[SOLVED] Save core dump to flash and read it after reboot as file.

Hello,
I am trying to achieve the following goal:
When a crash happens, it should save a core dump to flash. After a reboot, I want this core dump to be sent to my server (there saved as file) to analyze it further.

For now, I only want to print the core dump from flash after a reboot to UART, so that I can copy it into a file and run the command

Code: Select all

espcoredump.py --chip esp32 info_corefile -t raw -c C:\core_raw.txt C:\project\project.elf
Is it possible to use the binary output (hex format) in combination with the command above? Is the format raw correct?

I created a simple example for this to try out. https://github.com/ddomnik/coredump_example

This is the output after a core dump:

Code: Select all

Without the fff end this are 10112 bytes. However esp_core_dump_image_get() return 5028 bytes?
And what also seems to be strange, the core dumps first 4 bytes are of size a413. However 5028 to hex results in 13A4, so they are rotated?





The other problem problem currently is, that espcoredump.py does not print anything and closes directly.

Even when I try to set the core dump output mode to UART with decoding directly, the python script gives me the following error (with both, binary and elf format):

Code: Select all

================= CORE DUMP END =================

Re: Save core dump to flash and read it after reboot as file.

So I switched to Ubuntu for further testing. Decoding the coredump automatically and manually (via copying it to file) from UART works here without the "object is not subscriptable" error from above.

Also reading from flash directly works now.

However I am still not able to decode a coredump from the flash that I copied to a file. When running:

Code: Select all

python3 espcoredump.py info_corefile -t b64 -c /home/dom/dump /home/dom/esp/coredump_example/build/coredump_example.elf
Also, -t raw and -t elf does not work. Is there some special formatting done before decoding from flash inside the espcoredump.py ?
Or do I have to base 64 encode that binary data?


Code: Select all

python3 espcoredump.py info_corefile -t b64 -c /home/dom/dump /home/dom/esp/coredump_example/build/coredump_example.elf
espcoredump.py v1.2

I forgot to convert the hex file to binary.

Using

Code: Select all

xxd -r -p <input_file> <output_file>
and then running

Code: Select all

python3 espcoredump.py info_corefile -t raw -c /home/dom/dump.bin /home/dom/esp/coredump_example/build/coredump_example.elf
on Ubuntu did the trick! Notice -t raw

Thank you @leschge for providing the snippet code, it works for me.

I'd like to go further: I want to print the traceback directly from the hardware. Most of the time I'm interested only in the current thread stack:

How can I log this info directly from my ESP32 board without downloading a coredump and using external tools?

Sorry for the late response, I don't think that's possible. The decoding is handled by the idf monitor (python), not by the idf itself. At least that's what I found searching for decoding in the git repos. So you always need to read the coredump partition on the next boot and send it to a server for example.
If you want another way to catch errors you may want to take a look at this: https://github.com/espressif/esp-idf/issues/7681

@AAJAY5 i don't think it's possible. Using fwrite requires multiple system components to be working: C library, VFS, filesystem implementation, RTOS, SPI flash driver. Most of these things will not work in the panic handler, as it is similar to the interrupt handler.
You can store the log buffer in RTC memory instead. This memory will persist after reboot and then you can append it to the file, once the system is running normally.
