    Slow spi flash write

    pseguy

      Hello

       

      Whatever bloc size (1, 2, 4, 8Ko) I try to write to the spi flash (sflash_write), I get a constant very slow throughput: 13 seconds for each KiB written.

       

      Having a look at spi_flash.c make me think that low level writes are done one byte at a time.

       

      Any advice to increase write throughput would be appreciated.

      Thanks in advance,

      Pascal
