[SOLVED] Need help with ESP-PROG + ESP32 debugging

Postby filo_gr » Sat Mar 19, 2022 1:39 pm

Hello! I tried to setup the Openocd debbuger on VSCode to debug a simple software working in an ESP32 (This one, that is a DOIT ESP32 https://it.aliexpress.com/item/32799253 ... 3696TdQRqC).
I'm working with ESP-IDF v4.4 on Windows 11. I use the ESP-PROG to debug (https://it.aliexpress.com/item/33048891 ... 3696s7Mwsj).
I followed the tutorials explained in the following pages: I followed the instructions and I used Zadig to install the USB driver for the ESP-PROG.

The set-up I produced is the following:
  • My lanch.json

Code: Select all

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "espidf",
      "name": "Launch",
      "request": "launch"
    },
    {
      // nome personalizzato
      "name": "ESP32 OpenOCD",
      // cpp debugger
      "type": "cppdbg",
      "request": "launch",
      // percoroso del debugger, dipende da toolchain
      "miDebuggerPath": "C:/esp/tools/tools/xtensa-esp32-elf/esp-2021r2-patch2-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gdb.exe",
      // current working directory
      "cwd": "${workspaceFolder}/build",
      //change the name of the elf file as required (fare una build per trovarlo)
      // è del tipo nome_progetto.elf
      // usare copy path per andare sul sicuro per il percorso
      "program": "C:/Users/Filippo/Documents/Espressif/manual_debug/build/manual_debug.elf",
      "setupCommands": [
        {
          "description": "Enable pretty-printing for gdb",
          "text": "-enable-pretty-printing",
          "ignoreFailures": true
        },
        {
          // there's a bug in vs code that prevents us from using ${workspaceFolder} variable.
          // update the path as needed
          // stesso percorso messo prima
          "text": "file 'C:/Users/Filippo/Documents/Espressif/manual_debug/build/manual_debug.elf'"
        },
        {
          // configurazione openocd
          "text": "target remote 127.0.0.1:3333"
        },
        {
          // Limite di breakpoint hardware che supporta ESP32
          "text": "set remote hardware-watchpoint-limit 2"
        },
        {
          // reset ESP32 e lo blocca
          "text": "monitor reset halt"
        },
        {
          // flush dei registri interni esp
          "text": "flushregs"
        },
      ],
      "externalConsole": false,

      "logging": {
         "trace": true,
         "traceResponse": true,
         "engineLogging": true
      }
    }
  ]
}
  • ESP-PROG: Pin Vjtag to ESP32: 3V3
  • ESP-PROG: Pin GND to ESP32: GND
  • ESP-PROG: Pin TMS to ESP32: G14
  • ESP-PROG: Pin TCK to ESP32: G13
  • ESP-PROG: Pin TDO to ESP32: G15
  • ESP-PROG: Pin TDI to ESP32: G12
I'm using a simple code to test the debugger, if needed I can share it. However I think the problem is something else.

1) if I try to flash the ESP32 via the UART method (WITH THE ESP-PROG CONNECTED TO IT), It fails with the message:

Code: Select all

Uploading stub...
Running stub...Stub running...Changing baud rate to 460800Changed.
WARNING: Failed to communicate with the flash chip, read/write operations will fail. Try checking the chip connections or removing any other hardware connected to IOs.

2) To avoid this, I flash the ESP32 and after that I connect the pins of the ESP-PROG. I run the command

Code: Select all

openocd -f debug\esp32_devkitj_v1.cfg -f debug\esp-wroom-32.cfg
(the configuration file are copied inside my debug folder).
This is the output in this case:

Code: Select all

In other words, the debugger won't start. This is the first time I use the ESP-PROG.
Thank you

Look at this https://www.youtube.com/watch?v=LP4_UOl9wnU.
And please, open another topic if you encounter other problems ;)

Re: Need help with ESP-PROG + ESP32 debugging

I solved these problem, firstly by using another configuration file for the debug interface: the esp32-wrover-kit-3.3v.cfg.

1) This problem I think it's due to the fact the ESP-PROG is connected to the programming pins of the ESP32. Hence, if it is switched on during the programming of the ESP32, it could interfere with the programming procedure. To solve this I firstly program the ESP32 and then I connect the debugger.

2) This problem is a little bit strange: I noticed it happens often when I start the debug. To solve this I repeat the debug process until it works... :cry:
