at25_main is a tiny program that runs in ISRAM. at25_main will
|
||||
enable SDRAM and configure the AT25 Serial FLASH. It will prompt
|
||||
and then load an Intel HEX program into SDRAM over the serial
|
||||
console. If the program is successfully loaded in SDRAM, at25_main
|
||||
will copy the program at the beginning of the AT26 Serial FLASH.
|
||||
If the jumpering is set correctly, the SAMA5D4 RomBOOT loader will
|
||||
then boot the program from the serial FLASH the next time that it
|
||||
reset.

This is the size of the partition at the beginning to the AT25

this program must run from SRAM, there would be no purpose int
