Some years ago Johnson Jiao & Raven Xue, then of Analog Devices, came up with a pure software approach to serial load an ADuC702x without requiring the ADuC702x serial load process to be initiated by the ADuC702x BM* and RST* I/O lines toggling LOW in a special boot sequence. Their recommended software approach is summarized in an Analog Devices web site document, ADuC702x_IAP.PDF or ADuC702x_IAP.PDF (please see attached).
The approach they recommend requires the user to duplicate the program load code of the already present Factory Configured Boot-Loader located as hidden code at 0x0008F800 to 0x0008FFFF.
My question is:
Instead of duplicating the already present factory configured boot loader is there enough information available about the boot loader that we could use the Jiao/Xue recommended software initiation of the boot-load process and then branch to the Factory Configured Boot-Loader?
All feedback appreciated.
