I move a project from CCS 6.1 to CCS 6.2. Along with that, the compiler version went from 4.2.2 to 16.9.1. The expected entry point for the firmware is 0x8000. It has to be there to work with the bootloader.
This entry point is controlled by the following lines in the linker command file:
.boot > 0x8000
{
-l rts*.lib<boot.obj > (.text)
}
For compiler 4.2.2, this placed the entry point at 0x8000. However, for compiler, 16.9.1 it no longer works. I expect that there is no longer a section named .boot in the rts library.
I need to get this working ASAP. Any help would be appreciated.
I have attached 3 files.
A GREP excerpt of the map file showing instances of rts430 OR 8000 with compiler 4.2.2.
A GREP excerpt of the map file showing instances of rts430 OR 8000 with compiler 16.9.1 LTS.
An excerpt of linker command file that is used showing anything that seemed pertinent to this issue.

MSP430F5310 using compiler 4.2.2
This places the entry point at 0x8000 because of following entry in the linker command file:
.boot > 0x8000
{
-l rts*.lib<boot.obj > (.text)
}

MSP430F5310 using compiler 16.9.1 LTS
Using compiler 16.9.1 LTS, this DOES NOT place the entry point at 0x8000 because of following entry in the linker command file:
.boot > 0x8000
{
-l rts*.lib<boot.obj > (.text)
}
With compiler 4.2.2, this DID place the entry point at 0x8000. It is broken with the new compiler.
