TMS320F2812: Flash2812 Library code files.

Heather,

Sorry for the delay in replying, I need a bit more time to look into this in more detail.  As you said the .lib should be preserving the compile options for the flash API code itself.

Can you advise on what version of the compiler you are using in both the CCC3.3 and CCS12.3 compiles?  I believe we had a recommendation on this, but those are the facts I need to dig up.

Best,

Matthew

Matt, 

My CCS 12.3 compiler is 

  C2800 Compiler Tools 22.6.0.LTS

The original CCS3.3 only says, 

Code Generation Tools V4.1.3 

Thanks for the new info, I need to dig into the F281x support files a bit more to see what might be happening with the newer release.

Best,
Matthew

Heather,

If I set up a TI private cloud share drive would it be possible to share both the new and old projects with me?  I can't come up with a reason that the placement of the Flash functions would be impacted by the migration from CCS3.3 to CCS 12.3, especially since these are delivered as a library.

Let me know and I can send you a private link off forum to upload your projects and files.

Best,

Matthew

Matt, 

Please setup the private link

Matt, 

Also, let me know how you want the files, - just a simple ZIP of all the directories.. Or do you want a project export of some kind. 

Thank you for your assistance on this. 

Regards, 

Heather

Link sent, if you just want to ZIP up the files/directory that should be fine.

Heather,

More on the debug side, do you know if this is happening for any sector with the new compile?

Matt

I have only tried the first sector.  Since this code was already working once.. I didn't go into great detail trying to debug. 

Heather,

Sorry for the delay again. We will get back to you shortly. I am going to bring this up internally with other team members to see if we can help support you faster.

Heather,

I've done an initial check of the files, I'm going to see if some others have ideas.  I don't see anything obvious, other than the new tools shuffled things around in the memory; but references/function calls should be all relative.

For the boot28.asm file; is this your file or a TI generated file?  Can you give the path info, package info that this was a part of?  If this is a TI file, if you could add to the share drive that would be great.

Best,

Matthew

Also, did you look at the optimization settings in both the new and old projects and see if they were the same?  There looks to be code size improvement on the newer .map file; but there is also some re-arranging of where things are located as well.  Wondering if we can make the opt settings the same what we see.

Also, when you built the project, did you do a "rebuild all" vs "build"?

Best,

Matthew

So I see this in our compiler tools directory.  Can you send the older boot.asm from the CCSV3 install when you get a chance?

Matt

Sorry for my delays..  To answer your questions: When I build I do a Clean All and then a Build..  As for optimization I sent you the Debug verison of the code which shows Optimization level as off.  (see below)  It does show the speed vs size as a (2) but did didn't think that was doing anything with the Optimization level set to off.  Was I incorrect about that? 

I found the boot.asm file in the oldCCS3.3 here for reference. C:\CCStudio_v3.3\bios_5_31_02\xdctools\packages\ti\targets\rts2800

I will put the file in the fileshare.
