Merge branch 'feature/esp32_core_dump' into 'master'
esp32 core dump to flash 1. menuconfig option to select where to store core dump: flash, uart or disable 2. Saving of core dump to flash 3. Partition table definitions files with core dump partition 4. Python scripts to support core dump generation from GDB command line See merge request !341pull/240/head

|

* Core dump in flash consists of header and data for every task in the system at the moment of crash.
|
||||
* For flash data integrity control two magic numbers are used at the beginning and the end of core dump.
|
||||
* The structure of core dump data is described below in details.
|
||||
* 1) MAGIC1 and MAGIC2 are special numbers stored at the beginning and the end of core dump.
|
||||
* They are used to control core dump data integrity. Size of every number is 4 bytes.
|
||||
* 2) Core dump starts with header:
|
||||
* 2.1) TOTAL_LEN is total length of core dump data in flash including magic numbers. Size is 4 bytes.
|
||||
* 2.2) TASKS_NUM is the number of tasks for which data are stored. Size is 4 bytes.
|
||||
* 2.3) TCB_SIZE is the size of task's TCB structure. Size is 4 bytes.
|
||||
* 3) Core dump header is followed by the data for every task in the system.
|
||||
* Task data are started with task header:
|
||||
* 3.1) TCB_ADDR is the address of TCB in memory. Size is 4 bytes.
|
||||
* 3.2) STACK_TOP is the top of task's stack (address of the topmost stack item). Size is 4 bytes.
|
||||
* 3.2) STACK_END is the end of task's stack (address from which task's stack starts). Size is 4 bytes.
|
||||
* 4) Task header is followed by TCB data. Size is TCB_SIZE bytes.
|
||||
* 5) Task's stack is placed after TCB data. Size is (STACK_END - STACK_TOP) bytes.

ESP32 Core Dump
|
||||
===============
|
||||
|
||||
Overview
|
||||
--------
|
||||
|
||||
ESP-IDF provides support to generate core dumps on unrecoverable software errors. This useful technique allows post-mortem analysis of software state at the moment of failure.
|
||||
Upon the crash system enters panic state, prints some information and halts or reboots depending configuration. User can choose to generate core dump in order to analyse
|
||||
the reason of failure on PC later on. Core dump contains snapshots of all tasks in the system at the moment of failure. Snapshots include tasks control blocks (TCB) and stacks.
|
||||
So it is possible to find out what task, at what instruction (line of code) and what callstack of that task lead to the crash.
|
||||
ESP-IDF provides special script `espcoredump.py` to help users to retrieve and analyse core dumps. This tool provides two commands for core dumps analysis:
|
||||
|
||||
* info_corefile - prints crashed task's registers, callstack, list of available tasks in the system, memory regions and contents of memory stored in core dump (TCBs and stacks)
|
||||
* dbg_corefile - creates core dump ELF file and runs GDB debug session with this file. User can examine memory, variables and tasks states manually. Note that since not all memory is saved in core dump only values of variables allocated on stack will be meaningfull
|
||||
|
||||
Configuration
|
||||
-------------
|
||||
|
||||
Currently there are three options related to core dump generation which user can choose in configuration menu of the application (`make menuconfig`):
|
||||
|
||||
* Disable core dump generation
|
||||
* Save core dump to flash
|
||||
* Print core dump to UART
|
||||
|
||||
These options can be choosen in Components -> ESP32-specific config -> Core dump destination menu item.
|
||||
|
||||
Save core dump to flash
|
||||
-----------------------
|
||||
|
||||
When this option is selected core dumps are saved to special partition on flash. When using default partition table files which are provided with ESP-IDF it automatically
|
||||
allocates necessary space on flash, But if user wants to use its own layout file together with core dump feature it should define separate partition for core dump
|
||||
as it is shown below::
|
||||
|
||||
# Name, Type, SubType, Offset, Size
|
||||
# Note: if you change the phy_init or app partition offset, make sure to change the offset in Kconfig.projbuild
|
||||
nvs, data, nvs, 0x9000, 0x6000
|
||||
phy_init, data, phy, 0xf000, 0x1000
|
||||
factory, app, factory, 0x10000, 1M
|
||||
coredump, data, coredump,, 64K
|
||||
|
||||
There are no special requrements for partition name. It can be choosen according to the user application needs, but partition type should be 'data' and
|
||||
sub-type should be 'coredump'. Also when choosing partition size note that core dump data structure introduces constant overhead of 20 bytes and per-task overhead of 12 bytes.
|
||||
This overhead does not include size of TCB and stack for every task. So partirion size should be at least 20 + max tasks number x (12 + TCB size + max task stack size) bytes.
|
||||
|
||||
The example of generic command to analyze core dump from flash is: `espcoredump.py -p </path/to/serial/port> info_corefile </path/to/program/elf/file>`
|
||||
or `espcoredump.py -p </path/to/serial/port> dbg_corefile </path/to/program/elf/file>`
|
||||
|
||||
Print core dump to UART
|
||||
-----------------------
|
||||
|
||||
When this option is selected base64-encoded core dumps are printed on UART upon system panic. In this case user should save core dump text body to some file manually and
|
||||
then run the following command: `espcoredump.py -p </path/to/serial/port> info_corefile -t b64 -c </path/to/saved/base64/text> </path/to/program/elf/file>`
|
||||
or `espcoredump.py -p </path/to/serial/port> dbg_corefile -t b64 -c </path/to/saved/base64/text> </path/to/program/elf/file>`
|
||||
|
||||
Base64-encoded body of core dump will be between the following header and footer::
|
||||
|
||||
================= CORE DUMP START =================
|
||||
<body of base64-encoded core dump, save it to file on disk>
|
||||
================= CORE DUMP END ===================
|
||||
|
||||
Running 'espcoredump.py'
|
||||
------------------------------------
|
||||
|
||||
Generic command syntax:
|
||||
|
||||
`espcoredump.py [options] command [args]`
|
||||
|
||||
:Script Options:
|
||||
* --chip,-c {auto,esp32}. Target chip type. Supported values are `auto` and `esp32`.
|
||||
* --port,-p PORT. Serial port device.
|
||||
* --baud,-b BAUD. Serial port baud rate used when flashing/reading.
|
||||
:Commands:
|
||||
* info_corefile. Retrieve core dump and print useful info.
|
||||
* dbg_corefile. Retrieve core dump and start GDB session with it.
|
||||
:Command Arguments:
|
||||
* --gdb,-g GDB. Path to gdb to use for data retrieval.
|
||||
* --core,-c CORE. Path to core dump file to use (if skipped core dump will be read from flash).
|
||||
* --core-format,-t CORE_FORMAT. Specifies that file passed with "-c" is an ELF ("elf"), dumped raw binary ("raw") or base64-encoded ("b64") format.
|
||||
* --off,-o OFF. Ofsset of coredump partition in flash (type "make partition_table" to see it).
|
||||
* --save-core,-s SAVE_CORE. Save core to file. Othwerwise temporary core file will be deleted. Ignored with "-c".
|
||||
* --print-mem,-m Print memory dump. Used only with "info_corefile".
