Hi everybody, Does anyone know how to load a lookup table (size-4K) onto the flash of TMS320F2810 DSP. I would like to store a file containing FIR filter coeeficients into the flash memory of the DSP. This need not be done at run time. Regards, byju

If so, the easiest way is to just build it into the program image, and program it along with the program as a single image. Or are you asking how to program the flash in general? There is no way to externally program the flash on the TI 28xx series. Only code running from internal RAM can do that. If you are using TI's Code Composer Studio, you can download a flash programming utility from their web site. You install it and it puts an extra button on the tool bar in the IDE, just click it to call up the flash programming utility. If you are using somebody else's programming tools or JTAG debugger, talk to the tool vendor or check TI's tech support. -- Jack Klein Home: http://JK-Technology.Com FAQs for comp.lang.c http://www.eskimo.com/~scs/C-faq/top.html comp.lang.c++ http://www.parashift.com/c++-faq-lite/ alt.comp.lang.learn.c-c++ http://www.contrib.andrew.cmu.edu/~ajo/docs/FAQ-acllc.html

Dear Jack Klein, Thank you very much.. I would like to put the data file containing the FIR filter coefficients into the flash.. how will I build the data file into the program image.. It will be easy for me if I could program this along with my program (C code) as a single image.. could you please tell me how can I combine these two? how I should change my linker command file? is it possible to build a data file along with my program file? Expecting your reply... Thanks Byju
