3 years ago Similar situation here: I do Lora with interrupt-receive. in the main loop i update a oled display. when i do not use a delay (to reproduce error) i get this stacktrace every minute or so when i use a delay it is not often but still happens.

Hello everyone. I am developing an application that uses both the SPI and I2C. Also I am using both the cores. but I am facing an error no matter what I do. I tried to use one core also without any freeRtos but even then it is happening. the error is esp-idf/components/freertos/queue.c:1446 (xQueueGenericReceive)- assert failed!
Now I trace back the address and here is what I got.
another time I got
This is suggesting something(Adafruit ICM20X or stc3100) was going on using i2c and an interrupt happen (handleInterrupt) and the SPI transaction happens and it failed. Now I don't know how to resolve this issue I have tried many things but I couldn't solve it.
this is ISR of a digital pin that is executed every 500usec. I need specific timing which is why I am executing this SPI related code in the ISR. I have tried not to execute this and tried using semaphore, notification to notify from ISR to a separate task that does this calculation but that didn't satisfied the timing it requires. so I am doing this now in ISR.
here is the my task.
This task is running at
core1with stack size 2000 and priority is 1. Another task is running at core1 with priority 2. Both the task uses 500ms delay for blocking and switching between these two.The queue data from ISR is processed on core 0 with a task of priority 8 and is the only task that is being executed on core0. it also uses BLE.
Kindly advise me on how to deal with this situation. I would be very thankful.
