Re Help Required: How to use onchip flash to store variables?

Hi devlopers,

I am usign LPC 2138 ARM controller right now. It has only 32 Kb of SRAM, I have one array say
" char Table[300][300] " of approx. 100 Kb.

I want to store this table in on chip flash memory which is 512 Kb, can anyone guide me how to accomplish this task.

I am using Keil u vision3 compioler and MCB 2138 board [having LPC2138 controller], and using flash programming with LPC flash utility [COM].

Thanks in advance,
Saurabh Pandya

  • "How to read back from flash"

    ARM processors generally have continous memory map, Review the memory map of your controller. You can directly read data from flash locations [using some mean of pointers]

    Yes, IAP is real time. Its allows to read and write flash during program execution. And offcourse you can update your program ,using IAP that is firmware update. But I dont have much information about this.
