CCS/TMS320F28377S: Filling 0xFF instead of 0x00 while creating binary file

Is there a way to have 0xFF instead of 0x00 in the binary file generated for the unused area.

There is no command line option, or anything similar.  

However, ${CCE_INSTALL_ROOT}/utils/tiobj2bin/tiobj2bin.bat is a text batch file you can edit.  Here is how you can change it to make it fill unused areas with 16-bit words of 0xffff.  

First, make a copy into another file name.  For now, call it fill.bat.  Find this line ...

%hexcmd% -q -b -image -o %binfile% %hextmp% %outfile%

This line invokes the hex utility.  In your case, that's hex2000.  The -image option allows you to use the --fill option to specify a fill value.  So, change that line to ...

%hexcmd% -q -b -image --fill=0xffff -o %binfile% %hextmp% %outfile%

Now, use fill.bat instead of tiobj2bin.bat.  

Please note this solution has undergone only very minimal testing.  Test it thoroughly before using it.

For those who consider using this solution on some other device family than C2000 ...  The width of the --fill value needs to match the word width on your CPU.  C2000 is unusual in that word width is 16-bits.  It is usually 32-bits.

Thanks and regards,
