            Status: UNCONFIRMED

          Priority: low
         Component: SPI
        AssignedTo: unassigned@bugs.ecos.sourceware.org

Created an attachment (id=1087)
 --> (http://bugs.ecos.sourceware.org/attachment.cgi?id=1087)
patch for at91_spi.c

The at91_spi.c has a hal-delay in the dsr() which could be avoided. And in some
cases the spi_transfer dont work correct. If there is a byte aviable from an
old transfer in the SPI-read-register, then the spi-transfer-function stores
this in the new to receive buffer and lets the last byte of the current
transfer in the read-register. Its nessesary to clear the "data-aviable" flag
befor starting a transfer. patch attached...
