Reprogramming the EPM7128AE Configuration Controller Device
Reprogramming
the EPM7128AE
Configuration
Controller
Device
The EPM7128AE configuration controller device also must be
reprogrammed.
1.
Move the programming cable from J24 to J5, labeled “For U3”.
1
The orientation of J5 is opposite that of J24. Be sure to rotate the
connector on the end of the programming cable 180 degrees
before plugging it into J5. When properly connected to J5, the
programming cable lies naturally across the FPGA Config LEDs
and the dual seven-segment display.
2.
Launch the Quartus II software, and open the Programmer window
(Tools menu).
3.
Click Add File and select the following programming file:
factory_recovery/
<development board>/config_controller.pof
where <development board> is either the niosII_stratix_1s10 board or
niosII_stratix_1s10_ES
board.
ES development boards have Stratix EP1S10 devices whose part
numbers end with “ES”.
4.
In the Programmer, check the Program/Configure box, and click
Start
to reprogram the EPM7128AE device.
5.
Press the Safe Config button to perform a power-on reset and
reconfigure the Stratix device from flash memory. You should see
the Safe LED turned on and activity on LEDs D0 through D7.
Your board is now re-configured to the default factory condition.
