2812

Arye,

That is a bit of a vague question. If it meets the requirements of the project, staying with F2812 will probably give the fastest path to complete the project as you can re-use the most code.  Alternatively, if you can fit the design in one of our Piccolo class devices, you can probably save some cost.  If you want a little more powerful device, look at F28335.  If you also need a host controller, look at Concerto devices for an all-in-one solution.  

Hello Devin:

I was concern about the 2812 dsp because it is an old device. Is TI corecting bugs that were found in the DSP ? Is TI planning to support it for a Long time?

I need a DSP with XINTF. Is the 28335 is the only DSP with XINTF.

Regards Arye

Arye,

I don't suspect that F2812 will get NRND status for quite awhile yet, but I will see what I can do to get confirmation (we will support it even after it becomes NRND).  We will not be performing additional revisions or bug fixes.  

For XINTF you want F2812 or F28335.  In addition to devices with XINTF, you may be able to use Concerto, which has a similar peripheral, the EMIF. 

Devin Thank you for the prompt response.

I have another question a while ago and did not receved an answer yet. May be you can answer?

I am working on Concerto F28M35H52c1 using F28M35xx Control Card and Code Composer version 5.3.0.00090. I want to use the EPI in Host Bus 16 bits mode (HB16).

I configured the registers based on your control suite HB8 example.

When I checked with the debugger the only registers that changes were: EPICFG, EPIBAUD, EPISDRAMCFG, EPIHB8CFG, EPIGPCFG.

The firsts two registers  (EPICFG=0x13, EPIBAUD=1) are the right registers, but the remained registers are wrong. They should be  EPIHB16CFG, EPIHB16CFG2, EPIADDRMAP.

On the other hand if I look in memory the offset of the registers are correct and the get the right value: EPIHB16CFG is in offset 0x10, EPIHB165CFG@ is in offset 0x14

and EPIADDRMAP is in offset 0x1C.

I tried also to change the actual registers on the EPI0 register display but I failed.

Can you confirm to me that this is an environment problem and not a real proble?

Regards and waiting for a fast response.

Arye,

I confirmed that there is no worry of F2812 NRND.  

Unfortunately, I do not know much about the Concerto EPI (you can tell because I called it the wrong thing in the above post :) )
