Some of the current limitations of the main.txt interface are given here. Directories are not
supported for FPGA configuration files. All bit files must be contained in the root directory of
the card. File name lengths for bit files are limited to 8 characters. You can still use bit files with
longer file names by specifying the DOS version of the file name in the main.txt file. For
example, to configure FPGA A with the file
Com_apple_sj45_ethn0_fpga_b_121107b.bit
You can use the main.txt command
FPGA A: com_ap~1.bit
3.4.2
Hardware
The Compact Flash interface is hot-swappable.
An activity LED, DS147, located next to the Compact Flash slot indicates activity on this
interface.
Due to a flaw in the software design, some Compact Flash cards may be incompatible with the
DN9002K10PCI. Please contact
if you find an incompatible card, so
that we can add software support for it.
Also, the board only accepts CompactFlash cards formatted in the FAT file system. Most newer
compact flash cards come pre-formatted with the FAT32 file system. In this case, the
DN9002K10PCI will not be able to recognize files on the card.
3.5
Configuration Registers
The configuration control on the DN9002K10PCI is controlled by setting “configuration
registers”. Basically, these are just locations in the memory space of the on-board micro
controller that controls the board’s function. A full description of the function of this micro
controller is omitted, but some of the registers in this space are required to be accessed over
USB or PCI to control the board. For information on how to access this address space over
USB or PCI, see the corresponding section in this chapter.
REGISTER ADDRESS
FUNCTION
FPGA_RESET
DF22
Write 0x2 to hold reset. 0x0 to release
G0_N_VAL
DF29
Sets the divider value of G0
G0_M_VAL
DF30
Sets the 8442 multiplier of G0
G1_N_VAL
DF31
Sets the 8442 divider value of G1
G0_M_VAL
DF32
Sets the 8442 multiplier of G1
G2_N_VAL
DF33
Sets the 8442 divider value of G2
G2_M_VAL
DF34
Sets the 8442 multiplier of G2
UPDATE_CLOCK_FLAG DF40
When high, each bit causes the configuration circuit to
update the represented clock frequency with the
current M and N values. 0x01 is G0, 0x02 is G1, 0x04
is G2
