this a bit for the sake of being precise:
- Situation only an issue with riscv chips, not xtensa (ok, pretty bad as everything new is riscv anyway)
- Noisiness comes from the unfortunate combination of
espflash monitoreagerly applying decoding on everything which looks like a memory address + the raw memory dump generated by ESP IDF on riscv*. Not specific to ESP IDF, oresp-idf-sysper se
How can we improve the situation?
Let's put the "noisiness" problem aside for the moment. Let's look at the three supported stack-walking schemes:
1. DWARF based (solved for me)
- I think this works. Thanks again to @Vollbrecht for
"-C", "force-unwind-tables=yes"
Action item: document this approach better somewhere
2. riscv frame-pointer based
- I think that can be made to work for ~~Rust code~~ LLVM
- I don't think we can make it work for GCC, as I have been unable to force riscv frame pointers with GCC
- I'm not sure what would happen with stack walking if you have a mixed Rust/C stack, where some frames have frame pointers, and others - don't. If this confuses the stack walker, "I think that can be made to work for Rust code" would be an exaggeration for code that calls C and then the C code calls back Rust code
Action item: We can try to upstream the esp_backtrace code in Rust's unwind crate. But only if "it is worth it", i.e. mixed Rust/C stacks can be at least partially decoded (at least the Rust part)
3. GDB decoding of the memory stack frame
- Will "just work" for ESP IDF with default settings
- Needs us to resurrect the project that wrapped the
idf.pytooling (cargo espidf ...) OR - Needs us to enhance
espflashwith what amounts to a port of the Python code that @igrr mentioned above. Seems to me a non-trivial effort
Action item: Work on the first or second option
When printing with esp_backtrace, why dont I see my rust functions a,b and c, when using esp-idf-sys instead of esp-hal. Have my frame pointers suddenly disappeared?
Different optimization settings, as per above?
The noisiness problem
I think we should postpone this for a while, until we figure out whether we need to concentrate on (2) or (3).
Oops. I was a bit too eagerly creating https://github.com/esp-rs/espflash/issues/543, seeing your conclusion here ^^.
Can you take over, and create the remaining issues/tasks based on your action items?

i think for gdb and stuff as long as you are not talking about the gdb-stub over uart rather connecting external gdb server, we already have a working solution with probe-rs. So it think we don't need espflash for that

No it is not gdb-over-uart. It is about (ab)using GDB to do the stack walking for us when presented with (a) The stack memory (3K or so) (b) The registers as they were valid for the stack topmost frame (c) The original ELF file (for DWARF tables & stuff)
Basically, we have to either find a way to run this script and the ESP IDF monitor in general
or
translate the above Python script (and maybe a few accompanying ones) to Rust, and then use from within the espflash monitor code.
And given that the whole stack memory + registers' dump is so ESP IDF specific, perhaps it would be easier and more natural to just find a way to call idf.py monitor with a cargo sub-command like cargo espidf. Especially given that we have the ESP IDF and all its tooling (we can also force the GDB tool to always be auto-installed by esp-idf-sys) in the .embuild directory.
Which brings back the question/trick from some time ago which is that we have to have at least one successful build of esp-idf-sys so that we get as an output from it all build settings, including the location of ESP IDF and its tooling, as utilized by the project. This task was in the context of cargo espidf menuconfig but it is basically the same for the future cargo espidf monitor that we are discussing here.
Oops. I was a bit too eagerly creating esp-rs/espflash#543, seeing your conclusion here ^^.
Can you take over, and create the remaining issues/tasks based on your action items?
I think we can keep it simple and have just this task/issue for now. I would only create a separate task for the documentation of the DWARF "trick" in the Rust ESP book.
