Hello
This message seems to indicate that your board is not configured properly.
Actually the debugger is not able to write to address 0x20400000.
Can you check the following:
- Are you using the appropriate register configuration file?
This file is specified in the "SC Debugger Target" panel from the "Target settings" dialog.
- Are you using the appropriate memory configuration file?
This file is specified in the "Remote Debugging Options" panel from the "Target settings" dialog.
If you have a PC where this was working, please check which files are specified there and also check the difference between these files and the one you are using on the new Host.
I hope that helps.
