SM320F28335-HT: Possibility of F28335 flash library with EABI support

user3503326

Part Number: SM320F28335-HT
Other Parts Discussed in Thread: C2000WARE

Hi,

I'm porting a bootloader application to a SM320F28335-HT. I would like to use #pragma LOCATION as described in "TMS320C28x Optimizing C/C++ Compiler v18.12.0.LTS"/spru514r.pdf

To use this pragma i need to use the EABI output format (as described by "warning #1513-D: The location pragma requires EABI")

My problem is that the project writes to the flash, using Flash API v2.10, which is buildt with legacy COFF. Is it possible to get a EABI build of the library?

Best Regards,

Kjell Arne

Kjell,

There are currently no plans to migrate the Flash API to an EABI build.

An alternative to the #pragma LOCATION directive is to use the #pragma DATASECTION directive along with a complemetary section defined in the linker command file.

A guide to this usage is here (MSP430 based but still applicable) https://processors.wiki.ti.com/index.php/Placing_Variables_in_Specific_Memory_Location_-_MSP430#Using_DATA_SECTION_PRAGMA_With_Defined_Memory_Section_in_Linker_Command_File

A C2000 based code example that uses this directive can be found here http://dev.ti.com/tirex/explore/node?node=AP83sv1wzMxCRVbTwcfKJw__gYkahfz__LATEST for online tools.

For local C2000Ware install the path is: C:\ti\c2000\C2000Ware_2_00_00_03\device_support\f2833x\examples\adc_dma\

Best,

Matthew

Thanks for the clarification and the examples. It looks like a usable workaround, even though it is slighly more work.

Best regards
