If someone could help me better understand the contents of the core dump, and potentially where I could look next, it would be a huge help. And if there's something obvious I'm doing wrong, please let me know.
My initial interpretation is that the Idle task's stack is being overflowed, but I don't know what would cause that stack to overflow, or how to increase the size of it.
In the course of debugging, I've pinned all of the tasks that I'm running to Core 1, just to eliminate the possibility of the communication between the two cores being a cause. Inside the arduino loop function, I'm calling vTaskDelete(NULL) to immediately stop that task, but the reboot is still occurring. The debug message just prior to the reboot indicates a stack smashing protect error, but I'm not sure what stack it's referring to. I've given all of the tasks that I create an abundance of space for their stacks.
The message I get in my debug window just prior to the reboot is below.
---------------------------------------------------------------------------------------------------
Stack smashing protect failure!
abort() was called at PC 0x400f0cac on core 1
Backtrace: 0x400840b1:0x3ffbf26c |<-CORRUPTED
ELF file SHA256: 20e7f869ec436344
-----------------------------------------------------------------------------------------------------
The crashed task's call stack shows that a panic abort is occurring in esp_crosscore_int_send_yield(). I couldn't find documentation on this function, but from the name, I suspect it has something to do with communication between tasks on separate cores.
As I mentioned, I've pinned all of my tasks to Core 1. But entry 6 refers to core 0.
