Espressif ESP32 PSRAM/SPI Flash co-existence test
|
|
###########
|
|
|
|
Overview
|
|
********
|
|
|
|
This code tests SPI Flash and PSRAM content integrity after multithreaded and concurrent accesses to
|
|
a common cache. It does so by allocating a big PSRAM memory chunk and repeatedly filling that region
|
|
with a random generated pattern. At the same time, a whole SPI Flash page is updated with another pattern
|
|
value. By the end of the thread iterations, both PSRAM and SPI Flash have its contents compared against
|
|
expected values to check for integrity.

Building and Running
|
|
********************
|
|
|
|
Make sure you have the ESP32 DevKitC connected over USB port.
|
|
|
|
.. code-block:: console
|
|
west build -b esp32 tests/boards/espressif_esp32/cache_coex
|
|
west flash --esp-device /dev/ttyUSB0
|
|
|
|
Sample Output
|
|
=============
|
|
|
|
To check output of this test, any serial console program can be used (i.e. on Linux picocom, putty, screen, etc).
|
|
This test uses ``minicom`` on the serial port ``/dev/ttyUS0``. The following lines indicate a successful test:
|
|
|
|
.. code-block:: console
