Please help, CCSV4 Target Configuration for TMS320DM6467T using Spectrum Digital XDS510 USB

Helmut,

Now, I have a PCB from the same manufacturing run, but it's stuffed with a TMS320DM6467TZUTD1.  I've changed the outboard power supply from 1.2V to 1.3V as I should.  I've also removed the 33MHz crystal and connected the same jumper as appears on the EVM, to route the CDCE949 clock's 27MHz signal into the core instead.

I am pretty sure the change in devices will impact any initialization routine. Either if you are doing this programatically or via GEL files, I strongly suggest you checking the GEL files for both DM6467 EVMs at Spectrum Digital support webpage:

I can connect to the target.  However, when I load the program, upon completion of the load the ARM thread status is "Running", not "Suspended".  I'm stuck right at this point.

That is an indication that the device initialization may not be happening correctly. To further investigate this, can you disable the autorun to main (check here).

Looking closer, I wonder if the target configuration is the correct one.  I notice that the "EVMDM6467" does not end with a "T".  I can not find ANY option in the General Setup for target Configuration that ends with a "T.  Is this my problem, or is my problem something else?

From an emulation/debugger perspective the devices are the same, therefore the target configuration is the same.  

Helmut Forren said:

Is this higher current and temperature situation simply a fact of life for the DM6467T vs the DM6467, or is this also indicative of a problem?

The two devices share the same silicon process technology (90nm / Cu), therefore a clock scale is followed by an increase in temperature and current. I would, however, send the details to the device forum so you can get more knowledgeable guesses there. 

Hope this helps,

Rafael,

Thanks very much for the suggestions.  I'll research the links you provided.  

Before that, for right now however, it seems your advice is contradictory.  You said "From an emulation/debugger perspective the devices are the same, therefore the target configuration is the same".  Yet you suggest "checking the GEL files for both DM6467 EVMs".  Am I missing something? 

Maybe what I'm missing is a nuance between target configuration and gel files.  I'm slow on gel files.  I'm only using what came with.  I though the gel files came with the configuration.  Are you saying the configs may be the same but the gel files different?  (The gel file stuff is very OBTUSE!)

Thanks again,

Helmut

I'm using CCSV4.  I can't figure out how to see or do ANYTHING directly with GEL files.  The word GEL does not exist in any of the menus.  The help documentation has bad links for GEL details.  It's NOT at Tools / GEL...

Please tell me or remind me where to access GEL files, load them, select them, or maintain them, from within CCSV4.  A link to some valid doc would be very nice as well!

Thanks very much,

Helmut

Hi Helmut,

GEL Documentation can be found in the included Help files ('Help->Help Contents'):

See this wiki topic: http://processors.wiki.ti.com/index.php/GEL

Thanks

Another good GEL doc on how they are used to auto-initialize a target when starting the debugger.

Thanks.  Neither search nor index revealed this help location, and contents navigation didn't show the word GEL at the end of the long line in a narrower window!  And I didn't notice the spelled out General Extension Language.

FYI, the "GEL Files" option does not appear on the Tools menu at all, not even grayed out, unless your target configuration is currently launched.

I got to first base once, but not again...

My target config was already launched.  I loaded the GEL file, which came from Spectrum Digital as a newer version than the one I already had on disk.  I connected to ARM and DSP targets.  With the ARM selected, I Tools / Load Program the "nand_flash_writer.out".  This time, lo and behold, after the load the status was "Suspended" as it should be.  I then ran the program and I believe successfully wrote UBL to NAND.

So then I tried right after that to write U-Boot to NAND, but had no luck.  Note I never literally "RAN" the GEL file.  I just loaded it and later connected and loaded program.  Does CCSv4 know to use this GEL I loaded rather than one that came with the config?

Anyway, I exited CCSv4, unplugged the XDS510USB, and powered off my target, to retry.  Loaded CCSv4. Plugged in the XDS510USB usb cable.  Launched my target configuration.  Tools / GEL files then loaded my GEL file.  Finally powered on target last, to avoid overheating.  Connected to ARM.  Connected to DSP.  On ARM, loaded program.  "Running" status.  Still not working.

Am I having hardware trouble still, cold or hot?  Or am I not getting the GEL file in properly, except for the first time?

Thanks very much,

Helmut

Filename snafu, but still doesn't work.  Figured out GEL file view changes as you point to different devices in debug window.  But still having errors, even with correct GEL file.
