TMS320F280039: Modifications to int16_t and uint16_t type in C2000-CGT-v22.6.3

Part Number: TMS320F280039
Other Parts Discussed in Thread: C2000WARE

C2000ware version:6.00.01

In my project, I used both bitfield and driverlib, and referenced their header files using relative paths, as shown below:

I found that when I upgraded the compiler version from 22.6.2 to 22.6.3, the project that could compile normally before started to have compilation errors.

8 errors detected in the compilation of "../Sources/device.c".
gmake: *** [Sources/device.obj] Error 1

This is because in version 22.6.3, the definitions of uint16_t were changed from unsigned int to unsigned short. However, in C2000ware, the definition of Uint16 is still unsigned int. Therefore, my project throws an error when compiling source files with the following header file.

While int and short are equivalent in C2000, the compiler considers them to be of different types and reports errors.

    I observed the same issue with new compiler v22.6.3 in 28388D

    Thank you for notifying us of this issue.  I am able to reproduce the same behavior.  I filed EXT_EP-13044 to have it investigated.  You are welcome to follow it with that link.

    Thanks and regards,

    -George

    The _types.h file in the following path also has the same problem.

    #else
    typedef short __int16_t;
    typedef unsigned short __uint16_t;
    typedef long __int32_t;
    typedef unsigned long __uint32_t;

    After upgrading the compiler version to 22.6.3, an error occurred.

    Above issue was a result of the fix for https://sir.ext.ti.com/jira/browse/EXT_EP-12834 
    An updated fix for EXT_EP-12834 will be made and can be tracked with EXT_EP-13044

    In the meantime, for 22.6.3.LTS and 25.11.0.LTS, below workarounds can be used:
    Use only consistent type definitions from stdint.h

    Or undo below fix from EXT_EP-12834 in include/machine/_types.h
    and then rebuild the RTS library using mklib.exe per spru514 user guide.
    #else
    typedef short __int16_t;
    typedef unsigned short __uint16_t;
    To instead have this:
    #else
    typedef int __int16_t;
    typedef unsigned int __uint16_t;
