This follows a similar approach as UART core dump handling in
idf_monitor. Panic handler message is detected in the output,
collected into a file, and the file is passed to the decoding script.
In this case, the decoding script acts as a tiny GDB server, so we
can ask GDB to perform the backtrace.
* add toolchain file
* add linux to preview targets
* add stub for dfu number in cmake
* excluded unity runner per default
* Added esp_attr.h and esp_partition.h linux stubs
* component.cmake check list for emptyness
* added switch for linux in unity cmake file
* Added Linux host example app
When idf.py gdb starts, it expects openocd was started in the background
and creates a thread to watch for openocd errors. when gdb target exits,
the debug_ext.py aims to cleanup all threads and processes, but fails
with traceback if openocd-watch thread not available, which could happen
if openocd started separately.
Can still be enabled by passing --cmake-warn-uninitialized on the command line
Prevents CMake warnings printed by default if IDF_PATH is underneath the CMake
project directory.
The reason for this is that CMake --warn-uninitialized only enables checks
inside the project directory (ie top-level CMakeLists.txt directory and
subdirectories), it doesn't enable for files included from other directories.
(The only way to enable warnings in other directories is to pass
--check-system-dirs and this looks like it's only useful for CMake's own
developers as it prints a lot of warnings from inside CMake otherwise - see
https://gitlab.kitware.com/cmake/cmake/-/issues/19645 )
Plan to follow up with a later commit to clean up most of the warnings (which
aren't problems for CMake execution), but we'll also disable this option by
default to avoid this unexpected triggering of IDF warnings.
Support for execution of asynchronous target, such as openocd, which
by default runs in the background, but if it's the only target idf.py
outputs the openocd in the console waiting for termination by user.
Supports also blocking commands gdb and gdbtui to start a debugging
session in an active console.
Supports running gdbgui running a UI debugging session in a browser
window, using the active console for other commands, such as openocd
or monitor.
Supports combining the debug targets in one action list, such as
idf.py openocd gdbgui monitor
This adds detection of UART core dumps to IDF monitor. By default,
core dumps are not printed to the console, but are processed by
espcoredump.py using 'info_corefile' command. The result is printed
to stdout.
This feature can be disabled in menuconfig.
In the future this can be extended to allow running espcoredump.py
with 'dbg_corefile' argument, which is similar to the current GDB Stub
behavior.
Related to IDF-52.
This solves the issue that target is changed to the default one after
idf.py fullclean.
Also allow setting the default target using sdkconfig.defaults, e.g.
CONFIG_IDF_TARGET="esp32s2"
Closes IDF-1040
