Information in this article applies to:

• ULINK USB-JTAG Adapter
• ULINK2 USB-JTAG Adapter

QUESTION

Is it possible to dump or save the contents of target mamory using the ULINK with µVision? I have an application that modifies pieces of the memory and I need to verify if the modifications are done correctly by reading out the memory of my application.

ANSWER

Yes, it is possible using ULINK. To ensure that ULINK reads the memory contents of the target system, you need to disable all Cache Options under Project — Options for Target — ULINK Settings. Then you may use the following µVision commands:

• Use the SAVE command to store the memory content as a Intel HEX file.
• Use the LOG command to protocol the Output Window to a file. Then you may use the Display command with start/end address to get the content of the memory.

MORE INFORMATION

• Refer to Display in the µVision® User's Guide.
• Refer to LOG in the µVision® User's Guide.
• Refer to SAVE in the µVision® User's Guide.
