CCS V5.1 Memory Problem

Peter Selig
Prodigy 50 points


Hallo,

I've installed CCS v5.1 because I need an Eclipse version >3.5 to use the Perforce-Plugin.

My project for a F28016 works fine on CCS v4.
During the built with v5.1, I get several errors regarding the placement of the sections defined in "DSP280x_Headers_nonBIOS.cmd".

Available ranges:
RAMM0 size: 0x400 unused: 0x0 max hole: 0x0
BOOT_RSVD size: 0x80 unused: 0x80 max hole: 0x80
RAMM1 size: 0x380 unused: 0x84 max hole: 0x80
error: run placement fails for object "DevEmuRegsFile", size 0xd0 (page 1).
Available ranges:
RAMM0 size: 0x400 unused: 0x0 max hole: 0x0
BOOT_RSVD size: 0x80 unused: 0x80 max hole: 0x80
RAMM1 size: 0x380 unused: 0x84 max hole: 0x80
error: run placement fails for object "ECanbMOTORegsFile", size 0x40 (page 1).

 

 

CCS v4 places the objects starting with adress 0x880:

--- MAP-File ---

DevEmuRegsFile
*          1    00000880    000000d0     UNINITIALIZED
                  00000880    000000d0     DSP280x_GlobalVariableDefs.obj (DevEmuRegsFile)

FlashRegsFile
*          1    00000a80    00000008     UNINITIALIZED
                  00000a80    00000008     DSP280x_GlobalVariableDefs.obj (FlashRegsFile)

 

CCS v5.1 can't allocate the objects:

--- MAP-File ---

DevEmuRegsFile
*          0    00000000    000000d0     FAILED TO ALLOCATE
PieVectTableFile
*          0    00000000    00000100     FAILED TO ALLOCATE

 

The cmd - files are the same in both cases.

Can anybody help? Was there a change in v5.1 linker or what can be the reason for the problem?

Thanks in advance!

Best regards,
Peter

    Peter,

    Currently the linkers are very similar between 4.2.1 and 5.1.  My 4.2.1 install as the 5.2.6 compile tools and my 5.1 M1 install has 5.2.9 compile tools.  I wonder if something else is getting included that is messing up the allocation.  If you look at the build properties are any extra libraries getting pulled in?

    John,

    thank you for the hint.

    I have changed the .cmd file for the linker and have added a flash memory block of 1kByte to Page 1.
    Now the sections are located in this flash memory area and the linker works without error.

    I don't really understand why the objects can be linked into flash memory, but it seems to be OK.

    Best regards,
    Peter
