The Altera Cyclone II FPGA can be initialized using several methods.
First, the FPGA can be programmed over the IOS Bus using the Passive
Serial technique. This technique requires the programming bus jumper to
be set to the “IOS” position. The initialization interface utilizes six signals.
nConfig, Conf_Done, Init_Done, nStatus, DCLK, and Data0.
The second and third method involve programming via the JTAG
interface. This interface can be used to either direct program the FPGA or
indirectly program the FLASH device. When programming the FLASH
device, the FPGA acts as a bridge between the FLASH device and the
JTAG interface. Once programming the FLASH is completed, the FPGA will
load the program file from FLASH at power-up if the programming jumper is
set to the “FLASH” position.
Refer to the Configuring Chapter of the Cyclone II Device Handbook
from Altera for further information.
Surface-Mounted Technology (SMT) boards are generally difficult to
repair. It is highly recommended that a non-functioning board be returned to
Acromag for repair. The board can be easily damaged unless special SMT
repair and service tools are used. Further, Acromag has automated test
equipment that thoroughly checks the performance of each board. When a
board is first produced and when any repair is made, it is tested, placed in a
burn-in room at elevated temperature, and retested before shipment.
Please refer to Acromag's Service Policy Bulletin or contact Acromag for
complete details on how to obtain parts and repair.
Before beginning repair, be sure that all of the procedures in Section 2,
Preparation For Use, have been followed. Also, refer to the documentation
of your carrier/CPU board to verify that it is correctly configured.
Replacement of the board with one that is known to work correctly is a good
technique to isolate a faulty board. Use the unmodified example we
provided.
