IAR-Compiler und CSpy-Support?

[Schloern93]

Hello Togehter,

I use the IAR Compiler in IAR Embedded Workbensh 8.5. As controller I used a stm32g491re. FreeRTOS is running on the controller. Debugger is the ST-Link V2.
Unfortunately I can't get the RTOS Views to run. So I wanted to ask if this setup is supported.
Enclosed is an excerpt from my launch.json

[{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "cspy",

                "--fpu=VFPv4_SP",

                "--rtos=FreeRTOS"
            ],
            "download": {
                "flashLoader": "C:\\Program Files\\IAR Systems\\Embedded Workbench 9.2\\arm\\config\\flashloader\\ST\\FlashSTM32G49xxE.board",

                ]
            },
            "setupMacros": [
                "${workspaceFolder}\\CMakeBuild\\DevelopmentUsingIAR\\KlimaK8_DebugInfo.mac"
            ]
        }
    ]
}]

This ist the error message of the RTOS Views

RTOS Views: Session Name: "Application with free rtos", FreeRTOS detected.
Unable to collect full RTOS information.

Many thanks for your help in advance

See if there is a way to get logs from cspy as to why requests from rtos viewer are failing. The cspy debugger has to provide/support memory/variable read requests without which we cannot do anything. We do not have access to IAR tools at the moment. We do not use anything specific to any debugger. We use Microsoft's Debug Protocol Specification to work with all debuggers.

After the debugger pauses, did you try 'Refreshing' the RTOS view? Single stepping will force an automatic refresh. There is also a command to manually refresh the RTOS panel in the VSCode Command Palette

Sometimes, it is a matter of timing where the debugger moves on and refuse request will the debugger is running. Most debuggers will only allow requests while the debugger is in paused/stopped state.

Hello,
I have already tried all the steps. Unfortunately without success.
This is the output in VsCode in the developer window if im trying to fefresh the window.

This is the output in the XRTOS terminal after I tried to reload the window and my programm stopped at a breakpoint
RTOS Views: Busy updating...

I've never seen such a message. What is the 'VSCode in the developer window"? Never seen that either.

Can you send a screenshot of this window?

[PhilippHaefele]

Seems the screenshot is from the VSCode Developer Tools which are the https://developer.chrome.com/devtools of the Electron "runtime".

@Schloern93 Is there really nothing else from C-SPY side that shows the memory or internal VSCode calls done?

The log message is from https://github.com/mcu-debug/rtos-views/blob/main/src/rtos/rtos-freertos.ts#L743

@Schloern93 As there really nothing issue is quite old now. Just to not waste time, can you still see this issue in the latest version?
