StoreProhibited error when equating two pointers
Posted: Fri Apr 01, 2022 2:07 am
Hello, I am using the ESP-WROOM-32 with the latest version of ESP-IDF and have run into an error. I am trying to set a double pointer in a struct equal to another double pointer. My code works fine until it encounters this line of code (it works if it is commented out) where it will cause the core to panic and say StoreProhibited.
Here is the error message:
Here is the line that causes the error:
To my understanding, StoreProhibited normally means that you are trying to write to non-existent memory, however, I have allocated memory for both of these pointers in a separate task that definitely runs before the line of code in question.
Here is the struct to show the double pointer:
This could very well be just a misunderstanding of how pointers work, but any help would be appreciated.
Here is the error message:
