cannot upload code in ESP32

[Kashyapkoshti]

rst:0x10 (RTCWDT_RTC_RESET),boot:0x1f (SPI_FAST_FLASH_BOOT)
flash read err, 1000
ets_main.c 371

I am getting this error in my esp32 devkit v1
How to solve it?
I am using arduino IDE for programming the esp32

boot:0x1f indicates you have a lot of strapping pins held high. Disconnect any external devices and try again. Do not use pins 6-11.

In that case you may have hardware issue, because from logs, like @lbernstone said, you have 5 bootstrap pins high including GPIO2.

GPIO2 must also be either left unconnected/floating, or driven Low, in order to enter the serial bootloader.
