MSP430FR5994: Project Build Error with MSP430 GCC compiler

What do you see at line 59 of lnk_msp430fr5994.cmd [in your project]?

In mine (CCS v12.6) line 59 says:

    TINYRAM : origin = 0xA, length = 0x16

I don't see any obvious syntax error here, but the linker can be finicky.

GCC, at least in the Linux version for the MSP430, uses linker scripts with the suffix ".ld". They are different from the .cmd version.

MEMORY {
  TINYRAM          : ORIGIN = 0x000A, LENGTH = 0x0016 /* END=0x001F, size 22 */
  BSL              : ORIGIN = 0x1000, LENGTH = 0x0800 /* END=0x17FF, size 2048 */

The man page for ld doesn't say anything about case sensitivity:

"   The ORIGIN is an numerical expression for the start address of the
memory region.  The expression must evaluate to a constant and it cannot
involve any symbols.  The keyword ‘ORIGIN’ may be abbreviated to ‘org’
or ‘o’ (but not, for example, ‘ORG’)."

Editing the linker script to make those keywords lower case resulted in a syntax error. So the fault is with not using the GCC specific linker scripts.

Hi Bruce, thank you for your response. In mine (CCS v20.1.1) line 59 also says same:

    TINYRAM                 : origin = 0xA, length = 0x16

I created an empty project with CCS v12.7.0 using GNU v9.3.1.11. It generates a GCC-specific linker script (".ld") as David mentioned, instead of the default ".cmd" file, and compiles without errors.

The issue arises with Theia. In Theia, I can only create new projects from provided examples, which are set up with the default TI compiler. I cannot change the compiler to GCC directly. The project is created with a ".cmd" file, and when I switch to the GCC compiler afterward, I encounter the build error mentioned earlier.

When I import a project from CCS v12.7.0 with the ".ld" linker script into Theia, the project is not recognized and does not work. Is there any way to create an empty project with MSP430FR5994 using GCC compiler in CCS Theia?

Hi Hassan,

Thanks for the feedback. I think the issue is located at: "when change the project compiler in CCS V20, the corresponding cmd file is not generated". I will report to CCS compiler team to see any recommendation.

================================

Updated: See below thread, it consider to add back this feature in future release version.

================================

By the way, if you manually copy the .Id from CCS to CCS Theia, does it work fine?

Hi Sal,

Thank you for your response.

The thread you mentioned in link is talking about some example project was not created or connection issue. Are you reffering to some other thread ?

Yes when i manually replace lnk_msp430fr5994.cmd in CCS Theia with msp430fr5994.ld from CCS. It compiles fine. No more linker issue.

I mainly want to update that CCS team consider add the feature back (create new project seperately).

Yes, this is a known issue that we plan on addressing in a future CCS release. The current workaround is to create one from the command line:
