Compiler/MSP432E411Y: How to work with pointer to fields of packed structures

Sven Probst

Part Number: MSP432E411Y

Tool/software: TI C/C++ Compiler

Dear Experts,

I want to make functions able to work on fields of packed structures. According to SPNU151U it is only allowed to create uint8_t pointers on such fields. This is not very handy and error prone, because it disables type checks by the compiler.

According to

https://developer.arm.com/docs/dui0472/e/compiler-coding-practices/unaligned-pointers-in-c-and-c-code

there seems to be support for this case in the arm compiler. Is something similar available for the TI arm compiler?

Hello George,

thank you for the clear answer. Do you have any ideas how to workaround the issue?

Is TI going to add such an attribute?

The best solution is the one you already mention, which is to use a pointer to uint8_t.

Unfortunately, there are no plans to add such an attribute.

Thanks and regards,
