How to configure Flash Programmer

[davidzhou]

Hi,

I have K60 tower board: MK60FN1M0VLQ12

I am using Multi-Link FX for downloading program into flash.

In my MQX project, I need to reserve some flash memory for program configuration data. Every time when flash program is downloaded, the flash programmer erases whole 1M flash memory. How do I configure flash programmer that not to erase al flash memory, or only upto the size of the program?

Thank you,

David Zhou

Hi.

In a debugging session, the CodeWarrior Attach launch configuration skips setting up the target hardware and downloading the program image to that target hardware. that's to say, with "Attach", all flash memory on chip will not be erased during hardware connect.

Have a great day,

Hi David:

I think you can edit the flash loader to do that.

Please check the following picture , if you are using IAR .

Hi David

For code warrior, please click the Advanced Programming Options in Hardware or simulator connection. Then you will see the Non-Volatile Memory Preservation.

Hi Daniel,

I change the flash memory as :

Program size is less than 0x60000.

But it loaded, and I got runtime error.

I also tried Enable Flash Programming Dialog. It didn't show the dialog. It displays loading info into console. and I got the same runtime error. GDI connection lost.

Thank you,
