CCS/MSP432P401M: Software BSL invocation from C++

Zoltan Lencses

Part Number: MSP432P401M

Tool/software: Code Composer Studio

Hi Everybody!

I'm using MSP432P401M devices in our own HW. The software is written in C++ with CCSv9.

To update the software of the device I want to use the software BSL invocation method. I've copied the code from SLAU622H Chapter 3.3.1, but the compiler drops the following error message: "#141 too many arguments in function call" at the line "((void (*)())BSL_ENTRY_FUNCTION)((uint32_t)BSL_PARAM); // Call the BSL with given BSL parameters".

Same error message if I use the "BSL_INVOKE(x)" macro from file "msp432p401m.h" file.

If I use the same code in a simple C project than everything is OK.

What is the solution for the C++ project?

Thanks,

Zoltan

Hi Adrian,

Unfortunatelly not yet! I can compile it in a C code only.

Hi Adrian,

Thank you for your help! This is a solution!

@TI, please modify the following in the documentation slau622i Chapter 3.3.1:

source code line "((void (*)())BSL_ENTRY_FUNCTION)((uint32_t)BSL_PARAM);" change to "((void (*)(uint32_t))BSL_ENTRY_FUNCTION)((uint32_t)BSL_PARAM);"

@TI, please modify in the Simplelink SDK the file "msp432p401m.h" (and all similar files of different CPUs):

line 6869:

current version --> wrong:

#define BSL_INVOKE(x) ((void (*)())BSL_ENTRY_FUNCTION)((uint32_t) x) /*!< Invoke the BSL with parameters */

OK version:

#define BSL_INVOKE(x) ((void (*)(uint32_t))BSL_ENTRY_FUNCTION)((uint32_t) x) /*!< Invoke the BSL with parameters */

Thanks,

Zoltan Lencses
