Description

For last week or so we have been trying to get Debug working using the Arduino IDE 2.x debugger with no luck. On setup is based on attacing a USB cable to pins IO18/19 with gnd to gnd and powering from the USB connector. This is based on the following:
Configure ESP32-C3 built-in JTAG Interface

We also downloaded ESP-tools so we have the correct drivers install as we saw this: Arduino IDE 2.X Debug
however even with the driver installed I am see this for the USB connected to D-/D_

When I went to manually install the driver it did not update so went in and tried a different way and gave me an error that said I needed the x64 driver???

GDB console shows the following error:

Debug: 223 62 semihosting_common.c:107 semihosting_common_init():

  Blink

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

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

#define LED_BUILTIN 8

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second

### I have checked existing issues, online documentation and the Troubleshooting Guide

- [X] I confirm I have checked existing issues, online documentation and Troubleshooting guide.

[KurtE]

@mjs513 - I have the same issue with a different C3 module: https://www.amazon.com/dp/B0BWN14X65

I have also tried hooking it up to an RPI Pico board. running as a CMIS-DAP JTAG using https://github.com/ataradov/free-dap
I have another Pico running the same software that talks to an Arduino MKRZero using swd mode. I believe the ESP32-C3 does not support SWD mode so I hooked it up with 4 signal wires:
RPI pin ESP32_pin
11(SWCLK/TCK) -> GPIO6
12(SWDIO/TMS) -> GPIO4
13 TDI -> GPIO5
14 TDO -> GPIO7

So far they are not talking. It is unclear to me how to configure the IDE to support this?

[me-no-dev]

@mjs513 your configuration is correct. Did you make sure that before starting debug you actually built and uploaded the sketch that you want to debug? This must be done any time you restart the IDE/reopen the sketch. Necessary because some files need to be copied to the sketch folder and ELF to be picked up by GDB. Use only the top 3 buttons of the IDE to compile and start debug.

[me-no-dev]

@KurtE C3 has integrated JTAG. No external hardware or connections are necessary other than the USB port, as @mjs513 explained

[mjs513]

@me-no-dev thanks for getting back to us so fast. The answer to your question is yes I uploaded the sketch first and then hit the debug button on the top of the IDE. As @KurtE said he tried it with a different board than I have as well as trying to use the JTAG connectors.

At this point do not know where to go from here. As you said it should work.

edit: Think whats bothering me is that its not seeing the debug port as a USB/JTAG port.

EDIT2: It might be related to #7295, followed the same procedure to update driver. it shows driver is installed but my x64 machine is not seeing it or not recognizing that the driver is associated the port.

[mjs513]

@me-no-dev and @KurtE
Tried using VSCode just to see if would recognize the port and upload and if failed with the same error. Its not seeing the usb cable attached to pins 18/19 as as seperate device. Only seeing one device on com8. From what I understand I should be seeing 2 com ports but I am not. If I try to install with have disk I am seeing:

[KurtE]

@KurtE C3 has integrated JTAG. No external hardware or connections are necessary other than the USB port, as @mjs513 explained

Understood, but when the USB connection did not works, I thought I would try the other option. LIke what is described in:
https://visualgdb.com/tutorials/esp32/esp32-c3/

Note some of their instructions for using the USB Port version:

Their cable made no sense to me as I believe they are the same pins that hook up to the actual USB connector:

Wondering when the board boots up and I open up the Serial Monitor window, I see a bunch of text messages:
That appear like the keep repeating, with data like:

If this is related with JTAG stuff or potentially some internal debug stuff that is outputting by default?

@KurtE
This is the ESP32-C3 bootloader messages.
Not related to the debugging process.

[mjs513]

Not sure if this pertains to the current issue or not. After some more googling I found this
https://www.esp32.com/viewtopic.php?t=31380

basically it adds the following command arg to opencd:
-c "gdb_memory_map disable"
I would try to add it but not sure where to even give it a try.

Thanks, today I have had some luck at least getting the debugger up. My ESP32-c3 board has external 4mb flash and I need to configure the flash to DIO mode instead of QIO mode.

Now at least the debugger comes up. Not sure what the configuration should be if the ESP32-c3 has internal flash. WIll hopefully find out soon, as other one(s) arrive in a few days.

Note, I don't think it is working overly well, as if you try to step or the like it sort of hangs or restarts...
But at least it comes up.

Wonder if some of these issues are due to differences between Arm Cortex versus risc-v

Arduino 2.0.9 uses IDF 4.4, therefore this fix is already included.

Thanks - need to make sure. But I just received a ESP32-C3 WROOM DevKitC-02 and connected it up and it works out of the box - the second serial port shows as USB Serial that pins 18/19 are connected with the USB cable so it has to be something with the board.

[mjs513]

Just to close the loop I finally tracked down the issue with JTAG not working on this paticular board. Turns out its a hardware issue - pins18/19 are shorted together even though there does not seem to be a solder bridge on my soldering on the header pins. Pulled out my multimeter and tested. Tried it a different board (came in a package of three) and it worked so going to close out this issue.

@me-no-dev @mjs513 - I can start up the debugger on a couple of the different boards, but wondering does any of it actually work?

Once it starts up can you get it to set a breakpoint and have it be hit. And if it is hit, can you continue from this location?
Can you use the step in and step over?

If I try to get the code to continue, the gdb-server panel starts producing lots of debug output. I am running the c3 devkit m...
And nothing beyond the startup appears to work for me.
I am probably missing something obvious. but wondering if any of the stuff works for you?

@KurtE
Just hooked the C3 up again (Espressif WROOM esp32-c3 devkit) and can confirm its doing the same thing for me as well. Yesterday I did not notice it.

I am running the BlinkRGB example with a extra Serial.print right before the endif. I hit continue button and I get

in the GDB window. If I hit it again then the spew starts and goes on endlessly.

Here is the sketch I am using:

void setup() {
  // No need to initialize the RGB LED
  Serial.begin(115200);
}

// the loop function runs over and over again forever
void loop() {
#ifdef RGB_BUILTIN
  digitalWrite(RGB_BUILTIN, HIGH);   // Turn the RGB LED white
  delay(1000);
  digitalWrite(RGB_BUILTIN, LOW);    // Turn the RGB LED off
  delay(1000);

  neopixelWrite(RGB_BUILTIN,RGB_BRIGHTNESS,0,0); // Red
  delay(1000);
  neopixelWrite(RGB_BUILTIN,0,RGB_BRIGHTNESS,0); // Green
  delay(1000);
  neopixelWrite(RGB_BUILTIN,0,0,RGB_BRIGHTNESS); // Blue
  delay(1000);
  neopixelWrite(RGB_BUILTIN,0,0,0); // Off / black
  delay(1000);
  Serial.println("end cycle");
#endif
}

also seems to break in setup at Serial.begin(115200) on the first continue button push and then on the second the infinite loop:

@me-no-dev Can you please help with triage and possibly close this issue? Thanks

[me-no-dev]

@VojtechBartoska we need to investigate all outcomes and provide a good info/tutorial on using JTAG with Arduino. The last message clearly states that the JTAG hit the setup() breakpoint, but I suspect that the interface in the IDE did not update. There are different issues between the plugin versions used in the different IDE versions and also some on our side (openocd/gdb) that we have poked the relevant teams about, but seem unfixed still.

I want to make clear that we are mere users of what Espressif offers as OpenOCD/GDB and what Arduino.cc offers as IDE2+cortex-debug. Our configurations were vetted by the IDF team and should work as best as possible on the current platform. It's the nuances between the chips/architecture/interface that are most important to figure out and document. When using external debugger (as required for ESP32 and ESP32-S2) there are far less issues and debugging works much more as expected. Having the USB-JTAG internal, means that the interface gets restarted with the chip and more.
