Placing Code into Specific Section using MSPGCC toolchain

Silver Diamond

I am converting my code to TI MSP GCC compiler and I am trying to figure out how to place code into a specific memory section, for example, using TI C/C++ compiler I used the following pragma:

#pragma SET_CODE_SECTION(".BSL")

#pragma SET_CODE_SECTION()

How do you accomplish for MSP GCC?

I'm not aware any GCC function attribute, or anything similar, which has the same effect as SET_CODE_SECTION. The function __attribute__ ((section ("name_of_section here"))) can be applied to one function, but not to a range of multiple functions.

Thanks and regards,

OK, this is what I have thus far:

#if defined(__TI_COMPILER_VERSION__)                            //  <= TI C/C++ compiler
#pragma SET_CODE_SECTION(cBSL_main, ".BSL")
#pragma RETAIN(cBSL_main)
#elif defined(__GNUC__)                                         //  <= GCC compiler
void cBSL_main(void) __attribute__ ((section (".BSL"), used));  // <==== Does this look right? 
#endif
void cBSL_main(void) {
    // my code here ...
}

I will see if it works shortly

If you only need this source code to work with the MSP430 TI and GCC compilers, then you can just use the __attribute__. It works the same way with both compilers.

Thanks and regards,

Awesome, this cleans up code considerably.
