Serial debugging wont start?
Feb 18th, 2020 at 1:59pm
 
Hi,

I'm trying to run the SoftwareSerial debugger however i get this message when i try to debug:

Quote:
Debug Build Error: This hardware might not support the default Visual Micro Debugger.
     If this project is using OTA/WiFi upload then please use the vMicro>Debugger menu to set the Serial COM and Remote port for the debugger.
     Otherwise switch the toolbar from 'Debug' to 'Release' and build again.
           or switch off Automatic Debugging
           or configure the SoftwareSerial debugger option.


For the software serial i have attached an FTD1232 to pins RX 21 and TX 10 on my board (they do not correlate to any hardware UART).

To upload the code i am using the SWD pins on the STM32 (TCK/TMS), which are on different pins to the serial debug port.

Here are my settings for the debugging:

...


...

I'm confused as to setting this up, i think i've configured it correctly but how can i define a Remote Port if the Remote Transport mode is SoftwareSerial? I'm not sure if this is the issue, please help!


Thanks!
Richard

Currently you have to set the software serial option in the visual micro project properties tool window.

You will see in the debugger section of the properties are the same properties you see on the vMico menu + some more.

Please see this documentation:-

Ok thanks Tim, what do i use as the remote port when using the software serial mode? i've defined the Rx and Tx pins so shouldn't it be independant from any hardware/serial port?


But at the moment when i compile in debugging enabled mode i get this error?

'VisualMicroDebug::begin(HardwareSerial*, int)


I'm using an STM32 Nucleo-64 L452RE

You are correct, you do not need to specify the remote port for software serial.

Software serial doesn't like 115200 speed, use 56k or below. Set the Remote speed and the local speed should automatically change to same.

Ok, does the -g flag affect anything?

I've got some more errors from VM_DBG.h

Quote:

VM_DBG.h:397: note  candidate  void VisualMicroDebug  begin(SoftwareSerial*, long unsigned int)

and also this too:

Looks like software serial is broken in the last few versions. we will try to fix over the coming day or so.

In recent builds the software serial debug failed for breakpoints outside of the project_name.ino however the error was different.

There is an updated build (20.02.16 sp1) but I suspect you settings are wrong and the current error you haveis probably unrelated.

Please confirm that you have not added a RemotePort=? Look at the vMicro>debugger properties and click the "Reset" option, then use the F4 project properties to set the RemoteTransport, LocalPort and tx/RxPins.

Ok i have reset my debugger options and setup the RemoteTransport, LocalPort and Tx/Rx pins, and it all sets up correctly.

Problem is that its not printing anything to the port monitor if i set a breakpoint action or breaking the program at all if i hit the breakpoint?

I might need to see your zipped project but let's first make sure you are doing what you want to do.

Did you pick the softwareSerial debugger because you want to keep your code uses serial.read() on the main usb port?

No, i'd like to use the nucleo-64 for the entire thing, the code does no serial reading.

I'm just checking if the program i'm running is running OK.

Clear/reset all the debug settings. Ensure the tool bar is set to "Debug". Add a breakpoint and click upload.

If the debug does not start then follow the guide in yellow above so we can see your settings.

There is nothing to configure for usb debug. The software serial option is something different.

Please follow my previous request. I suspect there might be or or maybe two confusions

1) Debug is not enabled. Either automatic debugging has been switched off or the debugger type set to off. The guide in yellow above will show us what we need to know.

2) Debug is off and the serial monitor speed has been altered to be different from the speed set in the sketch code.

Let's see the output from the yellow box before continuing.

Thanks

Ok i can get the sketch to compile and then run, it enters the debug view, but nothing happens when it passes a breakpoint?

Normally you just switch the configuration name on the tool bar between Release and Debug. Visual Micro automatically switches the Serial debug off/on.

However you can override the automatic setting in which case you would need to ensure that "Serial" is the selected debugger type.

When the build happens it says "compiling project x" or in debug mode it says "compiling debug version of project x"

If you have been changing settings I recommend starting a new project with a simple test so that you can see a breakpoint work and also see that you need not change any settings other than switching between Release and Debug.

It is impossible to assist further without the information request in yellow above. Otherwise I have to guess at what settings you have changed.


See the docs

Ok no problem, sorry i'm just trying different configurations, it takes so long to build! I think that because its not printing to the Serial Monitor within vsmicro it must be that the port is setup wrong in the configuration.

Am i ok putting "PB7" "PB6" for example in the Rx and Tx pin boxes? what input do they expect?

The build log is as follows:
https://pastebin.com/T8ySUXZU

The micro debug trace output prints:
Launching Debugger...

The serial monitor prints:
Port closed
Opening port
Port open

--

Strange but the internal Serial window isn't printing anything i sent to it at all?

You have still got the softwareSerial configured which as I said is NOT what you want. You do not need to add a tx/rx pin you do not need to set any debug properties.

Please click the Reset on the vMicro>debugger menu then clear the value you have assigned to RemoteTransport in the project properties.

I can also see that you have switched off deep search for libraries. That is not causing an issue but will do in the future.

I think your big problem is the compile time. That is way too long and most certainly caused by your virus checker.

You could try exclusing this path from your virus checker or try with it off to see the speed difference.

I've completely reset all the debugging settings so everything is empty. I pressed the debug button, but now it compiles and runs but no debugging happens at all?

This is the complete build log:
