Re: PSRAM init failed! - can't get esp32-cam board to work
It might be a defective module. Please also make sure to enable: PSRAM enabled the options menu I have checked it with an ESP-CAM module that I have: void setup() { Serial.begin(115200); delay(250); // Setup WiiMote if (psramInit()) printf("PSRAM init OK\n"); printf("PSRAM size: %d\n", ESP.getFreePs...

Re: PSRAM init failed! - can't get esp32-cam board to work
Hi
Edit this file in the SDK:
esp32-hal-psram.c
Change the following line:
#if CONFIG_SPIRAM_SUPPORT || CONFIG_SPIRAM
to
#if 1
Then just choose the regular ESP32 Dev kit
Use this code to init the pSARM
if (psramInit())
printf("PSRAM init OK\n");
printf("PSRAM size: %d\n", ESP.getFreePsram());

Calling a C function from Assembly
ESP32:
I have an interrupt service routine written in Assembly
I am trying to call a C function and get a double exception error.
Any Idea?
movi a14, intFunc
callx0 a14
extern "C" void IRAM_ATTR intFunc()
{
counter2++;
}
