Device Description

Nothing attached.

Hardware Configuration

Bare board. Nothing attached.

Version

v3.3.2

Type

Bug

IDE Name

VSCode with pioarduino

Operating System

macOS 15.7

Flash frequency

80 MHz

PSRAM enabled

yes

Upload speed

115200

Description

When a platformio.ini file enables the esp32_exception_decoder:

monitor_filters = 
    esp32_exception_decoder

and the serial output sends a variable that starts with 0x, the exception decoder will output a line not related to an error.

For example:

[   138][I][esp32-hal-periman.c:141] perimanSetPinBus(): Pin 19 already has type USB_DM (45) with bus 0x3fc976bc
  #0  0x3fc976bc in ?? at /Users/user/.platformio/packages/framework-arduinoespressif32/cores/esp32/HWCDC.cpp:619

[   138][I][esp32-hal-periman.c:141] perimanSetPinBus(): Pin 20 already has type USB_DP (46) with bus 0x3fc976bc
  #0  0x3fc976bc in ?? at /Users/user/.platformio/packages/framework-arduinoespressif32/cores/esp32/HWCDC.cpp:619

the lines that start with #0 are not valid.

The bug is seen when printing pointers (%p).

If you format the pointer as something like addr_%08x the #0 lines do not appear. But note, if addr_ is replaced with 0x the bug is still triggered.

Sketch

Any sketch.
But in the `platformio.ini` file, set `-DCORE_DEBUG_LEVEL=` to 4 or 5.

Debug Message

See description above.

Other Steps to Reproduce

If you comment out:

monitor_filters = 
    esp32_exception_decoder

in the platformio.ini, the bug does not show.

@Xylopyrographer Not an Arduino core issue. The problem is in the used exception decoder in pioarduino. The exception decoder from pioarduino is not the same as the used in ArduinoIDE.

[Jason2866]

What would be the correct behaviour? Ignore output which starts with #0?
The regex responsible for is here https://github.com/pioarduino/platform-espressif32/blob/2ca7267f1864df55346aa44ba591fef3f6f24710/monitor/filter_exception_decoder.py#L34-L36

@Xylopyrographer Please try branch https://github.com/pioarduino/platform-espressif32/tree/fix_exec_decoder if the changes in exception decoder fixes the issue

A more intrusive change which takes care of context in this branch
https://github.com/pioarduino/platform-espressif32/tree/exec_dec_context

@Jason2866 : Confirmation on trying the fix_exec_decoder branch.

With this as the platformio.ini file:

[env:monitorfix]
board = ws_esp32_s3_matrix
platform = https://github.com/pioarduino/platform-espressif32/tree/fix_exec_decoder
framework = arduino
build_type = debug
board_upload.flash_size = 4MB
board_build.arduino.memory_type = qio_qspi
board_build.flash_mode = qio
board_build.f_flash = 80000000L
build_flags =
    -DBOARD_HAS_PSRAM
    -DARDUINO_USB_MODE=1
    -DARDUINO_USB_CDC_ON_BOOT=1
    -DCORE_DEBUG_LEVEL=5
monitor_speed = 115200
monitor_filters = 
    esp32_exception_decoder
upload_protocol = esptool

pio throws the following error:

Or do you mean overwrite the existing filter_exception_decoder.py in /Users/user/.platformio/platforms/<platform_diretory>/monitor/filter_exception_decoder.py with the revised one?

[Jason2866]

@Xylopyrographer Wrong syntax. Correct is

platform = https://github.com/pioarduino/platform-espressif32.git#fix_exec_decoder

or overwrite the file in your existing is working too

[Xylopyrographer]

@Jason2866 Confirming the %p format specifier no longer causes the exception decoder to output spurious lines 👍.
