WebTemporary memory example. //CREATE TEMPORARY MEMORY BUFFER uint32_t *my_temporary_memory_buffer = malloc (1024 * sizeof (uint32_t)); //Allocate a block of size bytes of memory, returning a pointer to the beginning of the block.

And the result was that the pointer after calling ps_malloc, was NULL. Yesterday, with older version of esp32 core, it was working fine, i also upload this same code with Arduino IDE (using esp32 arduino core version 1.0.4) and with that version it was running fine, ps_malloc was working properly.WebAfter adding the Debian Backports software repo to your software sources, you will need to run the update command. The update command will refresh your software sources and add the packages to the package manager. sudo apt-get update.WebWebThere is a limited amount of DMA-capable memory, and it's not available in one contiguous block, so how you allocate it is important. I need a lot of DMA-capable memory for SmartMatrix Library on the ESP32, you might want to search my repo for "MALLOC_CAP_DMA" to see how I use it as a reference. e.g.Big C Arrays with ESP32 don't fit (compile error) or cause a crash at runtime (filed a bug for that). If I allocate the same memory with malloc, it works, at times, and sometimes it works only if I allocate in setup (i.e. after all globals have been assigned and setup gets run) example: pixelmatix/AnimatedGIFs#26The ESP32-CAM can be a bit tricky to setup, follow this guide. ... days so that the camera cannot malloc enough memory when attempting to take a picture.
