TMS320F280049C: Can the program be divided into two parts, one is loaded into RAM and the other is loaded into Flash?

Hi Yale,

When some content is mapped to flash and some to RAM, CCS or any 3rd party tool does not guarantee loading the RAM content.

Flash plugin is developed for fully embedded flash applications.  Meaning, all of the initialized sections in linker cmd should be mapped to flash.  If anything needs to be executed from RAM, that content should be copied to RAM at runtime using memcpy() before executing that content.  Please see below FAQ for more info on this.

Thanks and regards,

The reason that our customer's usage like this is because he found below comment in 28004x_generic_ram_lnk.cmd at C:\ti\c2000\C2000Ware_4_01_00_00\device_support\f28004x\common\cmd:

What this comment exactly meaning?

Thanks & Regards
