What causes the error message： Failed to stop process?

On my P2020 platform, using the emulator to download the tcl file, I get the following error：

Failed to stop process
[CCS last error: ELF is not in expected HALT mode ](CCSProtocolPlugin)

-------------------------------------------------------------------------------------------------------------

Using the above configuration on another project, successful download；Download fails in new project。

The difference is that the new project's DDR uses ECC。

What causes the error message： Failed to stop process

                                                      [CCS last error: ELF is not in expected HALT mode ](CCSProtocolPlugin)

If it is an error caused by ECC not configured, how do I configure ECC for DDR?

Can anyone help me?

Thanks！

Is the problem solved, and if so, how?

[ufedor]

The error message "CCS last error: ELF is not in expected HALT mode" means that the core can't be controlled by the debugger.

To check whether the issue is caused by the DDR controller ECC replace the following script line:

cmdwin::mem p:0xe0002110 = 0xE7000000

with

cmdwin::mem p:0xe0002110 = 0xC7000000
