In the following code, I declared an array of size 3585 bytes, it compiles without error but during execution, it constantly reboots my esp32-Wrover-E chip. If I reduce the array size to 3584 bytes, then there is no such issue. Why? Also, if I declare the array of size larger than 3585 bytes outside...
