• Development Kit: [ESP32-DevKitC]

• Kit version (DevKitC): [v1]

• Module or chip used: [ESP32-WROOM-32D]

• IDF version (run git describe --tags to find it): v4.1-dev-58-g02c7c3885

• Build System: [Make|CMake]

• Compiler version (run xtensa-esp32-elf-gcc --version to find it): 8.2.0

• Operating System: [ LINUX]

• Power Supply: [USB]

Problem Description

I had used UART_NUM_2 event type on esp32 before for reading data of less than 250 bytes and works fine. But there is a problem in getting exact data of more than 330 bytes and the board started rebooting again and again after reading data.

Expected Behavior

All the data should be copied and the board should not reboot.

Actual Behavior

Problem in getting exact data of more than 330 bytes and the board started rebooting again and again after reading data.

Steps to reproduce

1. build 2.flash

// It helps if you attach a picture of your setup/wiring here.

Code to reproduce this issue

// the code should be wrapped in the ```cpp tag so that it will be displayed better.
#include "esp_log.h"
#definr BUF_SIZE 1024
