CCSv6 Changed device but still picks up old header file

Other Parts Discussed in Thread: MSP430F5438, MSP430F5438A

Hello,

We have a project that has outgrown the MSP430 that we originally selected and I have been tasked with porting to the new device.

My first step was to go to project settings and change the device under the 'General' heading.  I then rebuilt and began remapping the I/O.  That's when I noticed that, even though the IDE has the new device selected in project settings, it is still pulling in the header file (in ccsbase/msp430/include/)  for the old device instead of the header for the new device.

I then grep'd the project directory and discovered that the .ccsproject and the .cproject files still reference the old header.

Are there some other additional steps that I am supposed to do to change devices in an existing project?

Regards,

Mark Rush

    Hi Mark,

    How does your Project -> Properties -> Compiler -> include options look like? Does it include previous MSP430 folders?

    With CCSv6 when the device is changed under the CCS Project Properties -> CCS General, then under the CCS Project Properties -> CCS Build -> MSP430 Compiler -> Advanced Options -> Predefined Symbols CCS should automatically change the predefined name of the form __<device_name>__ to match the new device. It is the __<device_name>__ predefined symbol which the msp430.h generic include file uses to select the device specific include file.

    With CCSv6 I tried changing the selected device from a MSP430F5438A to a MSP430F5438 and the predefined symbol changed as expected from __MSP430F5438A__ to __MSP430F5438__

    How did you determine that the header for the old device is still being used?

    According to Reused an MSP430G2755 project for MSP430F5310. Changed device type - .ccsproject still shows 2755 the .ccsproject only contains a snapshot of some settings when the project was created, so don't believe that it is a problem that the .ccsproject still references the old header.

    In the test where the device type was successfully changed then:

    - The .ccsproject file only referenced the original device

    - The .cproject file referenced the new and original devices

    Does this match what you found in the .ccsproject and .cproject files?

    Thank you all for the replies.  I finally resolved the issue by creating a brand new project and manually copying old source code into it.  Probably not the most elegant, but it works.
