DESCRIPTION
PARAMETERS
RETURN VALUE
RabbitCore RCM4300 User’s Manual
int sbfWriteFlash(unsigned long flashDst, void* Src,
unsigned len);
Writes len bytes (up to 64K) to physical address flashDst from Src.
Keep calling sbfWriteFlash() until it returns zeroa or a negative error code. A
positive return value indicates that the serial flash SPI port is being used by another
device. If you are using µC/OS-II and _SPI_USE_UCOS_MUTEX is #defined, you
may call sbfWriteFlash()just once. If more than _SPI_MAXTIME milliseconds
elapse while waiting for the SPI port to become available, one of the following two run-
time errors will occur: ERR_SPI_MUTEX_ERROR (when using µC/OS-II) or -ETIME
(if not using µC/OS-II).
NOTE: This function call is not power-fail safe. The writeUserBlock() function
flashDst
Src
len
0 if successful.
-1 if an attempt was made to write to the user/ID block or program area.
The return values below apply only if _SPI_USE_UCOS_MUTEX is not #defined:
call provides a safer way to store critical data using redundant copies.
-EBUSY
positive
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 µC/OS-II) or -ETIME (if not using µC/OS-II).
