SPI flash boot problem

Hi everyone, I am using ESP32-WROOM-32 to create a healthcare device for a school project. I am working with MAX30102, and I use library "SparkFun MAX3010x Pulse and Proximity Sensor Library" and run example code from the library. Only one example code for measuring SPO2 "Example8_SPO2.ino" is having this problem while the rest of the other example codes work perfectly. Here is what I got from Serial monitor when I run "Example8_SPO2.ino":

Code: Select all

rst:0x8 (TG1WDT_SYS_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:2
load:0x3fff0030,len:1184
load:0x40078000,len:13104
load:0x40080400,len:3036
entry 0x400805e4

This is very weird and strange for me. I have erased the flash several time, unconnected esp32 with MAX30102, and checked for current and power using a multimeter, but everything is fine. How can I solve this problem?
