8. 6 Firmware update failures
If a user changes channels away from the source computer
while an update is underway, or if the K4u
+
switch is removed or
reset unexpectedly, the firmware update stops. This may leave
the K4u
+
in an unstable state.
Note that even if you cannot access a K4u
+
over a USB
connection, you can always recover it using its serial interface.
6 Update the main processor firmware:
a. Click the Update Firmware button in the K4u section.
b. In the Load Firmware dialog, browse to the required .DLD
file.
c. In the Confirm dialog, confirm the firmware details for
the Main Processor and Channel Processor. Then click
Yes to start the update.
d. The left pane of the configuration utility shows update
progress. The update typically takes a couple of minutes.
e. When the update is complete, the left pane displays “ISP
completed successfully”.
While the update is running, the power LED flashes
amber and magenta. When update is complete, each
channel LED briefly displays green.
f. Continue to step 8 to update the FPGA configuration.
Important! If the update failed, the left pane displays
“ISP Failed” and the channel LEDs display red. See the
warning in step 6 for instructions.
7 Update the FPGA configuration:
a. Click the Update FPGA Configuration button in the K4u
section.
b. In the Load FPGA Configuration dialog, browse to the
required .K4U file.
c. In the Confirm dialog, confirm the FPGA file details and
click Yes to start the update.
d. The left pane of the configuration utility shows update
progress. The update typically takes slightly longer than
the processor firmware update.
e. When the update is complete, the left pane displays
“Data transmitted successfully”.
Important! If the update failed, see the warning in
step 6 for instructions.
