This option is available only when running from external SRAM
|
|
(CONFIG_BOOT_RUNFROMEXTSRAM). In that case there are two possible
|
|
options: (1) The configuration runs entirely out of SRAM and must
|
|
be copied into SRAM by a boot loader. Or (2) The configuration
|
|
boots out of FLASH, copies itself to SRAM, and runs from SRAM. This
|
|
configuration setting selects that latter option.

This is the size of the partition at the beginning to the W25

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