6711 DSK CCS 2.00 not support 67xx

Hi,

As Ki mentioned in this thread that you added a comment, CCSv2 is very old and unsupported and CCSv5 supports the C6711 device. Differently to what was mentioned at that thread, the parallel port emulator of your development board is unsupported (check this thread) and therefore you will have to use an external emulator (a XDS100 is our lowest cost emulator and does not require purchasing a CCS license; all the others do). Also, CCSv5 does not come with any bundled DSPLib software, thus requiring installing it separately (as you did with CCS 2 anyways).

I have a few comments:

First strange is, that product install just C6000 dsplib. C6700 dsplib not installed even if sale with 6711 DSK and 6711 DSK connected. Looks like 6700 (floating point) dsplib not in installation disk!

This is a matter of release dates. The SPRC121 was released years after CCSv2, therefore it was intended to work with the CCS release at that time (3.1 or 3.3). Also, this is probably the reason for the linker errors you got when trying to rebuild the library. You could try to download a newer release of compiler in the Update Advisor, which may be compatible with this library. However, I am not sure if the DSK version has this feature.

Considering all this, my idea to you is that you should try to use CCSv5.5, as it is more modern and supported. A few threads may help you overcome any integration problems (one is here).

Hope this helps,

Rafael

"this is probably the reason for the linker errors "

The error is invalid instruction for 62xx at assembler because -mv6700 option ignored.

"newer release of compiler in the Update Advisor"

DSK 6711 CCS (1 or 2) in not updatable (ti policy). 

Looks like only way to buy 6713 dsk, but by the webside delivered with "Code Composer Studio IDE, version 2.2", therefore it is not a solution.

I think the instructions to rebuild the library may not work when using the newer compiler, but even still the library could not be rebuilt when the -mv6700 option was explicitly passed to the mk6x command

In this case it seems the command properly recognized the floating point extensions of the C6700 DSP but the library code has an intrinsic problem, and therefore you may have better insights from the experts at the C6000 forum (we here at the CCS forum do not support the device-specific libraries).

If you are contemplating purchasing another development board, DSK6713 is fully supported by CCSv5.x - including the USB JTAG, which allows using it with the free bundled license. Also, a more modern floating point DSP is the TMS320C6748 - it has several development boards. Simply check its product page for these details.
