ESP32 DEVKIT v1 with C1001

I tyred the esp32 devkit v1 with C1001 ,  i has correct the code with #include "DFRobot_HumanDetection.h"

#define RXD1 16  // RX2

#define TXD1 17  // TX2

DFRobot_HumanDetection hu(&Serial1);

void setup() {

  Serial.begin(115200);  // Per monitor seriale

  Serial1.begin(115200, SERIAL_8N1, RXD1, TXD1);  // Seconda seriale su GPIO16 (RX), GPIO17 (TX)

but the output serial is :

mode:DIO, clock div:1

load:0x3fff0030,len:4744

load:0x40078000,len:15672

load:0x40080400,len:3152
