Compilation error on Teensy 4.1

Development Platforms

Hi,

I am receiving a compilation error on a Teensy 4.1 with a very simple code. It has worked well previously, so I am suspecting some updates but can find out what has happened. I am using PlatformIO on Visual Studio on Windows 10.

The code is as follows.

#include <Arduino.h>

void setup() {
  analogWriteFrequency(2, 9000000);
  analogWrite(2, 128);
}

void loop() {
}

The compilation message is:

> Executing task in folder Teensy4pt1Evaluation: C:\Users\grbo\.platformio\penv\Scripts\platformio.exe run --target upload <

Can anybody give me an idea of what is going on and help me to solve this issue?

Please remove the folders

  • C:\Users\<user>\.platformio\.cache
  • C:\Users\<user>\.platformio\packages\toolchain-gccarmnoneeabi*
  • C:\Users\<user>\.platformio\packages\framework-arduinoteensy

and rebuild the project.

I just did and obtained more or less the same results:

Do you have an antivirus that could block execution somehow? This does noot look healthy.

When you open a CLI and execute

C:\Users\%USERNAME%\.platformio\packages\toolchain-gccarmnoneeabi\bin\arm-none-eabi-g++ --version

what does it say?

Hi,
I am using a work laptop so there is an antivirus and managed by my employer I guess. It have the possibility to add exclusion though. I have never had any problems previously with execution blocking with VSC, but new updates that I am unaware of might cause problems now…

Under is what I obtain after the command you suggest:
arm-none-eabi-g++.exe (GNU Tools for ARM Embedded Processors) 5.4.1 20160919 (release) [ARM/embedded-5-branch revision 240496]

This is correct – so the compiler can be executed from a shell, but not by PlatformIO? Weird. The only instances where I’ve seen this is as said, with very aggressive antivirus systems.

Can you again open a CLI and run

pio run -j1 -v

for a verbose, single-threaded compilation and post the log?

Here it is:
