Hmmm, I guess the mspgcc4 isn't generating the required calla/reta instruction for the far calls. For own code, it could be fixed by simply doing a search&replace on the generated intermediate ASM files. (requires tweaking of the makefile). AS and LD support the full 430X instruction set almost properly (even in the non-X branches) But if the linked stdlib/gcclib does not contain the proper reta instructions or e.g. the multiplication/division code or any library functions, then it still won't work. Putting constant data into far flash is more difficult.

But the execution of the program is not ok. With the same program: when I load only in the flash1, the execution is ok. To use the flash2 with my program in the compilation mspgcc4, I used the command "__attribute__((section(".fartext")))" before several functions. I'm going to check if the options of my compilation mspgcc4 are good. Perhaps that I must use a specific option with mspdebug to load the format large_memory_model?
