2.
Activate the firmware.
# mstflint -d <device> --linkx --downstream_device_id_start_index <port_number> --num_of_downstream_devices

--activate b
Example of Download Transfer with Activation, range is 1 to 2:
# mstflint -d /dev/mst/mt4123_pciconf0 --linkx --downstream_device_id_start_index
num_of_downstream_devices
This will update 2 AOCs/Transceivers starting from port 1, i.e. all ports in the range 1...2.
You cannot 'overburn' the same firmware version into a transceiver/AOC as the one
already installed. This is to prevent wasting time re-burning transceivers in a large
cluster.
Example of successful update of 1 AOC:
-I- Downloading FW ...
FSMST_INITIALIZE -
Writing COMPID_LINKX component -
FSMST_LOCKED -
FSMST_DOWNSTREAM_DEVICE_TRANSFER -
FSMST_LOCKED -
Please wait
while
FSMST_ACTIVATE -
-I- Cable burn finished successfully.
Downloading and burning takes approx. 1½ minute + activation ½ minute for one
cable.
Querying Firmware Information from an AOC / Transceiver
Querying a firmware cable transceiver connected to the host is done using the "flint" tool. To do
so, the user should use the
# mstflint -d <device> --linkx --downstream_device_ids <ids> [--output_file <file_name>] q
Query ports 1,2,5 Example:
# mstflint -d <device> --linkx --downstream_device_ids 1,2
The system responds with information about the firmware version loaded into the transceivers.
Checking successful burning and operation - Example:
It is essential to check that the links come up AFTER the cable FW is updated and reactivated. This
can be done as follows:
#
for
i in {1..2};
do
echo $i; mstlink -d /dev/mst/mt4123_pciconf0 -p $i -m | grep 'Part\|FW\|State'; done
The 'State' parameter was added to the query. The response has the following format (example):
#
1
State
Vendor Part Number
FW Version
2
download_transfer --activate -i image.bin b
OK
OK
OK
