4-byte alignment for structures and arrays. (ARM-Cortex-M4F)

Refering to:

LP-XDS110: not able to connect - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E...

Part Number: LP-XDS110 Other Parts Discussed in Thread: UNIFLASH Tool/software: after installing new CCS12.8.1, i am not able to connect XDS110 with any target

I would like to ask what is the recommended method to 4-bytes align data structures (especially static data structures) specifically for TI ARM Compiler.

Also is there a mechanism to force the data structure to occupy a particular address?

    From looking at your other thread, I can tell you want to align an array of unsigned char.  There are two methods to consider.  One is the DATA_ALIGN pragma, documented in the TI compiler manual.  The other is the GCC attribute for aligned types documented here.

    Yes.  The LOCATION pragma and location attribute are discussed in the TI compiler manual.

    Thanks and regards,
