Hi ALL,

I have various question regarding ARM programming

* There is ARM is a HARVARD architecture, i mean the code and data had separate BUS?

* I have freescale IMX21 chip, its an ARM with lots of peripheral, i want to begin to experiment on it, say i just build simple blink led, and serial stuff, i connected flash and SDRAM on that chip, it is just simple like that way? i mean how to programming the flash (uploading my code)

*i hear some issue, run on RAM and run on ROM, can anybody assist me, i need fully working reference project to build an ARM project with external flash memory and SDRAM.

thanks

as i remembered there are some sample projects(led blinking/using UART) on freescale site. which are codewarrier projects.

first go through the those sample projects. project contains some hardwares setting before run your code . use those code as the template and develop your code.

using habtool you will able to download your program to the board. (if u r using mx21 ads board)

there different coding depend on whether your pro run on the ram or on the flash. burning Ram program on the flash wont work.

GOOD LUCK! :D

The ARM7TDMI has a von Neumann architecture. The new ARM Cortex-M3 has a Harvard architecture, it has a separate instruction bus and data bus.
