Other Parts Discussed in Thread: TMS320F2808

Hello,

I'm using a TMS320F2808 and i need to mamorize a variable in non volatile way. So i need a variable tha can be changed at runtime but not lost when the device is switched off.

I think i have to memorize the variable in flash, but in witch sector do i need to put the variable? is a variable value contained in one Flash sector changeble from the code written in another Flach section?

Thaks

    You can dedicate any sector for your data storage .. I don't think it matters. Please go through all flash program related documentation to understand the procedure. As far as I know you for C2000 devices you can't program a falsh sector from another flash sector. All flash programming routines need to run from RAM. Again, C2000 has related documentation as reference.
