sf_writeDeviceRAM

int sf_writeDeviceRAM( sf_device * dev, long buffer, int offset, int len, int flags );

Description

Write data to the RAM buffer on the serial flash chip from a buffer in xmem.

Parameter

dev

Pointer to sf_device struct for initialized flash device.

buffer

Pointer to xmem data to write into the flash chip RAM.

offset

The address in the serial flash RAM to start writing at.

len

The number of bytes to write.

flags

Can be one of the following:

• SF_BITSREVERSED - Allows the data to be written to the flash in reverse bit order. This improves speed, and works fine as long as the data is read back out with this same flag.
  Ignored on R4000 based cores, but reserved for legacy code support.

• SF_RAMBANK1 (default) - Writes to the first RAM bank on the flash device

• SF_RAMBANK2 - Writes to the alternate RAM bank on the flash device

Return Value

 0: Success
-1: Error
