MSPM0G3507: MSPM0 Flash settings

Hi Kei,

What tools are you using to program the device? Specifically what IDE and what debugger?

Are you using Sysconfig?

That message indicates that there is some portion of your program allocated to NONMAIN memory for some reason. Since its not being erased it isn't being reprogrammed, but if you're not careful writing to NONMAIN you may accidentally lock yourself out of the device.

Thank you, Brandon.

I have described my environment.
・Code composer Studio 12.4.0

・XDS110

・Use sysconfig 1.17.0

I use ECC to write to NONMAIN.
Also, the linker file fills the Code area with values.

What is your MSPM0 SDK Version? The latest is 1.20, and I believe it requires SysConfig 1.18. There are some bug fixes included but I don't believe that is the cause of your current issue.

Are you saying you are writing to the ECC corrected area of NONMAIN, that is fine and the best area to write to. If you are intentionally modifying Nonmain then I would encourage you to use the SysConfig tool to do it, rather than modifying it on your own. You can become permanently locked out of the device if you are not careful. If you are using sysconfig to do this then of course you should be fine.

If you are intentionally modifying non-main, you must also set your debug configuration to erase the non-main region of flash memory before it is programmed, or you will get the error you are seeing.

To do this, first right click on your project name in the project explorer, and go to Debug As -> Debug Configurations:

Then in the debug configurations change the erase method setting for your project as described below:

The default linker shouldn't fill this, it should just ignore it if no coded is to be loaded. Have you modified the linker at all?

Thank you, Brandon.

SDK is using 1.10.0.05. This will be replaced with the latest version in the future. It has not yet caught up with the changes.

I'm sorry, but I don't really understand how to change Nonmain using the Sysconfig tool, so I don't use it.

I would like to manage data in a specific area with the linker. Therefore, we are filling part of the area of Code (Flash) ECC Corrected.

I have used Debug Configrations to some extent.
I'm Flashing a program with a two-step configuration.
1.
Erase Main memory only
Flash 0x0000~0x1FFF
fill from 0x2000 to 0x3FFF

2.
Erase Main memory Sector by range( 0x2000 ~ 0x3FFF)
Flash 0x4000~0xFFFF

Perhaps the cause is that there are two configurations, BCR_CONFIG and BSL_CONFIG.

Hi Kei,

BCR_CONFIG and BSL_CONFIG are included in the default version of the linker, and shouldn't trigger that message unless you are also filling those regions. 

If you flash a new example from the SDK do you still see this error?
