Code: Select all

uint32_t i = 0 ;

ESP_LOGI(TAG,"free size (psram):%d",heap_caps_get_free_size(MALLOC_CAP_SPIRAM));

uint8_t * tbuf = (uint8_t*)heap_caps_malloc( 32*1024 , MALLOC_CAP_SPIRAM | MALLOC_CAP_32BIT );

ESP_LOGI(TAG,"addr[%x]",(uint32_t)tbuf);

ESP_LOGI(TAG,"free size (psram):%d",heap_caps_get_free_size(MALLOC_CAP_SPIRAM));

for(i=0 ; i < 32*1024 ; i++)
{  
   tbuf[i] = 0 ;
}

show_hex(tbuf,256);
