Hello everyone,
im quite new to ESP-32 development. I tried to debug my board with the esp-prog debugger.
My Board: ESP32 NODEMCU Module WiFi Dev Kit C Development Board with CP2102 – AZ-Delivery
Im using GND(Upper Right), G15, G13, G12, G14
My ESP-PROG: https://www.amazon.de/TOOGOO-ESP-Prog-Programm-Entwicklung-Kompatibel-schwarz/dp/B07V2LBC4Y/ref=sr_1_1?dchild=1&keywords=ESP-Prog+Jtag&qid=1611230967&s=ce-de&sr=1-1
Pins: TMS, TCK, TDO, TDI, GND
Powerconnection via USB.
I am programming with the Arduino Framework but got some bugs lately and wanted to debug it. i Followed the instructions tried it several times but everytime i get the same errors. It seems that the Debugging is working but it does not go to the brakepoints. I used Zadik for the driver like in the tutorial.
This is my Output:
PlatformIO Unified Debugger →
PlatformIO: debug_tool = esp-prog

Uploading to the chip and halting the core looks good. The debugger seems to break in some point in flash or ROM where it doesn’t know the function name.
What’s the platformio.ini? Have you tried setting debug_init_break = tbreak setup so that it definitely breaks in the setup() function?
Thanks for Replying,
yes my platform.ini looks like this:
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
upload_port = COM8
monitor_speed = 115200
debug_tool = esp-prog
debug_init_break = tbreak setup
lib_deps =

olikraus/U8g2 @ ^2.28.8
bblanchon/ArduinoJson @ ^6.17.2
knolleary/PubSubClient @ ^2.8
What about this Error?
Error: libusb_open() failed with LIBUSB_ERROR_NOT_SUPPORTED
And line 238 is where setup() is?
What does the VSCode windows look like once the output SIGINT, Interrupt appears?
OpenOCD tries to open a few interfaces and fails with the wrong ones, then succeeds at the right one – can be ignored.
I set to Brakepoint one on line 237 Where setup() is and one on 244 for testing but this doesn’t made a differenz. First Picture without doing anything and Second Picture after Pause
What happens when you press the “pause” button in that moment?
What happens when you stop debugging, then remove all your two own set breakpoints and start debugging again? (The ESP32 has a lot of quirks regarding the number of available breakpoints and other stuff)
This is when i click Nothing:

Also this poped up after Step Out now:

Someone have any Idea i didnt get a solution yet?
What happens when you press the reset button after debugging has started?
Is the reset line / TRST correctly connected between the adapters? Maybe try new cables?
Reset button on the ESP Prog or ESP-32?
Try both buttons, I’d say
It looks like breakpoints were inserted at the wrong addresses. I think the partition table has not been updated to match the ELF settings. Try flashing the new table on to the chip. That should fix the problem.
Thats the message when i click Reset on Debugger:

Can you give me a link how to do it?
Follow the instructions here.
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/index.html
That will install the command line version of ESP32 development tools. Follow the procedure up to and including step 9. After that, the Platformio debugger should work until you do something to change the partition table.
Now it works but often i get another error:
Failed to launch GDB: .pioinit:11: Error in sourced command file:
Remote communication error. Target disconnected.: No error. (from interpreter-exec console “source .pioinit”)
Also the debug is very slow and sometimes it just stops on the way in the next row.
Slow down the JTAG clock by including this in platformio.ini
debug_speed = 12000
Stepping through code is slow on my system as well, 3 to 5 secs per step. I’ve seen it go much faster in other peoples’ setups.
