TMS320F28386D: Hex directive

Hi.

Please refer to section 12.4 - "ROMS Directive" and related sections of this document: https://www.ti.com/lit/ug/spru513w/spru513w.pdf 

The CMAC key needs to be stored in a flash location and needs to be 128-bit aligned.

-Kedar

I already read that document，but did not find how to realize the 128-bit aligned in the document.

I need help that how to make 128-bit aligned happen. Does it need special symbol written in the above cmd file？Do TI have the exmaple how to make it？

Please take a look at this : https://software-dl.ti.com/ccs/esd/documents/sdto_cgt_Linker-Command-File-Primer.html 

The section "Allocate an Input Section from a Library to Different Load and Run Addresses" has details of how the "ALIGN" keyword works.

-Kedar

Sorry, I checked the part, but still not get the wanted information to guide how to implement the 128-bit aligned

You need to use "ALIGN (8)". This will align the data in size of 8 words.

I tried before，but it resulted with build error.

Is the command placed in the CMD file? Can you please share your command file?

There are two cmd in the example project, boot_ex1_cpu1_cpu2_cm_secure_flash_cpu1

0363.CMD.zip

The "ALIGN" keyword is typically used in the SECTIONS part of the CMD file.

I also tried this way before, it aslo resulted with build error
