FreeRTOS on Core1: Guru Meditation Error of type LoadProhibited occurred on core 1. Exception was unhandled.

[Staubgeborener]

I want to run this script here. Basically its initialize the sd card in 1 line mode, enable wifi and create a second task on core 1 to handle the rungbuffer.

But when i call this, i'll get

Code: Select all

I (2588) wifi: mode : null
I (3388) Hinweis: Core 1 for time intensive operation active!
I (3388) wifi: ic_enable_sniffer

This issue happens since i implement sdmmc. But i don't know why? I see in the terminal, that sd card is initialized and wifi is enabled. Also i get from core 1 a message, that the task is activated but (see: Core 1 for time intensive operation active!).

I tested two ESP32s. Both with the same error, so it has something to do with this (weird) source code. What could it be?
For everyone who wants to try this: You don't need all those periphals (except sd card in 1 line mode). As soon you type 'make monitor' the script will start initializing.

You can't vRingbufferReturnItem until you are done using it

[Staubgeborener]

I put vRingbufferReturnItem now in line 175 (update gist), but issue is still the same. I think thats the wrong place...?

[WiFive]

There's basically no error checking. Suggest you study up on coding practices.

LoadProhibited usually means you have an invalid pointer, at least that is what I've learned from my own code.
