Name
cyg_bundle_access_flash — Initialise “flash” bundle context
Synopsis
#include <cyg/bundle/bundle_api.h>
cyg_bundle_context_t *cyg_bundle_access_flash(const cyg_flashaddr_t bundle_addr, const cyg_flashaddr_t limit_addr);
Description
Initialises context for accessing non-memory-mapped flash based bundle
images via the standard eCos flash API. This “flash”
access mechanism is primarily for indirectly-accessed flash memory
(e.g. SPI devices), though nothing prohibits the use of the flash API
from accessing memory-mapped flash images. This functionality is only
available if CYGPKG_IO_FLASH is configured.
![[Note]](pix/note.png) | Note |
|---|---|
If the target flash memory is accessible as a readable memory-mapped area then it is highly recommended to use the “direct” access mechanism for performance and dynamic memory footprint reasons. |
Return value
Pointer to object or NULL if unable to create context.
