### Board
ESP32-C3-DevKitC-02 and ESP32-C3-DevkitM-1 and LuotOS.com/t/esp32C3…
### Device Description
I have tried 3 different setups for ESP32-C3
For the: ESP32-C3-DevKitC-02 and ESP32-C3-DevkitM-1 I use breadboard, to a USB breakout board.
For LuotOS version, the USB connector is actually connected to pins IO18 and IO19. More details about this board up at: https://m.media-amazon.com/images/I/91S2q9qyLcL.pdf
### Hardware Configuration
Nothing other than mentioned above where IO18 and IO19 connected to USB connector.
### Version
2.0.9
### IDE Name
Arduino IDE 2.1 and and nightly build 20230625
### Operating System
Windows 11
### Flash frequency
80mhz
### PSRAM enabled
yes
### Upload speed
921600
### Description
Using the Arduino IDE 2.x debug facility on the ESP32-C3 does not appear to work. Initially it looks like the debugger starts up. But trying to do anything causes it to hang or crash.
Note: this is related to #8334 by @mjs513 but that issue started off as more of a question or issue on how to setup the JTAG for the ESP32-C3 and programming, and this one has more to do once the JTAG over USB is setup, and it appears like the debugger starts up. You soon find that nothing appears to work.
If you feel like this is a duplicate, feel free to close it as such. Some groups like to group things together and others like each specific thing broken out as a new issue.
### Sketch
Any sketch will do, but current one:
```cpp
#include "Freenove_WS2812_Lib_for_ESP32.h"
#define LEDS_COUNT 1
#define LEDS_PIN 8
#define CHANNEL 0
Freenove_ESP32_WS2812 strip = Freenove_ESP32_WS2812(LEDS_COUNT, LEDS_PIN, CHANNEL, TYPE_GRB);
void setup() {
strip.begin();
strip.setBrightness(20);
}
void loop() {
for (int j = 0; j < 255; j += 2) {
for (int i = 0; i < LEDS_COUNT; i++) {
strip.setLedColorData(i, strip.Wheel((i * 256 / LEDS_COUNT + j) & 255));
}
strip.show();
delay(10);
}
}
```
### Debug Message
Not sure what to include here.
Did include a lot of debug information in the steps to reproduce.
### Other Steps to Reproduce
Build your sketch: Note: I have sketch->Opmtimize for debug turned on:
I have JTAG using USB as the image below shows.
I build and upload the sketch,
I then press the debug button and it looks like the debugger comes up:
The debug console window comes up:
```
Type "show copying" and "show warranty" for details.
This GDB was configured as "--host=x86_64-w64-mingw32 --target=riscv32-esp-elf".
Type "show configuration" for configuration details.
For bug reporting instructions, please see:
.
Find the GDB manual and other documentation resources online at:
.
For help, type "help".
Type "apropos word" to search for commands related to "word".
Warning: 'set target-async', an alias for the command 'set mi-async', is deprecated.
Use 'set mi-async'.
0x40000000 in ?? ()
Program stopped, probably due to a reset and/or halt issued by debugger

The gdb-server data: (removed most as text too long)

```
So I decide to maybe set breakpoint at the strip.show line and click on the left of the 19
The debug window shows the red filled circle, and new messages to the console tab:
```
JTAG tap: esp32c3.cpu tap/device found: 0x00005c25 (mfg: 0x612 (Espressif Systems), part: 0x0005, ver: 0x0)
Reset cause (3) - (Software core reset)
Hardware assisted breakpoint 1 at 0x4200004c: file C:\Users\kurte\Documents\Arduino\Rainbow/Rainbow.ino, line 9.
```
I hit the continue button:
And it looked like maybe the code went to line 9, with a few more lines output to debug console tab:
```
Note: automatically using hardware breakpoints for read-only addresses.

[Switching to Thread 1070463660]
Thread 2 "loopTask" hit Temporary breakpoint 1, setup () at C:\Users\kurte\Documents\Arduino\Rainbow/Rainbow.ino:9

```
Tried hitting continue this time, tried step other times... But nothing worked at this point:
Then looked at the gdb-server tab and it was going nuts with continuous output, which I could only stop it by killing the debugger (hit the stop debug button).
Here is an extract from the end of this debug information:
