Hi,

I need to store a constant variable in external flash memory of my LPC1788 development board.

Any suggestion? sample project??? (BTW I'm using Keil uvision)

Hi hamidzz,
LPC1788 external static memory starts from 0x8000 0000. If you want to place a constant DataStream array of size 3 at 0x8000 0000 you can do it as shown below.

const uint8_t __attribute__ ((at (0x80000000))) DataStream[3]={0x1,0x2,0x3};

Hi MC

thank you so much for your informative reply.
Now, using your guidance, I realized that I need to define programming algorithm for my external flash device for Keil uvision (my ext. flash is k9f1g08u0c )

I know that it should no longer relate to LPC forum, but could you help me how to write the programming functions for that???
(I know there are guidelines to do so on keil website, but I little confused as I'm newbie ... ;)

Thanks again
