Espressif ESP32 SPIRAM test¶
This sample allocates memory from internal DRAM and SPIRAM by calling
k_malloc(), frees allocated memory by calling
checks if memory can be allocated again. Capability of allocated memory is
decided by ESP_HEAP_MIN_EXTRAM_THRESHOLD. If size is less than
ESP_HEAP_MIN_EXTRAM_THRESHOLD, memory is allocated from internal DRAM. If
size is greater than ESP_HEAP_MIN_EXTRAM_THRESHOLD, memory is allocated from
The following SoCs are supported by this sample code so far:
Building and Running¶
Make sure you have your board connected over USB port.
west build -b esp32_devkitc_wrover samples/boards/esp32/spiram_test west flash
If using another supported Espressif board, replace the argument in the above command with a proper board name (e.g., esp32s2_saola).
To check output of this sample, run
west espressif monitor or any other serial
console program (e.g., minicom, putty, screen, etc).
This example uses
west espressif monitor, which automatically detects the serial
