How to Capture a Full ICSSG Memory Dump

A full ICSSG memory dump is useful for in-depth debugging of industrial protocol issues. There are two methods to capture this.

Method 1: Using devmem2

Run the devmem2 utility on the target to log the ICSSM register space:

This method requires JTAG access to the board via CCS. If JTAG access is available, this approach is generally faster than using devmem2.

In CCS, launch the Target Configuration for AM263PX.
In the Debug window, right-click on any core and select Show All Cores.
Connect to the CS_DAP_0 core.
Open the Memory Browser via View → Memory Browser.
In the Memory Browser toolbar, select System View.
Right-click on the memory area and select Save Memory.... Follow the instructions in the dialog that appears.
In the dialog, configure the following:
- Start Address: ICSSG base address for the instance being used:
  - ICSSM0: 0x48000000
- Memory Page: System_View
- Number of memory words: 0x40000
- Format: 32-Bit Hex – TI Style
