5.2.3 Serial Flash Memory Use
The RCM4300 module has a serial flash memory that contains the user block and stores
the application program. Two function calls are provided to work with the serial boot
flash. These function calls are in the Dynamic C LIB\Rabbit4000\BIOSLIB\
BOOTDEV_SFLASH.LIB
library.
sbfRead
sbfRead(void *dest, unsigned long offset, unsigned nbytes);
DESCRIPTION
Reads up to 64K from anywhere on the serial boot flash. This function call supports
both the blocking mode for use with C/OS-II and a mutex for preemptive multitask-
ing, and the nonblocking mode for cooperative multitasking. See the description for
sbfWriteFlash()
for more information on using a C/OS-II and a mutex with the
serial flash driver.
PARAMETERS
dest
pointer to the 16-bit address of the destination buffer
offset
the physical offset into the serial flash
nbytes
the number of bytes to read
RETURN VALUE
0 if successful.
The return values below apply only if _SPI_USE_UCOS_MUTEX is not #defined:
positive N to indicate that the SPI port is being used by device n
if more than _SPI_MAXTIME milliseconds elapse while waiting for the SPI port to become
available, one of the following two runtime errors will occur: ERR_SPI_MUTEX_ERROR
(when using C/OS-II) or -ETIME (if not using C/OS-II).
