Framework to collect and upload crashes


| Supported Targets | ESP32 | ESP32-C3 | ESP32-S2 | ESP32-S3 | | ----------------- | ----- | -------- | -------- | -------- | # ESP-Crash Example (`esp-crash-example`) This example is tied to esp-crash, which can be found at https://esp-crash.wennlund.nu/. It is a free service to monitor and display crashes. ## Using the component Run the following command in your ESP-IDF project to install this component: ```bash idf.py add-dependency "jimmyw/esp-crash" ``` ## Example To run the provided example, create it as follows: ```bash idf.py create-project-from-example "jimmyw/esp-crash:esp-crash-example" ``` Then build as usual: ```bash cd esp-crash-example idf.py build ``` And flash it to the board: ```bash idf.py -p PORT flash monitor coredump_crash coredump_upload ``` ## License This component is provided under Apache 2.0 license, see [LICENSE](LICENSE.md) file for details. ## Contributing Please check [CONTRIBUTING.md](CONTRIBUTING.md) for contribution guidelines. ## How to use esp-crash This example uses a coredump partition, named coredump. The built-in crash-handler will write a crash to this partition if you enable CONFIG_ESP_COREDUMP_ENABLE_TO_FLASH=y in your sdkconfig. To add a coredump partition to your esp-idf partition.csv file, you can use the following example: ``` # Name, Type, SubType, Offset, Size, Flags nvs, data, nvs, 0x9000, 0x5000, phy_init, data, phy, 0xe000, 0x2000, factory, app, factory, 0x10000, 1M, coredump, data, coredump, , 128K, ``` This will create a 64K coredump partition. If you have a lot of tasks, you need to increase the size to fit all data. Before you can see your uploaded crashes, you need to access https://esp-crash.wennlund.nu/ with your GitHub account, and register a new unique PROJECT_NAME. After you have registered it, you can add additional team members who can also examine the crashes. ## ESP-Crash Identifier Using ``` esp_err_t esp_crash_identifier_setup() ``` you can add an identifier to RAM, which will always be included in your crash dump. This identifier is in the format: ``` ESP_CRASH:<PROJECT_NAME>;<PROJECT_VER>;<DEVICE_ID>; ``` Example: ``` ESP_CRASH:esp-crash-example;8e8e8df-5.1;6941729232066; ``` This is critical for our backend to pick up, just make it available to your registered project, and know what build file to match up. ## Uploading coredumps Use ``` esp_err_t upload_coredump(const char *url, const char *filename) ``` to upload the coredump directly from a partition to a server. This will read the flash partition and send it as raw data. Upload your crashes to "https://esp-crash.wennlund.nu/dump" if you like to have a free store for your crashes. ## Downloading coredumps Use ``` esp_err_t esp_crash_webserver_start(httpd_handle_t handle) ``` to register the /crash.dmp webserver endpoint. Curling this address will download the last crash if available. After downloading this crash, you can upload it again to "https://esp-crash.wennlund.nu/dump" if you like. ## Interval crash upload Use ``` esp_err_t esp_crash_upload_timer_init() ``` to enable a 60s interval timer, that will try to find an existing core dump, and upload if possible. On success, the coredump partition will be erased. ## Uploading build files To be able to examine your crashes, you also need to upload the elf binary, with debugging symbols. This can be done with this one-liner: ``` curl "https://esp-crash.wennlund.nu/upload_elf?project_name=esp-crash-example&project_ver=$VERSION" -F file=@build/esp-crash-example.elf ``` Ensure $VERSION matches the same PROJECT_VER in your build. This command can easily be added to your CI system. ### CLI commands ``` coredump_crash Crash the esp32 coredump_erase Erase coredump partition coredump_upload [-e] [url] [filename] Upload core dump to server url Url to send to filename Filename -e, --erase Erase after successful upload ``` ## Example Output ## What's upcoming? Im working on an interactive in browser gdb debug session. Its going to be awsome!
