Naveena, DSPLink 1.60 has been released: https://www-a.ti.com/downloads/sds_support/targetcontent/link/link_1_60/index.html
You can use it in PROC-only configuration to load and start a non-DSPLink DSP executable.

Naveena, There is nothing of that sort currently available (as far as I know). You will need to refer to DSPLink HAL code to write it yourself for now.

So what is a possible way to run a non-DSPLink DSP executable from ARM? It will be more helpful if I get a sample program(firmware appln) or linux driver to do the same. Thanks, Naveena. ________________________________ From: Kamoolkar, Mugdha [mailto:[EMAIL PROTECTED] Sent: Friday, September 26, 2008 2:01 PM To: Naveena M.; [email protected] Subject: RE: To boot DSP and run DSP application from ARM. Naveena, Currently, no, this is not supported. While you can build in PROC-only mode, it still expects a DSPLink component on DSP-side, which will do handshake with the ARM-side driver to indicate completion of DSP start. This DSPLink component requires some shared memory. But DSPLink 1.60 (will be out before the end of October), will have support for this feature that you have mentioned. The PROC module can then be used in PROC-only mode, to load and start any non-DSPLink DSP executables also. Regards, Mugdha ________________________________ From: Naveena M.

If I am to use PROC section alone (to load and run)and no other communication mechanism (MSGQ, POOL ,CHL...), is there any dependency with memory configuration. ie. Is the DSPLINKMEM needed for PROC? Can I build the Dsplink driver with PROC alone?

Naveena, You can look into the hal (hardware abstraction layer) code within DSPLink sources as a reference for what you are attempting to do. It will have the right sequence of register settings.

I am not using the TI provided dsplink driver available with montavista. The TI provided driver supports API calls and those use to run DSP application from ARM are PROC_setup ,PROC_Attach ,PROC_Load and PROC_start. Now I am setting registers by running a firmware application and running on ARM side by connecting CCS using JTAG emulator. What I did was, loaded the dsp binary in the desired location from ARM application. Then I set the resest for DSP module by setting PSC_MDCTL for DSP. Then loaded DSPBOOTADDR with the starting address of the loaded code and took of the reset. The concept was, on reset, the DSP will start running from the reset address or DSPBOOTADDR. But the DSP code dint start running. Is there any other configuration that I have to look into or consider while doing this? Or What happens in PROC_start? Regards, Naveena
