Hi all! has anyone of you worked with the C672x series, especially with DSP/BIOS? I have a 6727 and the latest version of DSP/BIOS but the problem is that the HWI module of bios doesn't have "interrupt source" pin selector! So how to declare an hardware interrupt on 6727 with DSP/BIOS(wich I need for other things like SWI)? For the moment, I declared my ISR functions using CSL...


C6424 Cache without BIOS

I have an application that is running on a C6424 using the BIOS. I have the same application running without the BIOS but it runs at about 1/8 the speed. I'm assuming this has to do with the cache setup. All the SECTIONS declarations are mapped to the DDR2 memory. Is there a "simple" way to configure the cache to get this application running at the speed it does using the BIOS (no BIOS fe...

Hi, This post is related to my post on cache without the BIOS in the C6424. I've got a working engineering demo (audio portion of an MPEG video encoder used for broadcast) of an application running well on the C6424 with the BIOS and McASP HWI using the BIOS. The McASP HWI's are using a lot of CPU cycles for the audio samples so off to using the EDMA3 I went. I've got the EDMA3 working w...

Has anyone in this group had any success getting HSRTDX to work within a DSP/BIOS program? I am using this BlackHawk USB emulator, and I can get all of the various sample RTDX applications to work in HSRTDX mode, so long as they utilize the CSL and _not_ DSP/BIOS. As soon as I switch over to DSP/BIOS, things don't work. If I take the DSP/BIOS application and switch over to regular RT

Hi, I am using CCS2.0 to develop software for C6713, and already installed CSL downloaded from TI.

It turned out that the C++ name mangling was the cause. It is easily overcome by adding a declaration at the top of the source file that contains the functions that are referenced in the DSP/BIOS configuration. extern "C" { void myfunc(); void myfunct1(); } This is described in the DSP/BIOS User Guide. We also found it necessary to have the Parser code generation switch for C++ enable...
