Configuration

Operating system: Windows 7 (the bug has been seen also on Win 8.1)

PlatformIO Version (platformio --version): PlatformIO, version 3.6.1a5 (upgraded to dev version)

Description of problem

The debugging of the Arduino Framework fails with FTDI Chip and ESP WROVER KIT

Steps to Reproduce

1. Open arduino blinky example with esp wrover kit (see platformio.ini)
2. Configure FTDI Chip as debugger as described in the forum: https://community.platformio.org/t/esp32-pio-unified-debugger/4541/78 (Normally the debugger sould work with ESP-IDF)
3. Put a breakpoint in line 15 pinMode(LED_BUILTIN, OUTPUT);
4. start debug session
5. Put a breakpoint in line 21 digitalWrite(LED_BUILTIN, HIGH);
6. Push F5

Actual Results

Instead of stopping a the breakpoint line 21, it stopps in the ASM code below

If you push start again it never stops, an the led does not blink

Expected Results

It should stops at the line 21

If problems with PlatformIO Build System:

The content of platformio.ini:

[env:esp wrover kit]
platform = espressif32
framework = arduino
board = esp-wrover-kit
monitor_speed = 115200
build_flags =
	; https://docs.espressif.com/projects/esp-idf/en/latest/get-started/get-started-wrover-kit.html#rgb-led
	-D LED_BUILTIN=2
debug_tool = ftdi

Source file to reproduce issue:

/*
 * Blink
 * Turns on an LED on for one second,
 * then off for one second, repeatedly.
 */

#include <Arduino.h>

// Set LED_BUILTIN if it is not defined by Arduino framework
// #define LED_BUILTIN 2

void setup()
{
  // initialize LED digital pin as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop()
{
  // turn the LED on (HIGH is the voltage level)
  digitalWrite(LED_BUILTIN, HIGH);
  // wait for a second
  delay(500);
  // turn the LED off by making the voltage LOW
  digitalWrite(LED_BUILTIN, LOW);
   // wait for a second
  delay(1000);
}
