Target Firmware Setup

Connect the ethernet port of the Intel XScale
®
microarchitecture CRB to the server secondary
ethernet controller via a crossover cable or connect them both to a GbE hub. Connect the serial port
of the CRB to the serial port of the server. Running “minicom” should allow viewing of the
RedBoot console output from the board.
Ensure that the latest RedBoot is installed on the CRB. Currently the 20050321 IOP RedBoot
release is the latest and binaries are available from
http://developer.intel.com/design/iio/devkits/
softwaresupport.htm .
Should the board not have a valid RedBoot image installed, consult the board documentation for
instructions on Flashing via FRU or JTAG.
Assuming the board has a bootable RedBoot image installed, an update can be done via commands
from RedBoot. Parameters in the instructions below will vary from board to board.
Table 1 gives
the values for each of the SCD CRBs.
To download via XModem:
RedBoot> load -m xmodem
Note:
RedBoot> fis unlock -f {flash-addr-ram-img} -l {img_len}
RedBoot> fis create RedBoot[backup] -f {flash-addr-ram-img}
-b {ram-addr-ram-img} -r {ram-addr-ram-img} -l {img_len}
RedBoot> fis lock -f {flash-addr-ram-img} -l {img_len}
RedBoot> fis load RedBoot[backup]
RedBoot> go
RedBoot> load -m xmodem -b {ram-addr-rom-img}
Note:
RedBoot> fis unlock -f {flash-addr-rom-img} -l {img_len}
RedBoot> fis create RedBoot -f {flash-addr-rom-img}
-b {ram-addr-rom-img} -l {img_len} -s {img_len}
RedBoot> fis lock -f {flash-addr-rom-img} -l {img_len}
RedBoot> reset
