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.
Hi againThanks for checking your SoC manual. Yes, it looks like the SoC supports both SWD and JTAG debug connections.I still believe the most likely cause of the problem is that the ARMCS-DP is powered-down. It is quite common for this to be controlled by a power-control subsystem, which needs to be activated first.Take a look at the RK3568 TRM, Chapter 7 Power Management Unit (PMU)Stephen
