Hi.

I'm trying to use 

'Boot from Embedded SRAM mode' in KEIL MDK.

Where can I find reference example of 'Boot from Embedded SRAM mode'  with STM32F103 ?

You probably won't 'find' an example, you should apply your knowledge of micro-processors and compilers/linkers to create one. Right now you're so far over your skis that you need to explain why this functionality is important for you to understand.

Perhaps there are some code example to boot STM32 by UART in the tool smt32flash.

This tool will boot SMT32 from SRAM after flash code

It's open-source,

http://stm32flash.sourceforge.net

from its help, The communication protocol used by ST bootloader is documented in following ST application notes

I can't understand why everybody wants to know what why I have this question, I want to ask you vice-versa.

After search, perhaps I got wrong because that tool is to boot STM32 from 'User Flash', 'boot from embedeed SRAM' is totally different thing. Please forget my post!
