Hello,
We have C6713 DSK from TI. Is it possible to store
paramters to flash memory (256 KB onboard) so that
i could retrive the same, when i run another program?
I am utilizing this board for speech recognition project
and want to store the speech templates generated during
training process. I wish to store those on flash, so that
they would not be erased when power goes off.
When i actually test using speech inputs, the template of
the speech input would then be compared with the stored
templates on the flash.
Please help.
Regards
Bharat
can the onboard flash be used to store parameters?

If this processor's flash works like others that I've used then it's not going to be the easiest thing in the world -- you generally can't read any of the flash if you're writing to it or erasing, which means you need to run the flash read/write routines out of RAM, and you can't do anything else. Ask on comp.arch.embedded -- this is really far more a generic embedded programming question than a DSP one, and the crew over there is a larger one than the regulars here. -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com

If there is a flash on the board, then there is a way to read and write it. Although writing to flash could be not so good idea, as the flash could contain bootloader which you don't want to erase by accident. VLV

Vladimir, Mind your language. You might know lot of things which does not qualify you to insult others. I too have good enough experience in DSP theory, modelling and implementations with vlsi perspective. But I am begineer using DSP boards. And remember all begineers will ask all kinds of questions. You may choose not to respond, if you do not like the level of the question being asked. Regards Bharat

Although writing to flash could be not so good idea, as the flash >could contain bootloader which you don't want to erase by accident.Actually, it is not so stupid as it seems. You yourself indicate that at least you must take care not to erase the bootloader. Likewise you must take care not to erase your own program. You have to use a processor that can erase flash in blocks. If the TI processor can't do that, at least Renesas can. (e.g.R16C). It had been better to sum up requirements first, then switching processors late in the game. I have done some work with Renesas in Forth and could do that in actual practice. That means, from my program I can erase part of the flash, then put something there. How the ubiquitous Visual Studio clones for c-programming hold up against such a task I don't know. It can be a challenge to find out how to do that even if there is a way. You have your work cut out for you. Click on each of the silly little drawings (icons) and look what happens. ;-) If you have invested heavily in the project already, and there is no internal flash, you may interface a flash from parallel I/O.
