Hi,

I have doubt regaring the SDRAM Intilization by processor.

How SDRAM and ROM will be initilized by Processor as boot code is there in the Flash.Does All processor have inbuild ROM for the Basic Boot of Processor?

What kind of Logic or the intelligence does processor have for Initilization of ROM and SDRAM interface before getting the Bootcode from Flash.

Regards

Memory Initialization can be summarized as follows:
1. Memory Controllers Setting
2. Copying RW Data to SDRAM
3. Copying RO Data and Code to ROM
4. Initializing Stack
