I ran the following code. #include <SoftwareSerial.h> //SoftwareSerial USB_HOST_SERIAL = SoftwareSerial(2, 3); // RX, TX void setup() { Serial.begin(115200); delay(100); } void loop() {// put your main code here, to run repeatedly: unsigned long int k = 512 * 1024; //unsigned long int k…

Cast it as a long k = (long) 512 * 1024;

The result of 512*1024 becomes 0
