| 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. |
