Part Number: TMS320F28377S

Tool/software: TI C/C++ Compiler

Hi expert,

My customer developing F28377s with TI v18.12.1.LTS. They put user bootloader and app in one project, they have shared RTS library functions located in bootloader flash sector. Problems occurs when they changed code in app part, then they find contents of RTS library changed in some bytes which makes no sense. Could you help me find out the reason behind?

Their CMD file:

MAP file:

Below picture shows changes in firmware of RTS library:

Thanks!

  • The RTS code refers to some global data variables.  It is possible the addresses of those variables changed, which would result in changes in the encoding of instructions for that RTS code.  Please compare the similar .out files with the utility objdiff from the cg_xml package.  Use the --verbose option.  Capture the result in a text file.  I also need the map files from each build.  Please zip all that up and attach it to your next post.

    Thanks and regards,
