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

Raj Mittal

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.
