Hi,
I could migrate my project from CCS3.3 to CCS5.1.
The compilation is fine. The debug works fine.
But when I load the rom version the program just hang.
After verification I found out that the map file is different from what I have on CCS3.3
ENTRY POINT SYMBOL: "_c_int00" address: 003f8e64 on CCS3.3
and ENTRY POINT SYMBOL: "_c_int00" address: 003f8e65 on CCS5.1
I guess this is the cause because my program after the bootloader has started jumps to the application and does not just find the program at the right address.
Do you have any hint for this to help me.

Keli,
The entry point is usually highly dependent on the linker command file and the compiler you are using, therefore I will move this post to the compiler forum so the experts there can give a better assessment on this.
In the meantime, could you send the compiler version used in both versions of CCS? Also, could you take a careful look in the build outputs of both 3.3 and 5.1? That would help see if the differences are coming from any compiler or linker option.
Regards,
Rafael
Are you using ARM? Note that ARM EABI requires symbols for thumb-state functions to have their LSB set to 1 to indicate that they are thumb-state functions. Is this what is going on?
Hi Rafael,
Thank you for taking action in order to help me.
The compilers are:
CCS3.3:5. 5.2.11
CCS5.1: 6.0.2
The bios version are
CCS3.3:bios_5_41_09_34
CCS5.1:bios_5_41_11_38
