TMS320F28P550SJ: ALIGN(8)/ALIGN(4) in .cmd files

Part Number: TMS320F28P550SJ

Hi champs,

 

I am asking this for our customer.

The user uses TI SCI bootloader and flash API as the programmer for programming their codes.

Initially, the user did not add any ALIGN (4) or ALIGN (8) for sessions allocated to flash in the .cmd.

Then, the user found there would be something unexpected happening.

After adding ALIGN(8), then the user finds it works.

Now, they are trying to clarify the root cause.

Questions:

  1. Do we have any doc to explain why and how this ALIGN(8) or ALIGN(4) is needed in the .cmd files?

     2. How does ALIGN(8) or ALIGN(4) work?
