Problems using Visual Micro to upload firmwate to Portenta Machine Control

Hi all,

I use Visual Micro extension for Visual Studio 2022 (both are updated to the latest available versions) to build and upload code to many Arduino boards.

In this period I am developing some pilot applications for the Portenta Machine Control (PMC) board (https://docs.arduino.cc/tutorials/portenta-machine-control/user-manual/); it is based on the Portenta H7 architecture.

Code compilation succeeds but the upload process fails systematically with the following output:

Code

The same sketch compiled with the Arduino IDE for the same board connected to the same USB port is correctly uploaded with the following output:

I also tried to launch VS with administrative privileges, but the upload to PMC always fails.

May I ask for some help with this problem?

Is there any other user who uses VM to compile/upload code for/to a PMC?

Any help wil be appreciated.

Cheers.

Thanks for the report.

While we investigate this can you confirm that manually putting the board into Upload mode allows the upload to succeed in Visual Micro (double tap the reset button should trigger Manual Upload Mode).

Yes, manually putting the card into upload mode solves the problem: the upload process completes successfully!
I wasn't aware of this workaround.

If you add a Local Board.txt to the project (vMicro > Add Code > Add Local Board.txt) and add the below content, this should ensure the upload works correctly:

Code (C++)
Select All
upload.use_1200bps_touch=true
vm.1200bps_touch.SetDTRFalse=true

Yes, also this workaround works well! This is the result of the compile/upload command:

Code
Select All
Compiling 'OPTA-PMC_SerialRTU' for 'Arduino Portenta H7 (envie_m7)'
Build Folder: "file:///D:/Junk/VMBuilds/OPTA-PMC_SerialRTU/envie_m7/Release"


Uploading 'OPTA-PMC_SerialRTU' to 'Arduino Portenta H7 (envie_m7)' using 'COM13'
Uploader started for board Arduino Portenta H7 (envie_m7)
Upload method will be: bootloader
Uploading via Bootloader
PORTS {COM13} / {COM13} => {}
PORTS {COM13} / {COM13,COM14} => {COM14}
