Note
Multiple Update Firmware
commands will generally
be required to transfer the
entire program image from
the host to the FCR200
DRAM. When the last data
block is transferred (mode
= 0x07) the FCR200
terminates data transfer
and performs a CRC
checksum on data
received.
It is required that the FC
initiator sends from the
beginning of the firmware
image to the end. No out of
sequence Write Buffers are
allowed.
If the CRC test is
successful, the Controller
will reboot. The FCR200
will use the newly updated
firmware. If the CRC test
fails, the image transferred
to DRAM is discarded, and
the controller continues to
use the previous firmware
image.
Multi-frame sequences are
allowed. Transfer Length
for each write must be less
than or equal to 64KB
(65536 bytes).
It is required that the
Parameter list length be the
same as the FCP_DL field
in the FCP_CMND IU.

• Byte 2 set to 0x00,
• Bytes 6-8 set to length of outbound data length
(maximum transfer length is 64K (0x10000)).
• The mode will be set to 0x06 for the first & middle Write
Buffers and 0x07 for the last.
