Can any one tell from which address (in Flash)the booting starts in embedded systems .
Don't be surprised at the lack of replies to your question. You need to be much more specific if you want people to come up with reasonable answers: - Which processor are you referring to? - To me, the term "booting" implies that an OS is involved; please specify which OS you have in mind.
One more thing comes to mind: Maybe you are not referring to an embedded system running an operating system, but to a system with a boot loader. Please clarify.
it is a generic question , you can take ATEB9200 board to answer . I wanted to know when i switch on a ARM based SBC .. from what address booting process initiates like for eg. Boot rom in chip will load the bootloader from ____________address in flash. Is this address fixed ? , how it is pre-configured?
You have to read the data-sheet/manual of the microcontroller. Some chips have external pins to set the start-address and/or remapping, some have non-volatile-settings to configure the start address. So the question can not be answered in general. Most "small" SOC with internal flash I know start from address 0.

It's like asking "what is the voltage of most batteries?". There could be a good answer to that question if it was a little more specific.

Next time you'd do better to read the data sheet and/or user manual for
the device you intend to use.
