Tool/software:

Hi experts,

I need build "boot_ex1_cpu1_secure_flash_cpu1" project in COFF format.

I change the output format to CPFF format

Changed the support to FPU32

Rebuild the "drivelib.lib" in COFF format. And add the lib from C:\ti\c2000\C2000Ware_5_03_00_00\libraries\boot_rom\f28P65x\rev0\rom_symbol_libs\cpu1\SafeZoneCode_coff

However, I meet the issue when building.

Any suggestions for this issue?

Thanks,

Leo

Hi Leo,

F28P65x bootrom functions have been compiled with EABI. Linking failed since the COFF build did not recognize the EABI symbol. Only way around this is to compile using EABI. Any particular reason reverting to COFF?

Best regards,

Joseph

Hi Joseph,

Got it. I am checking with customer to ask them change the project to EABI format.

BTW, do we have the manual about function name defined in the SafeZoneCode lib file?

Thanks,

Leo
