Issue in MbedProject on STM32U5 board

[mgraceltis]

Hello,

I started a mbed project on NUCLEO_U575ZI_Q board, and i have some issues with clang intellisense (I think)

Here is a dummy source code for exemple :

#include “mbed.h”

Ticker ticker;
bool ledSwitch = false;

int main()
{
DigitalOut led(LED1);

ticker.attach(callback([](){
ledSwitch = true;
}), 1000ms);

while (true) {
if (ledSwitch)
{
led = !led;
ledSwitch = false;
}
ThisThread::sleep_for(1ms);
}
}

In this exemple, clang intellisense make an error on “ticker.attach” : [Clang IntelliSense] Error : no matching member function for call to ‘attach’ test C : \Users\maxime\Desktop\test\test\main.cpp 10
I have this error too : [Clang IntelliSense] Error : “Unknown ARM architecture for exclusive access” test C : \Users\maxime\Desktop\test\test\mbed – os\platform\include\platform\mbed_atomic.h 95
However, the code compiles and runs correctly on the boards.

I tried with another board (NUCLEO_L496ZG) and everything works perfeclty with no error from intellisense.

Setup :
Windows 11
Visual Studio 2022 17.8.11
VisualGDB 6.0R3 build 5191
GCC 9.3.1

Thank you

Hi,

Thanks, looks like the U5 port is using a couple of built-in functions that are not known to Clang and somehow trigger strange behavior.

We have added a workaround on the VisualGDB side. Please try this build: VisualGDB-6.0.103.5197.msi
