DSP/BIOS running out of flash

Started by thegreat105 July 15, 2004

Hello All,

I am working on DSK C6711 board. To add the kernel features if I
configure my application using DSP/BIOS tools would it be possible to
run the same application out of flash. Moreover I want to know that
if I doesn't was to add profiling and analysis tools in my final
application to set up so that it must run out of flash, what things
need to be taken care and how can I do so.

Thanks,
Shazia



Hello Shazia,
 
I am pretty sure that it will not work.  I believe that the main issue is that the DSP/BIOS internal architecture [it is coded in assembly] assumes that it is running in r/w memory.  To put it in Flash would require segregation of code and data/storage memory [which would require a design change].
 
But what you can do is to have the DSP/BIOS load into RAM from Flash [instead of from CCS] and run.
 
Also, the 6711 DSK Flash interface is only 8 bits wide - I have run code from it and it is S-L-O-O-O-W!!
