AWR2944: CCS debug error (unable to write memory)

Tool/software:

Hello,

I am working with the AWR2944 radar board and DCA1000EVM. My goal is to capture raw ADC data and eventually modify the MSS firmware (without relying on mmWave Studio).

Setup:

• AWR2944 board connected via XDS110 (USB) to CCS 12.

• mmWave MCU+ SDK 04.07.01.03 with DFP 02.04.18.00.

• CCS builds: out_of_box_2944_mss and out_of_box_2944_dss both build successfully after fixing post-build Node.js path issues.

Changes made:

• In MSS SysConfig I disabled IPC/RPMessage since I only need MSS for raw data at first. However, I later had to also build DSS because the demo image depends on both MSS and DSS.

Problem:

• When I try to debug/load the MSS binary (out_of_box_2944_mss.xer5f) in CCS, I get this error:

•  (Error -2062 @ 0x0) when using SOP011 - development mode.

• (Error -1065 @ 0x40) when using SOP101 - flashing mode.

context: 

Cortex_R5_0: Trouble Writing Memory Block at 0x0 on Page 0 of Length 0x40: (Error -1065 @ 0x40) Unable to access device memory. 
Cortex_R5_0: File Loader: Verification failed: Target failed to write 0x00000000
Cortex_R5_0: GEL: File: ...out_of_box_2944_mss.xer5f: Load failed.

Questions:

1. Which SOP mode should I be using for JTAG debug with CCS? (I currently tried 011 for development and 101 for flashing, but I still cannot load to memory).

2. Is there a specific load sequence required (MSS first, then DSS, then RadarSS) to avoid this memory access error?

3. Are there any additional CCS target configuration settings (e.g. TCLK speed) I should adjust for stable debug on AWR2944?

4. Should i re-enable IPC/RPMessage? 

Thank you in advance.
