Using the default linker file, (lnk_msp430f5438a.cmd), code using the "large" model will fail. Message will say that space has run out in section FLASH.
It looks like it wasn't seeing that FLASH2 was available.
A line in the command file looks strange:
.text : {} >> FLASH | FLASH2 /* CODE
I changed it to single arrow:
.text : {} > FLASH | FLASH2 /* CODE
And that fixed the problem. You guys probably need to fix this the next update.
