1 - I have to optimize my software in order to put all what I want on the DSP.
It is difficult because I have to adapt a soft A from PC to DSP and add a soft B
to command DSP. But even if the A algorithm is very large it is smaller than
command part (in memory), is it normal ?
2 - I wanted to know if is it better to let some part of RAM free to have a soft in good health ?
Something like keeping 10% of RAM free is sufficient, too big or completly unuseful ?
3 - Is it possible to modify the Mapping file like what I want ? Because the basic file haS a part of FLASH of
118o whereas the DSP has 256Ko, is it allowed to modify it if I keep on limits (I am wondering that because it
is really a high jump from 118o to 256Ko, is it normal ? I give you my memory map file...
4 - I put the .stack on the PAGE 1 (data) in RAMM1. But before to do this
I tested with an oscilloscope what are the signal in output and I observe something
what I can explain, could somebody help me ?
First : I put .stack in the RAML0L1L2L3L4L5L6L7 in page 0 (program) with the others things
and if I run the debugger it works, if I stop the debbugger it still working
because the oscilloscope show me signals which are changing like when the debbugger run
Secondly : I put .stack in RAMM1 in page 1 (data), when I run the debbugger it works, but when I stop
the debugger, nothing work on the DSP because no signal are changing on the oscilloscope
What is the reason ? What is the best?
5 - I am actually working via the debugger of CCS, but when I decide to let the soft on my DSP
for ever (I mean whitout PC it still working when voltage arrives) what I have to do ?
Nothing or more ? In fact I want to know if I have to put something in FLASH or if
something in my RAM file is needing or it is just sufficient to debug and run on CCS,
(Have I to put manually in flash or is it automatic? Have I to put the binary in ROM ? How can I do this ? Is it
done automatically?)
I am sorry for all my questions, but I think I need some help to understand what I am doing on
a specific card. Thank you to read me and to help me.
