Esp32 debugging

1

I’m a newbie using the esp32 board(esp-wrover-kit) for the first time, and I have the following questions;

  1. I opened the espidf-arduino-blink project in platformio, and I could see that framework = arduino, espidf was set. Can I use both frameworks?
[env]
platform = espressif32
framework = arduino, espidf
build_flags =
    -D CONFIG_BLINK_GPIO=2
monitor_speed = 115200
  1. When debugging the esp-wrover-kit board (ftdi interface), the following warning message is displayed. How can I modify it?
undefinedC:\Users\JJS\.platformio\packages\toolchain-xtensa-esp32\bin\xtensa-esp32-elf-gdb.exe: warning: Couldn't determine a path for the index cache directory.

  1. Debugging with ftdi is too slow, is there any way to speed it up?
[env:esp-wrover-kit]
platform = espressif32
board = esp-wrover-kit
framework = arduino
  1. What is the default debugger for platformio? openocd?

Yes per platform-espressif32/examples/espidf-arduino-blink at develop · platformio/platform-espressif32 · GitHub and multiple posts in this forum.

Non-critical warning, already tracked.

For Platform-espressif32, it is openocd. Other platforms and microcontrollers can use other GDB servers, like pyocd, JLinkGDBServer, avarice, …
