Description
Technical field
The present invention relates to SOC to start solution technique field, and in particular to a kind of SOC starting early stage is loaded into the side of user configuration
Method and system, Bootloader mirror image and its configuration method.
Background technique
Embedded SOC generally can be in one piece of ROM of Embedded, and ROM is upper to solidify one section of starting code, normally referred to as
ROM Code.After CPU solution resets, ROM Code can be first carried out, Rom Code is responsible for being loaded into from External memory equipment next
The starting code in stage, commonly referred to as Bootloader.
Since ROM Code has been cured inside SOC in the SOC flow piece stage, the later period can not be modified, so ROM Code
In order to support External memory equipment as much as possible, generally directed to bus interface configuration than more conservative, it will usually to total
Line timing reserves bigger allowance, and uses forms data line etc..But these means will lead to ROM Code from external storage
The speed of the loading Bootloader of equipment is slow, and optimum efficiency is not achieved in other words.
To solve the above-mentioned problems, in the prior art by increasing a module inside SOC, for specially being deposited from outside
It stores up and is loaded into equipment and is configured using these, discharge CPU later.But this mode is needed specially to design IP module and be deposited from outside
