I've set some configurations to Serial, and to use HardwareSerial transport mode. I am trying to debug the STM through two pins PB7 and PB6, so i'm trying to setup the debugger to use those pins.

Okay great, it is possible you have switched off automatic debugging or manually changed the debug setting to Off. You have correctly selected the Debug configuration but the debugging is OFF.

All you need to do to switch on serial debug with all the default values is to set "vMicro>Debugger>Debug = Serial"



tip: The debug settings are remembered per configuration name. Therefore when you have "Debug" selected as a configuraton you can set what type of debugging to use, when you have Release selected, you can set the debug to Off. Then all you ever need to do it switch between Release and Debug.

Ok now i'm trying again, all settings are reset to their default except the vMicro>Debugger>Debug = Serial setting.

But how will it know to use my specific PB7 and PB6 pins?

This is a confusing statement for me. previously you said you were just trying to use the standard usb cable that plugs into your board? 

The debug settings we are discussing work with the same connection that your serial in your own code uses.

No the setup i'm using is USB -> Nucleo-64 -> Dev board. I'm trying to debug with an FTDI1232 connected to pins PB7 and PB6. 
i just think my problem is that it can't communicate p
roperly between the breakpoint hardwareserial code and the PC? I have set up the debugger to us Rx pin PB7 and Tx pin PB6, and also set the speeds to 9600 baud and also set the remote transport mode to HardwareSerial (which i hope goes HardwareSerial serial = HardwareSreial(PB7, PB6)). But the vmicro debugger still receives nothing?

Okay it is best to be clear when you make the initial posts. How does your serial work? Does you code use Serial, Serial1,Serial2 or SoftwareSerial?

The serial works like:

Code (C++)
Select All
HardwareSerial mySerial = HardwareSerial(PB7, PB6);

Oh i see what might be the issue, i use HardwareSerial here and manually define the Rx and Tx pins but the debugger only accepts the built in uart definitions. I can define the pins using SoftwareSerial but for some reason the stm32 l452re doesn't work using the software serial (i will double check this now).

Yes, when i try to use

Code (C++)
Select All
SoftwareSerial mySerial = SoftwareSerial(PB7, PB6);

The PC doesn't receive anything at all.


When i use:

Code (C++)
Select All
HardwareSerial mySerial = HardwareSerial(PB7, PB6);


The PC receives messages.

Strange?

So i guess to make it work, i would need an option to provide HardwareSerial the remote Rx and Tx numbers?

Using this https://github.com/stm32duino/wiki/wiki/API#hardwareserial i am going to try to re-map the Serial3 to my custom pins, and then point the debugger at the Serial3? hopefully it works

it worked!!!!

To fix you must allow us to reconfigure the hardware serial parameters, but for now, a hotfix its just to re-wire the built in Serial definition like this:

Code (C++)
Select All
HardwareSerial Serial3(PB7,PB6);



and then configure the debugger like this:

Ah great. Thanks. We will try to extend the docs for that configuration.

Did we resolve this issue? There have been updates for both debug and stm32 in the latest releases(s) available here.
