Can DSTREAM-ST with DS2021 Debug cortex_a55 board?

Dear arm experts,

I try to debug my baremetel code on cortex_a55 boards(RK3568 SoC) with DS2021. When using DStream ST to connect the board, I encountered an error message: 'Failed to power up ARMCS-DP'.

How can I solve this problem? Do I need to update the version DS to obtain support for the Cortex-a55 boards?

Looking forward to your reply.
