Abstract
This invention relates to an advanced system and method of reprogrammable boot codes and In Application Programming (IAP) of embedded systems by booting up with boot loader to shadow program codes on to an internal high speed SRAM and extending contiguously to external higher space memory for runtime applications, and supporting on-line IAP to update run-time firmware or boot loader driver through network communication by utilizing advanced address remapping scheme as well as supporting In System Programming (ISP) to program initial Flash memory via ISP adaptor.
