Hi,i m building a simple board for an audio application using C5509A.There
will also be a codec and voltage regulator on the board.I need to know how to
download the CCS code on the processor.What additional hardware is needed on the
board to download the CCS program onto the DSP?

You need a JTAG header.

I suggest you locate the DSK 5509 board schematic on TI's website and copy the
"external JTAG" circuit (note:  you
want the JTAG interface to external emulator, not the "embedded CCS JTAG
interface", which is Spectrum
Digital-proprietary and not allowed for your use).

The DSK 5509 board schematic might show other useful features you can implement
also.

Hi,

You need to have some kind of Flash memory chip to hold the code on the
board, which serves as a bootup memory location.
And if you need to program the flash memory with your code (may be for
development and debugging), you must have a JTAG emulator port and required
hardware. Otherwise, you can burn  the flash chip with your code, and place
it on the board.
With regards,

Hi,
     Thanks a lot for the replies.I think the JTAG headers are used when we are
using the JTAG emulators.And i cant afford an emulator because it is a final
year engg college project.So is using the flash memory option better?Can i flash
the code on the DSP C5509A first and then place it on the board?

Your Univ should have at least one JTAG emulator + "full" CCS version.
 If not, your Prof / Dept. chair can get a good
deal from TI.

It's definitely not a good idea to try to bring up a custom DSP board without
JTAG.  If you get stuck, not only will
you not be able to view memory, single-step code, and otherwise "see"
what's going on, but also there will be no peer
help.  Everyone will expect you to have JTAG, both peer groups and TI support.

For a serious hardware project, a few $$ is always required.  If your Univ
doesn't have that, they shouldn't be doing
DSP hardware.

As you have said it is a class project you are working and I assume that
it
is a development project. In that case going for a flash memory burnin
seperately is not a good option. It would be better if you can get the JTAG
emulator, for this purpose.

Jeff is right, Jyoti.  Besides, it doesn't cost anything to put  
traces on your board for the JTAG header, and then at least you'll be  
prepared in case you have to beg, borrow, or hack your own JTAG  
controller.

There is no Flash on the C5509A.  The only non-volatile memory is the  
ROM, which you cannot change.  If you loaded the code first, you'd  
have to find a way to keep the chip powered while placing it on the  
board, and I don't think that is possible.

The key is that the C55x series wants to load it's code from an  
external source.  You can either find a Flash memory chip to add to  
your board which has a package compatible with a socket, and program  
the external Flash chip before placing it on the board, or you could  
research the USB boot.  If you implement the USB interface for the  
C5509A successfully, then you can set certain pins on the C5509A so  
that it boots from USB.  You should look at the C5509A spec sheet,  
because there are a lot of options for the source of the boot code,  
and one of them might work for you.  e.g. some of the serial options  
might be easier than Flash or USB, depending upon your situation.

Hi Jioty,

TI emulators can be quite expensive for a uni project.... what about these?  

http://shop.ebay.co.uk/items/_W0QQ_nkwZJTAGQ20TIQ20DSPQQ_armrsZ1QQ_fromZR40QQ_md
oZ 
In our company we use one of them and it works perfectly.... if you need more
details on which one we are using I can  check it for you,

Kind regards,

Sergio

Hello,

In a project we finished 2 years ago, we slightly modified two of our 
C5510 DSK to use only the JTAG part to communicate with the PC, and our 
own DSP HW board.
Everybody was happy with this solution. The industrial partner had 
bought a JTAG emulator but at the end he preferred to use a modified DSK 
as well.
Unfortunately I cannot give your more details as the modification was 
done by a young colleague that is not here anymore and the industrial 
partner. It was a minor modification (cutting a couple of lines and 
soldering a cable) and at the end of the project they reverse it in few 
minutes.

I hope this help,

Sara
