RTA error when using CCS

Hi,

when I ran "dsplib_v210/example/fft_example.pjt"(http://focus.ti.com/docs/toolsw/folders/print/sprc265.html)  in CCS v3.3,  and then clicked one of RTA buttons on the menu bar. CCS told me:

------------------------------------------------------------------------- 

Your BIOS version is not compatible with this RTA version.
It must be version 5.2.x.x.
Your version looks to be: a non BIOS program, or possibly BIOS 490 or earlier.

-------------------------------------------------------------------------

I'm sure that my bios is v5.31.02, but I can not find any information about RTA version from help menu in CCS.

Could you tell me how to resolve it?

 

By the way, I thought it was an error in this example. Please look at the lnk.cmd file.

MEMORY {
   EXT_MEM     : origin = 0x80000000,  len = 0x8000000
   INT_MEM     :  origin = 0x10800000,  len = 0x8000
}

After checking memory map, I thought 0x10800000 should be 0x11800000 (L2 RAM in C64+). The memory area beginning with 0x10800000 is reserved.

Thanks.

    I am not too familiar with CCS or RTA, but hopefully someone can shed some light on this.

    With regards to INT_MEM definition, I do agree it does not look correct, but is there a reason you chose L2 as opposed to L1.  I probably would have chosen

    o = 00800000h   l = 00014000h

    But then again, CCS (e.g. linker command files) is not my strength areas, but I have seen other linker command files use the definition above for internal memory.

    The project (dsplib_v210/example/fft_example.pjt) doesn't use DSP-BIOS. You will notice there is no TCF file included in the pjt. Thus, if you try to use the RTA tools, you will get error. (Your version looks to be: a non BIOS program, or possibly BIOS 490 or earlier.)

    The memory map may differ from device to device. For ex, for the http://focus.ti.com/lit/ds/symlink/tms320dm6437.pdf the example memory map is fine.
