Azure Sphere RT Core Update Failed

Hi,
I've developed with the USI Azure Sphere Dev Kit Board, and the installed SDK version is 21.10.
I'm trying to run the UART real-time core sample code (mt3620-m4-samples), but the VS shows device update failed.

Do you have any ideas?
Tell me if you need more infos.

P.S:
1. The rt-core-debugging has already been enabled.
2. The MSFT MT3620 Std Interface driver has already been installed.

3. The high-level application can normally operate.

Hi,
Thanks for providing the setup environment, I found that the problem is my hardware setup, which is replied to above, after the SWD interface is connected, the sample works fine.

Hi @FrankHsieh-5045,
Can you confirm that before trying this sample you successfully Build and run the HelloWorld RTApp application with Visual Studio ? When we complete this tutorial it helps us confirm that the setup to build a sample application for the real-time cores on an Azure Sphere device is correct.

Thanks!

Hi,
Thanks for your comment, after checking the mt3620-mcu-program-debug-interface, I found that I forgot to connect the SWD interface, which is needed for RT core debugging.
After connecting the SWD interface, the sample is working.
