From: bharat pathak on 17 Mar 2010 07:38 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

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

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
