Backtrace decoder for ESP32 #105

me21 · 2018-07-03T12:01:29Z

There is a backtrace decoder for ESP32 which is installed in Arduino IDE: https://github.com/me-no-dev/EspExceptionDecoder

And another CLI backtrace decoder written in Python: https://github.com/janLo/EspArduinoExceptionDecoder

It would be nice to use it from Platformio IDE somehow. Serial port monitor is already there, it should be possible to copy&paste the backtrace.

KrrishnaShah · 2018-08-10T09:57:43Z

is there any way to back-trace in ESP-IDF

yaqwsx · 2018-10-14T11:21:36Z

idf_monitor.py in ESP-IDF provides this feature. It scans the serial monitor for addresses a translates them with addr2line. The functionality should be only few lines of code, however:

platformIO does not ship addr2line in the espressif32 package
the serial monitor is not per-platform (mistake me if I am wrong).

I would greatly appreciate this functionality!

yaqwsx · 2018-11-16T19:21:35Z

I briefly looked at the implementation of monitor in PlatformIO. It uses miniterm from PySerial, therefore, it is not easy to extend it by post-processing of the output unless we change PySerial or PlatformIO ships its own monitor.

vallettea · 2019-03-15T16:23:18Z

would also be interested

baggior · 2019-03-15T17:00:46Z

me too

gaelj · 2019-10-28T18:52:01Z

2 years later and this issue is still open... Oh well I guess I wiill have to keep on using the horrible Arduino IDE to debug my ESP32 Guru Meditations.

pierreverbakel · 2019-11-05T22:23:47Z

It keeps amazing me how the Arduino IDE keeps ahead on PlatformIO on some vital points, like this one. I do edit en Visual Code editor with PlatformIO Plugin, try to compile and run in PlatformIO, but then revert to Arduino IDE to understand those crashes. So one could call this IIDDEE-Platform development. Almost like Turbo, but really it feels like using the bird in the Flintstones putting its beak on the rock-record since I know it will do the job... It feels backward indeed ...

louislewis2 · 2019-11-10T22:13:10Z

Guys, again this is ridiculous that such an important feature is simply left untouched.

yaqwsx · 2019-11-10T22:16:07Z

It is, but it would require a significant change to the PIO Serial (e.g. hack the MiniTerm or implement a custom one), so I understand it can take a while to implement.

However, I don't understand why there is no reaction from the PIO maintainers for over a year...

louislewis2 · 2019-11-10T22:32:05Z

I would honestly settle for a copy and paste solution, even that initially would be useful.

pfeerick · 2019-11-14T01:52:46Z

Try janLo/EspArduinoExceptionDecoder... (actually, the me21 fork is supposed to be better for ESP32) if you copy the stacktrace to a file as suggested in the readme, and then run decoder.py from the PIO command line, it should 'just work'. Plus, since it is python based, it should work anywhere PlatformIO does.

I have used luffykesh/EspExceptionDecoder-CLI in the past, but it needs java.

yaqwsx · 2019-11-15T08:40:42Z

Since PlatformIO currently uses Python3, it should be possible to use contextlib.redirect_stdout around the call of miniterm in the PlatformIO core. Then a custom file-like object could do the translation. However, this requires a change to the platform API - it has to be able to provide a custom post-processor. Who should I contact with such a request/consultation?

rohansingh · 2020-01-10T15:50:24Z

It's super-annoying but here's what I use as a workaround:

~/.platformio/packages/toolchain-xtensa32/bin/xtensa-esp32-elf-addr2line \
  -pfiaC \
  -e .pio/build/$ENV/$PROJECT.elf \
  $ADDRESS

Replace $ENV, $PROJECT, and $ADDRESS with appropriate values.

g01d10x · 2020-02-26T07:44:39Z

I personally, and suspect many others would also be very interested in having this added to PlatformIO :D thanks for the great work so far !!

ivankravets · 2020-03-13T10:48:25Z

Thanks to @Tasssadar 's great contribution this issue has been finally resolved! We need some feedback/testing before making the final release of PlatformIO Core 4.3 and this dev-platform. Please re-test:

Open PlatformIO IDE Terminal and run pio upgrade --dev.
Use the upstream version of this dev-platform. See docs https://docs.platformio.org/en/latest/platforms/espressif32.html#upstream
Run pio update.

See documentation https://docs.platformio.org/en/latest/core/userguide/device/cmd_monitor.html#filters

LeedanJohnson · 2020-03-17T23:55:05Z

This works a treat when the upstream dev-platform doesn't break things. On a small demo script, everything went off without a hitch, but when compiling and flashing a larger project (that works fine on the stable platform) something goes wrong. I get a bootloop with garbage coming over the serial line.

valeros · 2020-03-18T08:36:43Z

Hi @LeedanJohnson ! The upstream should work as well, could you please provide more details or even open a new issue?

LeedanJohnson · 2020-03-18T18:42:59Z

EDIT

I tried to replicate the issue after writing the below, so that I could give more details and context, but it worked now. Perhaps there was something I had configured incorrectly. If the issue manifests again, I will make another reply to the thread. Thanks!

Initial Comment

I'd love to supply more details here, but I really don't know what details to provide.
While I have "platform = espressif32" in my platformio.ini file, my full project compiles and runs without a problem (Except for an exception occasionally getting thrown that I'm trying to track down).

If I change that to 'platform = https://github.com/platformio/platform-espressif32.git', the project still compiles and will upload, but will bootloop and spit garbage over the serial line.

Interestingly enough, if I purposefully introduce an exception early on in the program, the same project will start up and run as intended (hitting the exception, and dumping the registers before restarting).

LeedanJohnson · 2020-03-18T19:14:43Z

The issue is back again, with the same behaviour, although I'm not getting the garbled text over serial now. The following is what comes over serial. The second type of boot loops forever.

@LeedanJohnson What framework/board do you use?

LeedanJohnson · 2020-03-18T19:56:50Z

I think this will answer those questions, if not let me know.

Rebooting...

Any ideas?

ivankravets · 2021-06-09T15:35:51Z

pio device monitor -f esp32_exception_decoder. See https://docs.platformio.org/en/latest/core/userguide/device/cmd_monitor.html#filters

wezzix · 2021-10-17T16:57:46Z

TL; DR, Basically just add one line to your platform.ini

[env:your_device]
monitor_filters = esp32_exception_decoder

Wouldn't it be fantastic if this could somehow be the default...

ivankravets · 2021-11-09T12:29:28Z

@tablatronix what is your macOS version? Try to remove ~/.platformio/python3 and ~/.platformio/penv folders, restart VSCode.

tablatronix · 2021-11-09T14:13:59Z

I am not using vscode, cli, but I will poke around a bit in python

ivankravets · 2021-11-09T14:24:38Z

You don't need VSCode, just remove those folders and use installer script https://docs.platformio.org/en/latest/core/installation.html#super-quick-mac-linux.

It seems you installed PlatformIO Core globally where there is an outdated pyserial package.

egnor · 2022-06-30T18:42:07Z

As a breadcrumb for others, if you're adding the filter and it's not doing anything, make sure you have build_type = debug in your platformio.ini (#393)

platformio/platform-espressif32#105 (comment)

See [comment][1]. Do not forget to build in debug-mode. For example in PlatformIO IDE, select as project task 'Advanced' → 'Pre-Debug'. See also [here][2]. To decode backtraces from the Wokwi serial monitor, one can use [this python script][3].
