210 In-Band Management Appendix B

Note Multiple Upgrade Firmware commands will generally be

required to transfer the entire program image from the host to

the bridge DRAM. When the last data block is transferred (mode

= 0x07) the bridge terminates data transfer and performs a CRC

checksum on data received.

It is required that the FC initiator sends sequentially 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 bridge

will use the newly upgraded firmware. The previous firmware

image is discarded. 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.
