Hi, we need to load code into an ADSP-21489 EZ LITE demo board for audio testing. What sw/hw do we need for this? Some kind of JTAG device? The code is coming from a consulting engineer/programmer, and we have never used this demo board. Thanks.
As mentioned by Al, you have 2 software options available to you. You can work with either CrossCore Embedded Studio (CCES), or VisualDSP++. Both are considered separate products and therefore licensing is is very different. For detailed information on licensing I recommend you read though the following documents:
VisualDSP++ Licensing Guide
CrossCore Software Licensing Guide
As your code is being supplied by a third party we'd recommend finding out what tools the software was developed with and use the same.
We sell 2 different flavors of 21489 boards, the 21489 EZ Board and the 21489 EZ-Kit. The EZ-Board package simply contains a 21489 target board. If you purchase this you'll require an external emulator to connect to it. The EZ-Kit package includes the same 21489 target board, but also comes with a Stand Alone Debug Agent (SADA-II) board. The SADA board allows you to connect to the board via USB without the requirement for an external emulator. However, one thing to keep in mind is the SADA offers the slowest connection speed and it's only compatible with our target boards. You will be unable to use this with a custom board.
There are several external emulators we have in production that are compatible with the 21489, these are:
Please click on the links above to find out more about each of these emulators.
You probably have a debug agent as part of your EZKit. This is a plug in module that acts like an ICE. It uses JTAG.
As long as you have the debug agent, you can use a Visual DSP++ KIt license which is free. It is limited after 90 days to program sthat uses no more than 1/4 of the internal memory of the DSP. I think this is about 27,000 instructions so this may not be an issue for your program.
You can determine this with your initial VDSP installation which acts like a full license for the first 90 days.
It is also possible that the developer used Cross Core Embedded Studio. If this is the case, you will need to purchase CCES after 90 days. The code base will be a little different than VDSP, so you will want to check with the developer.
If you don't have a debug agent, you can also use an ADI ICE. This will require a full license after 90 days.
Xlnt replies! Thanks to both.
I'm a bit confused -- are you saying that we need to buy a $5,000 license simply to load code into the DSP after the 90-day grace period? Our programmer is using the Cross Core system for coding. But we simply want to load his code into the DSP. We won't be doing any programming here.
CCES is not $5000.
If your need is production programming the flash, then the best tool is our dspFlash programmer. This is exactly what it is intended for. It does not use either VDSP or CCES. It comes with a Windows program. If you are going to do code development or modifications, you are going to want CCES & and an ADI ICE. In the USA, this is $1145 assuming an ICE-1000. This should be adequate for your situation.

We support the ADSP-21489 and many different flash devices including the type used on the EZ-Kit.
