U-Boot is controlled via a serial connection. The default setting is 56700
baud, 8 data bits, No parity, 1 stop bit. See
page 2-25 for information on the serial connector.

SPI flash can be modified. For instructions, refer to the VisualDSP++
online Help, example program included in the EZ-Board installation
directory, and U-Boot documentation. U-Boot includes an SPI flash
driver and can be used to download a new file over Ethernet or serial con-
nection, and write the file to SPI flash.
By default, the EZ-Board boots from the 16-bit flash parallel memory. SPI
flash can be selected as the boot source by setting the boot mode select
switch ( ) to position 3. See
