armdbg cannot connect via ST-Link on Nucleo-H7S3L8

[doesnotcompete]

Type: Bug Report

Describe the bug

• OS and Version: Arch Linux/Linux 6.10.7 x86_64
• VS Code Version: 1.92.1
• Extension Version: 1.2.2
• Target Device: Nucleo-H7S3L8/STM32H7S3L8Hx
• Interacting with the on-board ST-Link on the Nucleo fails with ERROR(TAD517): Failed to connect to any devices on the target. Check that the target is correctly connected to the debug probe and powered on.

To Reproduce
Steps to reproduce the behavior:

1. Add the STLink to the Device Manager and configure pack and device name.
2. Add a debug/launch configuration.
3. Attempt to run or debug the solution.

Expected behavior
The connection to the on-board ST-Link is successful.

Thanks for reporting this, @doesnotcompete !

Could you please check if adding the option "connectMode": "underReset" makes a difference? Depending on the application residing in the device's flash before programming/debugging, it may be in a low power mode with the debug logic turned off. This option can help to recover from such state.

Also, if this doesn't help, could you please run the debugger with the command line argument --log-debug-sequences instead of -l DEBUG and post what's logged for sequence "DebugPortStart"? I'd be interested to see if you are hitting a problem that we are currently looking into a fix for and that can show the above symptoms.
