ESP32 S2 PSRAM
Posted: Tue Jan 10, 2023 6:19 am
Hi!
I'm using LOLIN S2 Mini, it support 2MB PSRAM.
In Arduino IDE, PSRAM is automatically enabled by board.txt file even PSRAM menu does not exist.
But, I could not initialize PSRAM and found any PSRAM area like this. How can I solve this problem?
PSRAM init NG
Total RAM: 240820, Free RAM: 214684
Total PSRAM: 0, Free PSRAM: 0

Code: Select all
#define SERIAL_PRINTF_MAX_BUFF 256
void serialPrintf(const char *fmt, ...) {
char buff[SERIAL_PRINTF_MAX_BUFF];
va_list pargs;
va_start(pargs, fmt);
vsnprintf(buff, SERIAL_PRINTF_MAX_BUFF, fmt, pargs);
va_end(pargs);
Serial.print(buff);
}
void setup() {
Serial.begin(115200);
delay(3000); // for Serial Display
if (psramInit())
serialPrintf("PSRAM init OK\n");
else
serialPrintf("PSRAM init NG\n");
serialPrintf("Total RAM: %d, Free RAM: %d\n", ESP.getHeapSize(), ESP.getFreeHeap());
serialPrintf("Total PSRAM: %d, Free PSRAM: %d\n", ESP.getPsramSize(), ESP.getFreePsram());
