ESP32 & PIO Unified Debugger

There is a debug problem on Espressif32 v1.1.2 platform that affect C++ code debugging.
This affect ESP-IDF C++ code and Arduino code.
C++ code can’t be debugged properly since “load_cmd”: “preload” was removed from platform.py.
Please bring back that command to release branch, or find some other way to fix this problem.

Thank you.

Thanks for the report! You can control this behavior manually via Redirecting...

[env:...]
board = ...
debug_load_cmd = preload
  • What is your OS?
  • Do you see any errors with v1.1.2?

Could you also try the latest upstream version Espressif 32 — PlatformIO latest documentation ?

I tested on Windows and on Linux (mint)

Here is a test project:


It won’t stop at the brakepoint on Arduino code or ESP-IDF cpp project.
Work’s just fine when using ESP-IDF and C project.

Tested the upstream branch, commit #1610bd1 and this one work’s just fine with debug, but present the same problem on “Skip pre-debug” option.
However, the “debug_load-cmd” flag on platformio.ini file save the day in those sittuations :slight_smile:

Do you mean that it does not work only with “Skip Pre-Debug”? It seems that I know where is the problem.

Using upstream branch, commit #1610bd1, no “debug_load_cmd = preload” in ini file:
-“PIO Debug” option, C++ debugging work’s just fine.
-“PIO Debug(Skip Pre-Debug)” option, C++ debugging don’t work properly.

Adding “debug_load_cmd = preload” option on platformio.ini fix the debug problem.

New PIO Core+ has been released today! Please open PIO IDE Terminal and type

pio upgrade --dev
pio update

Does it work now for “PIO Debug(Skip Pre-Debug)” ?

I am using PIO Home 1.0.0·Core 3.6.0a8
“PIO Debug(Skip Pre-Debug)” work’s on C++ code only with “debug_load_cmd = preload”

Using that debug command on ini file, don’t bother me.
As long it work’s, is good enough for me.

side note:
It seem’s that “PIO Debug” is faster now :slight_smile:

  1. Please clean project via Tasks > Run Tasks… > PlatformIO: Clean
  2. Start PIO Debug(Skip Pre-Debug) without debug_load_cmd = preload.

It should work. If it does not, need to find out why :frowning:

Yes, we did great improvement. Now, is so close to make an official announcement that support debugging ESP32 .

P.S: Thank you so much for your feedback!

I check’t few times more and it look’s like Skip Pre-Debug is working sometimes without the preload cmd too.

I also noticed the “Pio Debug” option is not loading the program to target before debug.

I think you should set the current “Pio Debug” setup to “Skip Pre-Debug” option because is fast,
And set the “Pio Debug” to how it was before: load the program to flash before debugging.

Anyway, this are small details…
In my opinion, PIO Debugger is a big achievement because make’s “ESP32 1 Click Debug” possible.
Anyone who ever made a GDB set up, understand’s what i’m saying… :grin:

Thank you for making it this easy to use.

We do loading but through OpenOCD, not via python/esptool. It is faster. Could you provide me an output from “Debug Console” when it “does not work”? Right click on a text in “Debug Console” > Copy All.

Thanks!

Thanks! Do you use Zadig tool?

Yes. I set the ft2232 channel 0 to WinUSB for debug and channel 1 is using ftdi drivers (com port)
I never tested with both channels on stetted as com ports…
I know that GDB require libusb on windows for ftdi based Jtag’s.

Could you provide a screenshot here? I would like to add this information to our docs. I think it’s so useful. Also, would be thankful if you explain in a few words what need to configure.

  1. Download and install FTDI drivers from http://www.ftdichip.com/Drivers/VCP.htm

  2. Connect the debugger to PC USB and check the device manager to see if the drivers are installed properly:

  3. Download Zadig tool from https://zadig.akeo.ie/

  4. Open Zadig Tool and go to Options->List All Devices
    zadig1

5.Select the FT2232 channel you want to use as Jtag.
In case of Wrover-Kit, is channel 0: “Dual RS232-HS (interface 0)”, according to Wrover-Kit schematic:

wrover-jtag

If you use FT2232h minimodule, you can use any channel.
The debugger work’s with FT4232h minimodule too (tested).
In this case, you have 4 channels to chose from :slight_smile:
It work’s even with cheap FT232x chip (ex. UM232H , UM232H-B modules).

  1. Select WinUSB
  2. Click Replace Driver

Capture2

After operation completed, disconnect and reconnect the device to USB port

Now you can use PIO Debugger on ESP32

PS.

In case that other channel (channel 1 in case of wrover-kit) is not detected as com port (used by esptool for flashing),
you must enable the VCP mode on channel 1, this way:

  1. On device manager, right click on “USB Serial Converter B” - >Properties ->Advanced
  2. Select “Load VCP” then click OK.

vcp

Then, the FT2232 channel 2 should be detected as Com Port on device manager:
