Got it working, thanks for the help.

What tools are you using, and what version?

ESP IDF, v5.5-1-gb66b5448e0-dirty

Application is built using:


idf.py build flash monitor


What operating system?

MacOS, latest version, fully patched.

What development boards, and what chip is on them?

ESP-WROVER-KIT (ESP32-D0WDQ6 (revision ...

Tried this on a few boards, all ESP32 and I get the same results.

So changed to SHA256 as you don't trust CRC32.

Full output:

configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

Yes, I see that in running
What I don't see is any information in the retrieved coredump when running these commands

So the following commands:


parttool.py --port /dev/tty.usbserial-1101 read_partition --partition-name coredump --output coredump.bin
idf.py coredump-info -c coredump.bin


generates the following output:


Executing action: coredump-info ...

No luck, Command:


idf.py coredump-info


Output:


A fatal error occurred: Corrupt data, expected 0x1000 bytes but received 0x18d bytes


And these commands:


parttool.py --port /dev/tty.usbserial-2101 read_partition --partition-name coredump --output coredump.bin


Looks to have worked ...

IDF: 5.5
Board: ESP-WROVER-KIT

I have taken the hello_world and added an assert into the code to trigger a failure. The assertion is triggered and the output seems to suggest that coredump is being created.

I then try to read the coredump and the tool set is not reading the coredump from flash ...

I have run the advanced sample and that works.

Merging the CONFIG entry and the code to print the heap statistics into my app (which works without this code/configuration) causes the issue.

So is this looking like an issue in IDF ?

BTW: Full trace is:
