Msgbox when flashing Piccolo

Other Parts Discussed in Thread: TMS320F28027

I'm working with CCS 3.3 (3.3.82.13) and the Piccolo controller TMS320F28027 without DSP/BIOS.

When i'm starting the flash utility, it allways shows the Message: "The code Security Password Locations (0x33FFF8 .. 0x33FFFF)  have been added to the memory map." Is there something wrong with my .cmd Files?

    Christoph,

    What has me puzzled is those locations are not where the password is for the 28027 - it applies more for a 2833x device.  Are you sure you are using a 28027?

    The error means that the CCS defined memory map doesn't have the locations defined and the flash programmer needs to check them.  The  CCS memory map is defined by a GEL file that is loaded as part of the configuration.  It tells CCS what memory is valid on the device.   TI supplies a gel file for each processor. 

    Here is some information on GEL files - unfortunatly it is slanted towards CCS 4 but it may help:

    Dear Lori,

    thank you for quick answering my question. I use the Signum JTAGJet-C2000 Emulator and used a configuration for F2808 because it worked and there was no other chance.

    Due to your hint i created a new Board configuration similar to the F2808 but with the gel-File for F28027. The MsgBox still appeares when starting the Flash-Tool.

    I was also confused by the adress Range, because i found nothing in the Datasheet.
